 2012-06-03 16:58:19 +09:00
rmackay9 080c5184d5 ArduCopter Desktop Build: added definition of "map" to wiring.h and included WMath.cpp to fix SITL build failures. 
All real work on this issue done by Michael Oborne.
 2012-06-02 17:46:00 +09:00
rmackay9 8f3169a200 AP_MotorsHeli: Added reference to "Arduino.h" to allow autotest builder to work.

 2012-06-02 16:13:23 +09:00
rmackay9 3246f2bad3 RC_Channel library: change all "int" types to "int16_t". 
Fixes SITL compile error due to type mismatch of set_pwm between .h and .cpp file (this only occurs because on the SITL, "int" is actually "int32_t"
 2012-06-02 14:20:58 +09:00
rmackay9 37e4637c13 RC_Channel.pde: fixed compile errors so that it actually works! 2012-06-02 14:00:44 +09:00
rmackay9 df3fb5c041 ArduCopter: fixed print_latlon bug in which it would print negative lat/lon numbers incorrectly (i.e. -1234567890 would be printed as -124.xxx). 2012-06-02 12:51:12 +09:00
Jason Short 477aa6e47a RC_Channel fix for throttle output. 
throttle was outputting incorrectly and allowing the user to max out the throttle leaving nothing for attitude control
 2012-05-31 14:59:03 -07:00
Jason Short 7ee38df5a2 Issue 416: RC_Channel – Fix to make dead_zones still output 0 2012-05-31 12:05:47 -07:00
Jason Short 2cc9fde3c9 removed never used filter, and fixed a constrain that could make range calcs go bad 2012-05-31 11:45:07 -07:00
Jason Short 00cabc6343 Channel rage fix - low output was always 0 vs _low 2012-05-31 11:31:48 -07:00
Robert Lefebvre bafb478924 TradHeli: Incorporating Ext ESC Control 2012-05-30 21:50:25 -04:00
Robert Lefebvre ffc04b7305 Fix TradHeli Collective Yaw Effect bug. 2012-05-25 15:25:21 -04:00
Andrew Tridgell 734dcebb2a SITL: fixed ChipErase() 
the loop never completed
 2012-05-23 21:15:45 +10:00
Andrew Tridgell 5e0d937e50 SITL: fixed build with new ChipErase() call 2012-05-23 17:33:33 +10:00
Andrew Tridgell c2fb8a7a98 DataFlash: use ChipErase() instead of PageErase() on all pages 
This makes the DataFlash erase much faster (about 6 seconds instead of
about 60 seconds).

We need to test and ensure the behaviour is equivalent apart from the
speed
 2012-05-22 19:29:02 -07:00
Andrew Tridgell 8f27297896 DCM: fixed a bug when using GPS for yaw correction 
When using GPS for yaw correction we need to apply the x and y omegaI
corrections from the _omega_I_sum in the period before we get to the
minimum ground speed for GPS yaw correction. Otherwise we get a large
sudden omega_I change on takeoff.
 2012-05-21 12:15:06 +10:00
Andrew Tridgell 37f652e19b AP_Common: fixed some duplicate product ID warnings 2012-05-17 23:37:32 +10:00
rmackay9 eaeaa3811a ArduCopter: bug fix for reversing tri servo 
Extended AP_MotorsTri class to take in pointer to rc_tail servo (rc_7) and we use this servo's REV parameter to determine whether to reverse the output to the tail servo or not
 2012-05-13 12:36:46 +09:00
Craig Elder fe742f1c23 IMU: expose IMU_PRODUCT_ID as EEPROM Variable 
this will allow us to log the Product ID in tlogs
 2012-05-09 18:30:36 -07:00
Craig Elder c323a71933 AP_InertialSensor: Return product ID from sensor initialization

 2012-05-09 18:30:36 -07:00
Craig Elder a22b15adf1 PRODUCT: Define product IDs for all supported products 2012-05-09 18:30:36 -07:00
Craig Elder b824a87b90 MPU6000: Fixed Scaling on Accelerometers Rev C vs Rev D 
Rev C have non standard scaling factor that is 1/2 of the data sheet
Rev D chips conform to the specification
 2012-05-09 18:30:35 -07:00
Chris Anderson 46614e9acd fixed typo ("minimum" should have been "maximum") 2012-05-06 15:50:19 -07:00
Andrew Tridgell 76a3fd9a4e MPU6k: added suspend/resume on init 2012-05-01 12:06:54 +10:00
Andrew Tridgell ae1702c20b Baro: added suspend/resume on init 2012-05-01 12:06:54 +10:00
Andrew Tridgell 3115d48ba1 ADC: added suspend/resume on init 2012-05-01 12:06:54 +10:00
Andrew Tridgell 57ac39649a TimerProcess: added suspend_timer()/resume_timer() 
this will be used to avoid races in driver initialisation
 2012-05-01 12:06:54 +10:00
rmackay9 3b2d203f0f AP_AHRS: updated default AHRS_YAW_P to 0.2 (was 0.4) 
This reduces the compass's default authority over the yaw direction by half
 2012-04-30 17:29:45 +09:00
Andrew Tridgell 8f2cecae4d MAVLink: re-generated with new pygen 
this moves the enums to make them less order sensitive
 2012-04-30 12:27:30 +10:00
Adam M Rivera 292f9699fa Parameters.pde/AP_MotorsHeli: Updated comments to leverage the new value aliases 2012-04-28 20:50:41 -05:00
Andrew Tridgell 3177f57d48 build: cope with Arduino 1.0 in command line build 
this should autodetect 1.0 versus older builds
 2012-04-27 15:38:42 +10:00
Adam M Rivera 21886104a6 Parameters.pde/AP_MotorsHeli.cpp: Added comments from Roberts clone. 2012-04-26 18:26:14 -05:00
Adam M Rivera b1f19dbb01 AP_AHRS_DCM.cpp: Added comments that follow the new parse structure 2012-04-25 12:00:42 -05:00
Andrew Tridgell 532ac607b2 sitl: support MAVLink 1.0 builds 2012-04-24 22:24:58 +10:00
Andrew Tridgell fef4134702 MAVLink: removed the cpp part of the library 
this was preventing building MAVLink 1.0 with the arduino GUI as we
can't set cpp defines
 2012-04-24 22:24:58 +10:00
Andrew Tridgell 9bf8d60dae MAVLink: one more define for MAVLink 1.0 compat 2012-04-24 19:54:20 +10:00
Andrew Tridgell fd9d2f856e MAVLink: re-add the XML message definitions 
these are a very useful reference for the current headers in the code
 2012-04-24 10:57:43 +10:00
Andrew Tridgell a54cd57568 MAVLink: imported new mavlink header updates 
this fixes the camera control code which was broken by a previous
import
 2012-04-24 10:57:43 +10:00
Andrew Tridgell bff8fc8947 APM_RC: added OutputCh_current() method 
this allows logging of the actual servo output values. The radio_out
method previously used doesn't take account of the various override
mechanisms available via waypoints
 2012-04-24 10:57:43 +10:00
Andrew Tridgell 6d837891b0 DCM: buffer omega_I changes over 10 seconds 
this buffers up _omega_I changes in _omega_I_sum over a period of 10
seconds, applying the slope limit only when _omega_I_sum is
transferred to _omega_I.

The result is a huge improvement in the ability of _omega_I to track
gyro drift over the long term.
 2012-04-23 12:13:25 +10:00
Andrew Tridgell 398a608b83 DCM: drop the 'drop z' method 
the 'drop z' method reduced the impact of noise on omegaI, but it also
made us more sensitive to errors in accelerometer calibration and
scaling, as demonstated by the logs from Gabor here:

  http://diydrones.com/xn/detail/705844:Comment:834373

Simulation testing shows that the other noise suppression methods
applied in the DCM code, in particular the slope limiting on omegaI
the removal of the weighting and the upcoming use of a _omega_I_sum
buffer have reduced the impact of noise enough that we can now safely
include z in the acceleration calculation.
 2012-04-23 12:13:24 +10:00
rmackay9 c62ce95768 AP_Motors - allow tail servo to be reversed. Closes ArduCopter issue #228 2012-04-21 23:07:57 +09:00
rmackay9 346ca5c865 DataFlash_APM2 - moved CS_inactive call (which disables the dataflash) from the beginning to the end of all methods. This means the dataflash does not monopolize the SPI bus. 
Also formatting changes to use tab instead of space. Sorry, should have done this as a separate check-in to the above changes.
 2012-04-21 20:14:45 +09:00
rmackay9 577f18a09c AP_OpticalFlow - updated test sketch to allow testing of APM2 version 2012-04-21 20:11:18 +09:00
rmackay9 e9fd7c955d AP_OpticalFlow - added support for optical flow for APM2 2012-04-21 20:10:35 +09:00
rmackay9 026cd4e64f AP_OpticalFlow - moved most pin definitions into .cpp file 2012-04-21 20:09:15 +09:00
James Goppert 750c30afc1 MAVLink update to 1.0.7 2012-04-20 12:31:50 -04:00
Andrew Tridgell 4652b30adf GPS: u-center config file for 3DR Ublox 2012-04-20 22:05:30 +10:00
Andrew Tridgell 0b194259be GPS: fixed auto GPS test 2012-04-20 22:05:30 +10:00
Andrew Tridgell 3141cfe059 GPS: detect new style 3DR UBlox 2012-04-20 22:05:30 +10:00
Andrew Tridgell 64d5f4c26a GPS: fixed the UBlox test code 2012-04-20 20:57:08 +10:00
James Goppert b5ca40e8c5 Updated MAVLink to 1.0.6 release. 2012-04-19 15:46:29 -04:00
Adam M Rivera 2c8cd0b07b AP_AHRS_HIL.h: Fixed HIL build by adding missing public property. 2012-04-16 10:26:14 -05:00
Andrew Tridgell a9de75156b AHRS: added AHRS_YAW_P parameter 
this allows users to change the yaw gain in DCM
 2012-04-16 20:55:13 +10:00
analoguedevices ce5d71c08c added missing #include 2012-04-09 14:32:54 +00:00
rmackay9 4dac4c4c11 AP_AHRS - changed parameter order to remove compiler warning 2012-04-09 17:37:11 +09:00
rmackay9 cc191b86c0 AP_Compass - changed parameter initialisation order to remove compiler warning 2012-04-09 17:37:02 +09:00
Andrew Tridgell 7921d33c40 MAVLink: imported new mavlink headers 
this adds local and remote radio noise levels
 2012-04-08 12:22:17 +10:00
rmackay9 1b4ac37e66 AP_MotorsMatrix - fixed stability patch issue in which it would not limit a motor's output unless an opposite motor had been defined. This would only have affected Y6 frames. 2012-04-07 12:16:12 +09:00
rmackay9 e63e858b64 AP_MotorsOcta - V Frame - test order fix spotted by David Wiens 2012-04-07 08:11:28 +09:00
rmackay9 d0cbd577cd AP_Motors - fixed last "shadowing" compiler warning caused by badly named parameter in auto_armed method. 2012-04-05 00:28:04 +09:00
rmackay9 c27b83c8a8 AP_MotorsMatrix - fixed another compiler error regarding shadowing a variable. Fixed by removing those the angle and direction arrays which weren't even used 2012-04-05 00:24:56 +09:00
rmackay9 e9f0103063 AP_MotorsHeli - fixed compiler warning re move_swash function declared with int parameters in .h file but actually using int16_t in .cpp file. They're the same in arduino but perhaps the build checker is a little more strict that Arduino. 2012-04-05 00:06:33 +09:00
rmackay9 40e5a15452 AP_Motors - fix compiler warning re shadowing a variable caused by badly named parameter in armed function. 
Another compiler warning fixed in AP_MotorsMatrix.cpp caused by declaring "i" twice.
 2012-04-04 23:59:51 +09:00
rmackay9 71ad185238 ArduCopter - AP_Motors library - added new library which has few advantages over current code: 
1. it's step towards rearchitecting the current code base ahead of a move to RTOS.
     2. internally it uses a MatrixTable for the Quad, Octa, OctaQuad, Y6 frames.
     3. it implements the missing stability patch for Octa and OctaQuads (still missing for Y6)

Later check-ins will incorporate into the main ArduCopter code.
 2012-04-02 17:26:37 +09:00
Andrew Tridgell 5ce5f3d176 MAVLink: import change to txbuf as a percentage 2012-04-02 11:18:53 +10:00
Andrew Tridgell 8a215c8b55 MAVLink: imported new headers, with RADIO packet 2012-04-01 21:44:44 +10:00
Andrew Tridgell 08b66e18b7 FastSerial: added set_blocking_writes() interface 
this allows us to put a serial port into non-blocking mode, so that
writes that don't fit in the transmit buffer are dropped. This will be
used in flight to prevent stray printf() calls from causing large time
delays in the code
 2012-03-30 17:46:20 +11:00
Andrew Tridgell c2ff66c9cd examples: fixed build of some examples with new AP_Declination code 2012-03-30 14:25:27 +11:00
Andrew Tridgell 825340d53d Compass: added COMPASS_AUTODEC option 
when this is 1 (which is the default), we will get the declination
automatically via the AP_Declination library

when it is 0 we will use the value configured by the user
 2012-03-30 14:25:27 +11:00
Andrew Tridgell e4e052ff91 AP_Declination: save some more memory by putting the declination keys in progmem 
there was a comment saying this was too slow, but it actually costs
about 30 usec extra, which is trivial given the full auto declination
call costs 680 usec and its only called once per boot
 2012-03-30 14:25:27 +11:00
Andrew Tridgell edb627a5c1 AP_Declination: added timing information to declination test 2012-03-30 14:25:27 +11:00
Andrew Tridgell 01c4cde14f AP_Declination: fixed build under SITL 2012-03-30 14:25:27 +11:00
Adam M Rivera 9c414e9573 AP_Declination_test: Updated test with better print messages. 2012-03-30 14:25:26 +11:00
Adam M Rivera cff189e911 AP_Declination: Update LUT based on the changes that I made in the LUT generation code. This LUT is the final version that has no truncation. 2012-03-30 14:25:26 +11:00
Adam M Rivera 380b9ece44 AP_Declination: Updated comments to reflect new LUT size. 2012-03-30 14:25:06 +11:00
Adam M Rivera c04e074c89 AP_Declination: Removed trailing zero deltas as they have no impact on the final value and only take up extra bytes. 2012-03-30 14:21:58 +11:00
Adam M Rivera 662f11f801 AP_Declination: Updated compressed lookup value table. Located 9 more failure points due to truncation on the packed LUT. 2012-03-30 14:21:58 +11:00
Adam M Rivera 0178906389 AP_Declination: Found 7 of the 22 failure points and fixed them. The issue with those 7 was the way I originally packed the value array. The last delta values on some rows were getting truncated. The new number of failures is down to 15 - WIP. 2012-03-30 14:21:58 +11:00
Adam M Rivera 08259bb2de AP_Declination: Updated test to run in 5 degree increments. Changed to only print failures and also print total pass vs total fail. 2012-03-30 14:21:58 +11:00
Adam M Rivera 64c236800c AP_Declination: Moved check for y index of zero to after the y index is properly transformed. 2012-03-30 14:21:58 +11:00
Adam M Rivera e99d26cfa3 AP_Declination: The exception signs unpacking logic was incorrect. I was shifting a 1 value left y%8 which would have needed a the signs to be packed right to left. My packed signs byte was packed left to right (left most being the 0 position) so I needed to reverse the shifting. 2012-03-30 14:21:58 +11:00
Adam M Rivera d9c9e0e608 AP_Declination: In order for the bitwise & operation to work, negative signs need to be represented by 1s instead of 0s. Changed so that negative signs are represented by a 1 in the packed signs array. Updated lookup logic to reflect this change. 2012-03-30 14:21:58 +11:00
Adam M Rivera 8b1c383f97 AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly. 2012-03-30 14:21:57 +11:00
Adam M Rivera c0813f8d62 AP_Declination: Changed test to run in increments of 10 degrees. 1 was too granular. 2012-03-30 14:21:57 +11:00
Adam M Rivera 289d7a2784 AP_Declination: Added original array to test sketch. Added loop to validate new compressed array against original in 1 degree steps. 2012-03-30 14:21:57 +11:00
Adam M Rivera 63ce400f77 AP_Declination: Moved rows with large spikes in delta to their own unsigned exception rows. The signs are in a separate packed array. 2012-03-30 14:21:57 +11:00
Adam M Rivera 782c1aaaa3 AP_Declination: Implemented Delta Encoding and Run-Length Encoding. Added method to traverse the compressed array and return the lookup value based on the same lat_index/lon_index that was used before. 2012-03-30 14:21:57 +11:00
Adam M Rivera 9888a4730f AP_Declination: Changed PROGMEM read function to pgm_read_word_far to support the int16_t datatype. 2012-03-30 14:21:57 +11:00
Adam M Rivera d883bdf75e AP_Declination: Changed datatype to int16_t to support the -90 <-> 90 latitude range. 2012-03-30 14:21:57 +11:00
Adam M Rivera 719636d00c AP_Declination: Reduced the size of the lookup table to support -75 <-> 70 latitude range. This allows the datatype to remain int8_t. 2012-03-30 14:21:57 +11:00
Andrew Tridgell 071f89df2e AHRS: fixed error_yaw reporting with 2 MAVLink connections 
when a user first connects with USB, and later switches to the
telemetry port without restarting we were getting zero for error_yaw
in the logs, as AHRS.get_error_yaw() was being called twice.

This ensures we give the last value after the counter is reset
 2012-03-29 12:39:53 +11:00
Andrew Tridgell 20941c15c3 Compass: fixed a comment 2012-03-29 12:39:53 +11:00
Andrew Tridgell 79deeef0a0 Compass: added some more comments 
explain the algorithm a bit more
 2012-03-29 12:39:53 +11:00
rmackay9 fd5e1c2f7b Filter - added FilterWithBuffer typedefs for int32t and uint32 for ease of use 2012-03-28 22:02:52 +09:00
rmackay9 99cdc69110 AP_OpticalFlow - small bug fix to ensure init attempts to read the product id 3 times before giving up 2012-03-28 22:00:57 +09:00
Andrew Tridgell 972bdcfa39 SITL: add magnetic field noise to the simulated compass 2012-03-28 20:55:27 +11:00
Andrew Tridgell dc127fe749 SITL: ensure we don't run the sitl timer twice 
this caused problems with random()
 2012-03-28 20:55:27 +11:00
Andrew Tridgell 2a011578f9 Compass: implement noise resistant varient of offset learning 
This adds a large amount of noise robustness to the compass offset
learning algorithm, at a cost of 120 bytes of memory. The changes are
based on a long discussion with Bill Premerlani.
 2012-03-28 20:55:27 +11:00
Andrew Tridgell 16f094a1c5 ADC: minor fix to the ADC Ch6() code 
we don't need to add count any more, as floating point maths doesn't
need to round up
 2012-03-27 15:37:24 +11:00
Andrew Tridgell a3d3dd86cf Compass: implement Bills new offset nulling algorithm 
this seems to work much better than the old algorithm, converging
faster and more accurately. Even better, it has no linkage to DCM, so
no possibility of nasty feedback effects
 2012-03-27 15:37:24 +11:00
rmackay9 cf1a6f8ab8 APM_RC - moved Force_Out0_Out1, Force_Out2_Out3 and Force_Out6_Out6 to APM_RC parent class because it's already implemented in the APM1 and APM2 child classes anyway 2012-03-25 21:13:31 +09:00
rmackay9 2324be7e68 Filter - added simple LowPassFilter (simple but it's possible to make errors with simple stuff too so might as well have one) 2012-03-25 16:15:25 +09:00
rmackay9 bdda74fd28 Filter - remove obsolete warning from comments re alloc/malloc dangers 2012-03-25 16:14:07 +09:00
rmackay9 dc58c8a905 AP_Baro - change data type size of temperature's average filter to int32_t (was int16_t) 2012-03-24 23:21:11 +09:00
rmackay9 766abb8e6c AP_OpticalFlow - resolved compile error in example sketch (it could not find DCM.h but it's not required anyway) 2012-03-24 14:47:21 +09:00
Andrew Tridgell 477b31fb0d Math: added mul_transpose() operation 
this is equivalent to multiplying by m.transposed(), but is more
efficient
 2012-03-23 16:48:52 +11:00
Andrew Tridgell 1b3a7d47bd AHRS: fixed build of AHRS example 2012-03-22 23:00:45 +11:00
Andrew Tridgell fb9790e1f4 Math: moved matrix multiple operations to .cpp file 
this means we only link this in once, rather than for every use of
matrix multiply, which saves us some flash space

We need to be careful not to put large pieces of code in template
headers, as if the operation is used a lot, it costs us a lot of code
space

- also removed unused _offset_press variable
 2012-03-18 15:18:05 +09:00
rmackay9 ed0d1da4f5 AP_Baro - added average filter for temperature to replace broken filter

timing of the older releases - about 10 seconds for a 1 radian change
in heading
 2012-03-12 17:49:26 +11:00
Andrew Tridgell aa408655f8 Compass: fixed the order of rotations in the compass driver

Andrew Tridgell f71311fdc0 Quaternion: fix the gyro bias in centripetal and remove smoothing 
the centripetal code needs to take account of the current gyro
bias.

It turned out that the accel and gyro smoothing was causing
significant control lag, and we're better off just letting the
quaternion code handle it via its own smoothing parameters

Andrew Tridgell 55413bfcc1 DCM: don't use the z accel sensor for drift correction 
the z accel is the noisest, and seems to do more harm than good. Using
just x and y is sufficient for drift correction by assuming the vector
length

Andrew Tridgell 82032b17a9 DCM: added reporting interfaces for DCM state 2012-03-10 10:34:27 +11:00
Andrew Tridgell ae6a94a933 SITL: added sitl_simstate_send() 
used to report simulator state in logs
 2012-03-10 10:34:27 +11:00
Andrew Tridgell d106e3a970 MAVLink: import new message types DCM, HWSTATUS and SIMSTATE 2012-03-10 10:34:27 +11:00
Andrew Tridgell 4e354a9731 DCM: got rid of _error_roll_pitch from object state 
this can be a local error variable in common with the yaw code. This
saves 12 bytes in the object.

Jason Short 13e9608fb8 Consolidated Barometer pressure sensing to a single filter based on Randy's new filter class. 2012-03-08 23:13:04 -08:00
Jason Short 34cf1e8fb3 Updated on Barometer - increased the Temp filtering and decreased the pressure filtering to and get less temp noise, faster response from pressure. I'm filtering the Climb rate differently now, so this higher pressure noise should not hurt the derivative calcs at all now. 2012-03-06 20:55:35 -08:00
rmackay9 6c1299fe7e AP_RC - removed unused library 2012-03-04 18:21:52 +09:00
Andrew Tridgell dd9065123c SITL: use the new noise model

Andrew Tridgell 63ea5dfb49 APM_RC: allow the fast RC speed to be passed as a parameter 
this will allow users to test different speeds
 2012-03-02 17:57:08 +11:00
Andrew Tridgell f1a389fe19 AP_Param: ensure we can't have duplicate keys in Parameters.h 
this is O(n^2), but only at startup, and takes less than 1ms to run.
It catches a very nasty coding error
 2012-03-02 15:48:28 +11:00
Andrew Tridgell 1476f044e6 I2C: added lockup_count() interface 
used for reporting I2C problems
 2012-03-02 15:48:27 +11:00
Andrew Tridgell c9031f1d36 SITL: implement cli()/sei() properly for desktop build 
this disables simulated hardware interrupts during critical sections

Pat Hickey 42078f2794 AP_Param: Make nested group recursion disableable by macro 
* Eliminates recursive calls inside AP_Param.
  This is important to Pat @ Galois, but not the project in general.
  Recursion depth on these functions is bounded structurally using
  existing nested group constructors (can't create loops in finite space)
  and checked at init time
 2012-02-28 16:28:27 -08:00
rmackay9 400a4b0bdb AP_RangeFinder - changed example sketch to work with new Filter library 2012-02-28 21:02:10 +09:00

Andrew Tridgell 078268528e AP_Param: show numerical value in eeprom dump utility 2012-02-28 09:43:49 +11:00
Andrew Tridgell 701da6c30f AP_Param: fixed v.load() on a sub-element of a AP_Vector3f 
this isn't actually used at the moment in APM, but we should get it
right in case someone does try to load a single element of a vector
 2012-02-28 09:43:49 +11:00
Andrew Tridgell 34f1ebcfb4 SITL: simulate noise on each ADC channel separately

 2012-02-28 09:43:49 +11:00
Andrew Tridgell 4cdc0a8c11 SITL: raise the ADC noise level to 8 bits when flying 
this is about the level of noise of a aircraft that has a lot of
vibration
 2012-02-28 09:43:49 +11:00
Andrew Tridgell b32701e008 IMU: removed unused accel_filtered code 2012-02-28 09:43:49 +11:00
Andrew Tridgell ac44b73951 AP_Param: fixed setting of CAM_P_G in ArduCopter 
the variable CAM_P_G has the same prefix as the CAM_P group. We want
to allow for parameters having a common prefix with a group, so we
need to keep searching after we've found a group that matches the
prefix
 2012-02-27 10:54:33 +11:00
Andrew Tridgell 7fe4a41c31 AP_Param: make the templating code a bit clearer

 2012-02-27 10:54:33 +11:00
Andrew Tridgell 5bf138fb38 DCM: fixed the sense of the compass GPS test in initial yaw 
we were only disabling null offsets when we didn't have a compass,
which doesn't make much sense!

rmackay9 747e045193 ModeFilter - corrected shadowed variable compiler warning for drop_high_sample 2012-02-26 17:57:28 +09:00
rmackay9 e01477a7a8 Filter - added AverageFilter - this will be used in place of SumFilter because it removes the possibility of overflows 2012-02-26 17:34:36 +09:00
rmackay9 b345529241 Filter - removed shadowing of variables in constructors for Filter, ModeFilter and SumFilter (sorry tridge!)

Andrew Tridgell bd2776aedd Compass: use constructor to set initial values for _learn and _use_for_yaw 
this ensures they are set if you have MAG_ENABLE==0
 2012-02-25 17:36:31 +11:00
Andrew Tridgell 56bb74ef36 DCM: disable compass null offsets when setting initial yaw 
we need to ensure the compass null offsets code doesn't see a sudden
yaw change, or it will change the offsets by a large amount very
suddenly
 2012-02-25 16:02:24 +11:00
Andrew Tridgell f50f4357ca Compass: catch the case of a user enabling a compass mid-flight 
if a compass has not been initialised at startup we can't enable it
mid-flight, as we don't have the orientation
 2012-02-25 14:51:09 +11:00
Andrew Tridgell 3abe035557 DCM: use the new use_for_yaw() compass method 2012-02-25 14:51:09 +11:00
Andrew Tridgell c3319afadd Compass: added COMPASS_LEARN and COMPASS_USE parameters 
these allow you to control if the compass should be used for yaw and
if it should learn its offsets. This is useful for locking in compass
offsets once they are confirmed to be good, and for learning offsets
without using them in flights.

The default is to behave the same as previously, which is
COMPASS_LEARN=1 and COMPASS_USE=1
 2012-02-25 14:51:08 +11:00
Andrew Tridgell 051bd78b37 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 3cf0eebac8 DCM: don't reset _have_initial_yaw for GPS heading unless very slow 
wait till we reach 1m/s before we reset _have_initial_yaw. This
prevents us continually resetting the DCM matrix if our ground speed
is close to 3m/s.
 2012-02-25 11:37:20 +11:00
Andrew Tridgell 007a6b8958 AP_Param: added special handling for Vector3f 
We would like to be able to use Vector3f as a parameter while exposing
the individual elements of the vector as MAVLink parameters. This
change to AP_Param makes that possible, by giving AP_Vector3f a dual
personality
 2012-02-25 11:37:20 +11:00
Andrew Tridgell 1d95137b71 SITL: added -C option to desktop mode 
this allows running APM to stdout, which is useful for test sketches
 2012-02-25 11:37:20 +11:00
Andrew Tridgell f221bd13ab libs: removed unused library GPS_IMU 2012-02-25 11:37:20 +11:00

Andrew Tridgell c63ca9c697 DCM: tidy up use of error_course and in_motion 
in_motion is not a good name now it is also used for the compass

The error_course and heading component values don't need to be part of
the DCM object, they can be on the stack to reduce the memory usage a bit
 2012-02-25 11:37:20 +11:00
Andrew Tridgell d5b619218c DCM: use rotation_matrix_from_euler() to calculate initial yaw 
When we first get a compass reading or we first start motion we need
to setup the DCM matrix with the right yaw. This uses
rotation_matrix_from_euler() to get a DCM matrix corresponding to our
current roll/pitch, but with the correct yaw
 2012-02-25 11:37:20 +11:00
Andrew Tridgell 48cad8bc25 DCM: use rotation_matrix_from_euler() in matrix reset 
this makes the code a bit easier to read
 2012-02-24 11:54:11 +11:00
Andrew Tridgell 5009679617 DCM: use calculate_euler_angles() to get eulers from DCM 
this makes the code a bit easier to understand
 2012-02-24 11:52:55 +11:00
Andrew Tridgell df6013616e AP_Math: added rotmat <-> euler functions 
these will make the dcm matrix manipulation easier to understand
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 50f85835bd Compass: ensure we don't produce NAN values for compass heading 
this leaves the previous heading values alone if we are at a pitch of
exactly 90 or -90, at which point we can't compute a meaningful
heading
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 8190204287 AP_Math: added safe_sqrt() function 
this function will never return NAN. It will return zero for negative
numbers.
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 0acea11152 DCM: tidy up the nan checking in DCM 
use is_nan() on the matrix rather than just on c.x, and add
safe_asin() to the (unused) OUTPUTMODE==2 code.
 2012-02-24 11:52:55 +11:00
Andrew Tridgell b4c8d6491a DCM: added matrix recovery on reset 
when we get a bad DCM error we can recover a matrix corresponding to
the current attitude, making it more likely that the aircraft will be
able to recover
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 1a32ececb4 AP_Math: added a safe_asin() function 
this adds range checking to asin()
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 7dd909a16b AP_Math: added is_nan() methods to vector3f and matrix3f 2012-02-24 11:52:55 +11:00
Jason Short 2a4b7facaa added set integrator 2012-02-23 09:38:08 -08:00
Andrew Tridgell 8707965c15 DCM: changed the sense of floating point range comparison 
This allows us to detect NaN, otherwise NaN values were considered 
'in range'
 2012-02-23 11:41:26 +11:00
Andrew Tridgell 9caa4aeb44 DCM: range check the matrix before calculating pitch 
The asin() in the pitch calculation can only take values between -1
and 1. This change ensures that the value is in range, and if it isn't
then we force a normalization. If that fails we reset the matrix
 2012-02-23 08:16:08 +11:00
Andrew Tridgell 13693e1a04 DCM: reset more values on renorm blowup 
when DCM blows up, we need to reset a lot more variables to ensure
that any NaN values don't persist
 2012-02-23 08:16:08 +11:00
Andrew Tridgell 5cfe1ad5dc DCM: remove the taylor expansion optimisation for renormalisation 
The sqrt() costs about 44usec on a 2560, which is small enough for us
not to worry about the speed.

This also changes the range of values where we declare a blowup to
much less likely, which means we can cope with larger delta_t glitches
 2012-02-23 08:16:08 +11:00
Andrew Tridgell f30c721886 AP_Param: added ParamToken type for variable list traversal 2012-02-19 17:05:28 +11:00
Jason Short 669e8e34ea added a limit to range output 2012-02-18 21:08:17 -08:00
Randy Mackay 0b369cf78b Optflow - added reference to FastSerial to resolve compile error on Arduino 1.0. 
also removed reference to DCM (no longer required) and removed some old code.
 2012-02-18 18:09:40 +09:00
Andrew Tridgell 2472f0a2f3 SITL: increase the amount of noise in the simulated ADC 
this increases the noise to 2 bits, which actually can have the effect
of improving accuracy, as it leads to better averaging
 2012-02-18 19:27:15 +11:00
Andrew Tridgell 9602b1f91b DCM: only add in centripetal accel if we have GPS lock 
if we don't have a GPS or the GPS doesn't have a good lock then we
can't rely on the ground speed for adjusting the acceleration vector
 2012-02-18 19:27:15 +11:00
Andrew Tridgell 371a91cfcf IMU: move _sensor_cal to general IMU class 
this makes it available both in shim and INS subclasses
 2012-02-18 10:51:57 +11:00
Andrew Tridgell 2b8f0c3a48 AP_Param: moved AP_Vector3f and AP_Matrix3f declarations to AP_Math.h 
this avoids us needing AP_Math.h in every utility sketch and example
 2012-02-18 10:51:57 +11:00
Andrew Tridgell 70a135c47c AP_Param: fixed copy-assignment operators for AP_Param vectors 2012-02-18 10:51:57 +11:00
Andrew Tridgell e656928c01 AP_Param: added a set_and_save_ifchanged() method 
this can be used to avoid the scan() in more frequenctly saved
variables, such as the MAVLink stream rates in APM
 2012-02-18 10:51:57 +11:00
Andrew Tridgell 6f080742b8 AP_Param: added an initialised() method 
this will be used by the compass code
 2012-02-18 10:51:57 +11:00
justinbeech 5255512bf9 Found free extra 256 bytes of RAM eliminate _clz use from libgcc 
Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment.

The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz
The _clz table gets pulled in if you do 64 bit division.
This tiny change is the only place that we do long long division.
Changing to a shift saves 256 bytes of ram.
 2012-02-17 09:46:05 +00:00
Jason Short 560985b509 made I term return in same pattern as D term 2012-02-16 22:09:22 -08:00
Andrew Tridgell 3fbb5a2d6c ADC: on channel overflow we should not zero last_ch6_micros 
this happens every 64 seconds because of unused channels on the
ADC. Zeroing this creates a bad delta_t value for the DCM code.
 2012-02-16 17:48:36 +11:00
Jason Short 8e88d9e19e change constant to float 44330.0 2012-02-15 09:10:14 -08:00

Andrew Tridgell 63d768143d Compass: enable compass offsets for HIL compass 
this makes the null_offsets algorithm have an effect for the HIL

Andrew Tridgell 812b7ae5ae SITL: catch floating point errors 
if we get a FPE then log a message and exit
 2012-02-15 08:50:45 +11:00
Andrew Tridgell c39914e734 DCM: added a SITL_debug() for DCM normalisation errors 
I have seen normalisation errors during simulation runs, but have not
yet tracked down the cause. This log message may help track things
down.
 2012-02-15 08:50:45 +11:00
Andrew Tridgell 7355f5613c added SITL_debug() macro 
this can be used to print a message into the logs in the SITL
simulator. This will be used for critical conditions.
 2012-02-15 08:50:45 +11:00
Andrew Tridgell 7ba65aecf3 RC_Channel_aux: fixed a uninitialied variable error, and save a bit of stack space 2012-02-15 08:50:45 +11:00

Andrew Tridgell 6c20ff9492 AP_Param: allow dumping of AP_Vector3f 
this means the 'show' command in the CLI shows the compass offsets now
 2012-02-14 08:34:50 +11:00
Andrew Tridgell 4ec3857476 GPS: change back to 4Hz for MTK GPS 
this will hopefully fix the NO_GPS problems that have been regularly
happening in recent months. I will watch the logs carefully to see if
the problem recurs
 2012-02-13 22:50:20 +11:00
Andrew Tridgell e70e1814ac AP_Baro: fixed some signed/unsigned warnings

Andrew Tridgell 550b0be231 move AP_Var code and example into libraries/AP_Var 
you can use AP_Var by defining USE_AP_VAR

Andrew Tridgell d41c56214c fixed types in GPS detect code 
using int everywhere is wasteful and non-portable
 2012-02-13 16:22:53 +11:00
Andrew Tridgell 16a5b5c3ee added AP_Param::show_all() 
this moves the logic into common code
 2012-02-13 16:22:52 +11:00
Andrew Tridgell ee2cb32a44 change back to 256 max variables in _var_info[] 
this keeps the header to 24 bits, and allows the token to be 16
bits. If we need more variables we can put them in a nested group.
 2012-02-13 16:22:52 +11:00
Andrew Tridgell 6cf7015859 added indexes to group info structures 2012-02-13 16:22:52 +11:00
Andrew Tridgell 7621b96a52 AP_Param: added group idx, and change packing of header elements 
adding a idx element to the GroupInfo will make it less likely that a
developer will change the IDs of group elements, and make it easier to
see that these IDs are important for identifying a variable in EEPROM

The header packing has changed to make it 24 bits on all platforms,
which allows us to lower the EEPROM variable max size to 1024 bytes
again
 2012-02-13 16:22:52 +11:00
Andrew Tridgell 711cee9dfa fixed support for AP_PARAM_SPARE 
spare group elements are needed if we remove a group parameter

Doug Weibel e109992c12 Add a CLI setup action to reset the magnetometer offsets 
Since the magnetometer offsets are not available through the MAVLink parameter interface (since they are an AP_Var vector) this little feature allows them to be reset from the CLI.  Useful if you somehow get bad offsets or if you change magnetometer.  If you have a bad set of large offset values I have seen issues with the nulling algorithm have trouble converging to the proper values.  I have never seen it have trouble converging from 0/0/0, so this could be a useful feature from time to time.

Andrew Tridgell 817e7442bd baro: fixed an integer overflow issue at high altitudes

Andrew Tridgell f4490b62c7 DCM: prevent a segmentation fault when compass is not enabled 
when compass is disabled _compass is NULL
 2012-01-13 15:48:07 +11:00
Doug Weibel 622217357c Bug fix for compass. 
This is a fix for an interesting bug when a DCM matrix reset was added to the ground start.  This bug only showed up if (A) a ground start were performed after an air start or due to use of the "Calibrate Gryo" action, (B) if the current orientation were sufficiently different from 0/0/0, and (C.) if the particular magnetometer had sufficiently large offsets.  Why did resetting the DCM matrix to 0/0/0 pitch/roll/yaw at ground start cause a bug?  The magnetometer offset nulling determines the proper offsets for the magnetometer by comparing the observed change in the magnetic field vector with the expected change due to rotation as calculated from the rotation in the DCM matrix.  This comparison is made at 10Hz, and then filtered with a weight based on the amount of rotation to estimate the offsets. Normally it would take considerable time at normal in-flight rotation rates for the offset estimate to converge. 

If a DCM matrix reset occurs when the offset nulling algorithm is up and running, the algorithm sees the DCM reset as a instantaneous rotation, however the magnetic field vector did not change at all.  Under certain conditions the algorithm would interpret this as indicating that the offset(s) should be very large.  Since the "rotation" could also have been large the filter weighting would be large and it was possible for a large erroneous estimate of the offset(s) to be made based on this single (bad) data point.

To fix this bug methods were added to the compass object to start and stop the offset nulling algorithm.  Further, when the algorithm is started, it is set up to get fresh samples.  The DCM matrix reset method now calls these new methods to stop the offset nulling before resetting the matrix, and resume after the matrix has been reset.
