Andrew Tridgell a851c53de4 GPS: need pgmspace.h for _write_progstr_block() 2012-06-15 16:27:11 +10:00
Andrew Tridgell 70f18289c5 GPS: fixed auto-config of UBlox setup with no UBX messages 
if a UBlox is configured for NMEA only, with no UBX messages at all
then it would never trigger the GPS_AUTO detection. This adds a UBX
config message to the init strings that enables the NAV_SOL message
 2012-06-15 15:53:27 +10:00
Andrew Tridgell 1fe297ab63 FastSerial: added tx_pending() method 
this allows the caller to wait for the tx buffer to drain

want. It also supports setting the navigation engine type
 2012-06-10 16:34:13 +10:00
Andrew Tridgell 9c1ce9e1c5 FastSerial: avoid buffer re-allocation on re-open if possible 
we commonly re-open serial ports a lot in the AUTO GPS driver
 2012-06-09 07:43:22 +10:00
Andrew Tridgell cf4e56457b SITL: map() is a C++ function, so needs to be in C++ part of the header 
this fixes the ACM build
 2012-06-08 17:09:23 +10:00
Andrew Tridgell cbf477addd GPS: added debug code to the main GPS class 2012-06-08 16:42:03 +10:00
Andrew Tridgell a8bfc5d8e9 GPS: re-open the serial port with a 256 byte serial receive buffer 
this ensures all GPS parsers have a 256 byte buffer available
 2012-06-08 16:42:03 +10:00
Andrew Tridgell 296e651b30 GPS: fixed the UBLOX parser to handle unknown messages 
the parser was broken in several ways:

 1) when it received an unknown message it didn't update the ck_a and ck_b fields, so it
    thought the message had a bad checksum, which meant it got out of protocol sync

 2) the read() method would return false if the last message from the GPS was of an unknown type. 
    So we relied on the last msg always being one that we understand and want

 3) the parser considered any valid UBLOX message to be 'new data', whereas we only actually get 
    a new fix when we get box a new position and velned message

 4) the total message size per update is more than 128 bytes, but the serial port was opened 
    with only a 128 byte buffer, so we got corruption regularly
 2012-06-08 16:42:02 +10:00
Andrew Tridgell 9c2ba2e814 GPS: tidy up the auto gps test 2012-06-08 16:42:02 +10:00

 2012-06-02 16:13:23 +09:00
rmackay9 c3b1a79f6a 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 d9f124afbb RC_Channel.pde: fixed compile errors so that it actually works! 2012-06-02 14:00:44 +09:00
rmackay9 2a216ce900 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 c2d14a5cad 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

Andrew Tridgell ddfa06e857 SITL: fixed ChipErase() 
the loop never completed
 2012-05-23 21:15:45 +10:00
Andrew Tridgell 6e444f6b64 SITL: fixed build with new ChipErase() call 2012-05-23 17:33:33 +10:00
Andrew Tridgell fc73fd6531 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 f274df454a 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

rmackay9 357d6c2d9b 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 69bf5700cd IMU: expose IMU_PRODUCT_ID as EEPROM Variable

this will be used to avoid races in driver initialisation
 2012-05-01 12:06:54 +10:00
rmackay9 6e1798b104 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 ca8bc34c98 MAVLink: re-generated with new pygen

Adam M Rivera 3309dec205 AP_AHRS_DCM.cpp: Added comments that follow the new parse structure 2012-04-25 12:00:42 -05:00
Andrew Tridgell 89041c6996 sitl: support MAVLink 1.0 builds 2012-04-24 22:24:58 +10:00
Andrew Tridgell d11957718f 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 eb5bc964d8 MAVLink: one more define for MAVLink 1.0 compat 2012-04-24 19:54:20 +10:00
Andrew Tridgell 0753782c49 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 5c067d5a03 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 e8f8115a8f 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 2a3af369b6 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 f27d85cb8d 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 11a384a7ff AP_Motors - allow tail servo to be reversed. Closes ArduCopter issue #228 2012-04-21 23:07:57 +09:00
rmackay9 c45b124cbe 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 f18ee75b5c AP_OpticalFlow - updated test sketch to allow testing of APM2 version 2012-04-21 20:11:18 +09:00

Andrew Tridgell 8e90aeea4e 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 28833ed1d6 added missing #include 2012-04-09 14:32:54 +00:00

rmackay9 ef43da9b92 AP_Compass - changed parameter initialisation order to remove compiler warning 2012-04-09 17:37:02 +09:00
Andrew Tridgell 985c967bb9 MAVLink: imported new mavlink headers 
this adds local and remote radio noise levels
 2012-04-08 12:22:17 +10:00
rmackay9 53827f2e92 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 127a990509 AP_MotorsOcta - V Frame - test order fix spotted by David Wiens 2012-04-07 08:11:28 +09:00
rmackay9 f6e1509d05 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 1e20d7de88 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 7a8973eaf0 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 926211f0f0 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 b71877366e 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 1fd1a55fa6 MAVLink: import change to txbuf as a percentage 2012-04-02 11:18:53 +10:00
Andrew Tridgell 4ddeb82b26 MAVLink: imported new headers, with RADIO packet 2012-04-01 21:44:44 +10:00
Andrew Tridgell 0c445101ff 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 22ff8cb197 examples: fixed build of some examples with new AP_Declination code 2012-03-30 14:25:27 +11:00
Andrew Tridgell 504c53f746 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 927834106d 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 70d4280935 AP_Declination: added timing information to declination test 2012-03-30 14:25:27 +11:00
Andrew Tridgell 175352845c AP_Declination: fixed build under SITL 2012-03-30 14:25:27 +11:00
Adam M Rivera ca82350f17 AP_Declination_test: Updated test with better print messages. 2012-03-30 14:25:26 +11:00
Adam M Rivera 01b1e58f7d 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 23f6093f05 AP_Declination: Updated comments to reflect new LUT size. 2012-03-30 14:25:06 +11:00
Adam M Rivera 50791a8b0f 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 f35e447927 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 72b70c394c 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 076192db51 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 230ca1ddca 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 e0fa053c79 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 f66c6e16e4 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 d88b9e8ffc AP_Declination: Updated packed exception signs array. I had the signs packed incorrectly. 2012-03-30 14:21:57 +11:00
Adam M Rivera 036da88174 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 580b274bde 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 efefc3e4f4 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 0dcc4e8307 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 3a849771bc 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 370e56c00a 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 ae257ad42b 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 b549b88e5e 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 16deefce31 Compass: fixed a comment 2012-03-29 12:39:53 +11:00
Andrew Tridgell 17290836ef Compass: added some more comments 
explain the algorithm a bit more
 2012-03-29 12:39:53 +11:00
rmackay9 2ce597642e Filter - added FilterWithBuffer typedefs for int32t and uint32 for ease of use 2012-03-28 22:02:52 +09:00
rmackay9 90fcdeadfd 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 10c35e3769 SITL: add magnetic field noise to the simulated compass 2012-03-28 20:55:27 +11:00
Andrew Tridgell f4c1b6a3c6 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 b2d6db9479 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 9b95d2060a 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 a72d4b46b3 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 b5dbdab81e 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 2b2dbf2a7f 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 39fd24ed14 Filter - remove obsolete warning from comments re alloc/malloc dangers 2012-03-25 16:14:07 +09:00
rmackay9 2d65ec2874 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 d371862fd2 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 a6d66dc45b 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 f4d1295a4b AHRS: fixed build of AHRS example 2012-03-22 23:00:45 +11:00
Andrew Tridgell fe55a76335 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
 2012-03-21 10:43:48 +11:00
Andrew Tridgell 17fbb8ea26 Math: fixed the build of the eulers test in SITL 2012-03-21 10:41:55 +11:00
Andrew Tridgell 90c3d230d9 SITL: improve the simulated compass 
this implements a much more accurate model of a compass using matrix
rotations, instead of trying to calculate components directly
 2012-03-21 10:41:55 +11:00
rmackay9 24a471ff8f AC_PID - added more paranoid checking that imax is positive in constructor, operator() and load_gains methods 2012-03-20 11:51:15 +09:00
Andrew Tridgell 9f4becbacf AHRS: added AHRS specific MAVLink headers 2012-03-19 17:35:20 +11:00
Andrew Tridgell 9e6c18cca4 AHRS: added missing AP_AHRS.h 2012-03-19 17:35:20 +11:00
Andrew Tridgell 4f82134a5e DCM: use the new rotate() method from AP_Math 
this allows us to use a tested and optimised rotation method
 2012-03-19 17:29:02 +11:00
Andrew Tridgell 17f7292fe9 Math: added a test for the rotate() method 2012-03-19 17:29:02 +11:00
Andrew Tridgell c16b353ea7 Math: added rotate() method to Matrix3f 
this is the core method used to update the DCM matrix with a gyro
vector. Moving it to AP_Math allows us to have a test for it
 2012-03-19 17:29:02 +11:00
Andrew Tridgell 31e566475b Math: added zero() and identity() methods to Matrix3f 2012-03-19 17:29:02 +11:00

Andrew Tridgell 72a761170b Math: fixed build of eulers test on SITL 2012-03-19 17:29:02 +11:00
Andrew Tridgell 58a68c89d9 Math: added a function to combine standard rotations 
this will allow us to have an overall board rotation plus a per-sensor
rotation
 2012-03-19 17:29:02 +11:00

 2012-03-19 17:29:01 +11:00
Andrew Tridgell 55ed84526a MAVLink: rename DCM message to AHRS 2012-03-19 17:29:01 +11:00
rmackay9 01cc5fe938 AP_Baro - removed unnecessary 2 element average filtering of pressure (there is a 4 or 5 element average filter in arducopter code itself, two places is messy) 
- also removed unused _offset_press variable
 2012-03-18 15:18:05 +09:00
rmackay9 7560242721 AP_Baro - added average filter for temperature to replace broken filter 
- added average filter (for last two values) for raw pressure
        - changed some "long" to int32_t and "unsigned long" to uint32_t

thanks Justin!
 2012-03-13 13:27:45 +11:00
Andrew Tridgell 13dac4a93a DCM: adjust yaw kp constant down to 0.4 
this makes the time constant for compass errors closely match the
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 7daaadf776 Compass: fixed the order of rotations in the compass driver 
this should fix the massive heading issues that people have been
reporting. Please test!

Adam M Rivera fe8c896d69 AP_Declination: Added method set_initial_location 
This will set the declination based on lat/lon if the user has
not yet saved one to the EEPROM, OR if they have specified via the
config parameter that they want it to overwrite the declination every
3D fix.
