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 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 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 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

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
 2012-03-18 01:06:02 +09:00

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.

Andrew Tridgell 0da64e98f8 Compass: don't save the orientation to EEPROM 
there is no point in saving this, the value is only configurable at
compile time for now, and is always set
 2012-03-11 15:37:07 +11:00
Andrew Tridgell 0ec9857689 Math: any euler angle with pitch > 90 is invalid

Andrew Tridgell 289c64c0b9 Math: added vector3.rotate() and matrix3.rotation() methods 
these operate on a "enum Rotation" which defines a set of standard
rotations. These are much faster than our previous method, plus use
less memory
 2012-03-11 15:37:07 +11:00

 2012-03-10 10:34:33 +11:00
Andrew Tridgell bcb7196680 IMU: added get_gyro_drift_rate() interface

Andrew Tridgell 4d65cda0ea AP_Math: added quaternion->matrix and earth frame routines 
this will be used for 3d acceleration
 2012-03-10 10:34:31 +11:00
Andrew Tridgell 8abbbe5713 AP_Math: better way of handling safe_sqrt() 
better to test the result, than predict it
 2012-03-10 10:34:31 +11:00
Andrew Tridgell ccada2e9c2 SITL: avoid parent pid code on cygwin 
this causes problems on windows
 2012-03-10 10:34:31 +11:00
Andrew Tridgell 3666476bcb SITL: prevent nested timer interrupts 2012-03-10 10:34:31 +11:00

this is for Michael to run
 2012-03-10 10:34:30 +11:00
Andrew Tridgell 1ec4c0777c Math: added comment on quaternion constructor 2012-03-10 10:34:30 +11:00

Andrew Tridgell 066a513758 Quaternion: added more numerical safety in the quaternion code 
prevent infinities from creeping in and prevent large drift changes
 2012-03-10 10:34:30 +11:00
Andrew Tridgell c7d5f06b21 AP_Math: added quaternion helper functions and a test suite 2012-03-10 10:34:30 +11:00
Andrew Tridgell f70dfe440d 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
 2012-03-10 10:34:30 +11:00
Andrew Tridgell 47ddd4dfdd SITL: disable interrupts during register updates 
this may prevent bogus mode channel reads
 2012-03-10 10:34:30 +11:00
Andrew Tridgell 7256652de5 Quaternion: use GPS to correct for linear acceleration 
this gives much better pitch estimates. We should do this with the
airspeed sensor if available.
 2012-03-10 10:34:30 +11:00
Andrew Tridgell c7ef72cf28 Quaternion: don't update if we have a very long deltat 
this can be caused by stopping the system in a debugger
 2012-03-10 10:34:30 +11:00
Andrew Tridgell 6d356b6c6e Compass: fixed last_update time for HIL compass 2012-03-10 10:34:30 +11:00
Andrew Tridgell ebc55bb494 RC: disable interrupts when reading the RC registers 
this prevents getting bogus values which could cause a flight mode
change
 2012-03-10 10:34:30 +11:00
Andrew Tridgell 57f67ca6e3 GPS: added an acceleration estimate to the GPS driver 
This uses the GPS ground speed to estimate acceleration

Andrew Tridgell cc887949c9 AP_IMU: improved the gyro calibration code 
this should give a much more accurate result
 2012-03-10 10:34:29 +11:00
Andrew Tridgell ffa6786697 Quaternion: drop the gyro drift rates down 
this should allow us to cope with noise more readily
 2012-03-10 10:34:29 +11:00
Andrew Tridgell bee4bd9474 DCM: fixed bug in accel averaging 
sorry Randy!

Andrew Tridgell c369d9f60a AP_Quaternion: added DCM compatibility interfaces 
useful for getting the code going quickly
 2012-03-10 10:34:29 +11:00
Andrew Tridgell 6138f31cec AP_IMU: added new_data_available() interface 2012-03-10 10:34:29 +11:00

Andrew Tridgell c80ec9a55c AP_ADC: added new_data_available() interface 
returns true if more samples are available
 2012-03-10 10:34:28 +11:00
Andrew Tridgell c8a459ab0d fixed deltat in quaternion 2012-03-10 10:34:28 +11:00
Andrew Tridgell a791224d07 SITL: make SITL not depend on DCM 2012-03-10 10:34:28 +11:00
Andrew Tridgell 74eef7018a Quaternion: added an AP_Quaternion library 
this is for experimenting with the Madgwick quaternion system, to see
if it is more or less noise sensitive than DCM
 2012-03-10 10:34:28 +11:00
Andrew Tridgell fd2a24f8ed SITL: reduce the simulated compass offsets 
this was causing us problems in getting DCM right
 2012-03-10 10:34:28 +11:00
Andrew Tridgell bddc6ba241 SITL: separate out drift speed and drift level 2012-03-10 10:34:28 +11:00
Andrew Tridgell 25cad09746 SITL: added a drift_level multiplier 
this makes it easier to experiment with different gyro drift levels
 2012-03-10 10:34:28 +11:00
Andrew Tridgell b11b571778 DCM: fixed the averaging of accel values for update_DCM_fast() 
this should improve drift correction for ArduCopter
 2012-03-10 10:34:28 +11:00
Andrew Tridgell 145fc91701 AP_Math: added a .zero() method to Vector3f 2012-03-10 10:34:28 +11:00
Andrew Tridgell ae51173656 SITL: fixed delay() to account for signal interrupions 
when a timer went off we stopped the delay() code
 2012-03-10 10:34:28 +11:00
Andrew Tridgell fe173227de DCM_Test: fixed example code to work with SITL 
this also fixes the compass setup
 2012-03-10 10:34:27 +11:00
Andrew Tridgell 8424609924 SITL: push noise level to 2.0 for DCM testing 2012-03-10 10:34:27 +11:00
Andrew Tridgell 6ba6e11e7b DCM: added a small amount of accel smoothing to update_DCM_fast() 2012-03-10 10:34:27 +11:00
Andrew Tridgell 3b1782f369 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
 2012-03-10 10:34:27 +11:00
Andrew Tridgell 4031320f7c DCM: added a small amount of gyro and accel smoothing 
possibly not needed, but convenient to be able to test with different
values
 2012-03-10 10:34:27 +11:00
Andrew Tridgell 94d0236b97 DCM: added reporting interfaces for DCM state 2012-03-10 10:34:27 +11:00
Andrew Tridgell 772c30ba86 SITL: added sitl_simstate_send() 
used to report simulator state in logs
 2012-03-10 10:34:27 +11:00
Andrew Tridgell 9df332f0ae MAVLink: import new message types DCM, HWSTATUS and SIMSTATE 2012-03-10 10:34:27 +11:00
Andrew Tridgell cc8278c1ac 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.
 2012-03-10 10:34:27 +11:00
Jason Short 486c56ce41 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 e57b91c2e2 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 6c3cf9ad5b AP_RC - removed unused library 2012-03-04 18:21:52 +09:00
Andrew Tridgell 73dafe537e SITL: use the new noise model 
use the new noise model at a low level for master until we sort out
DCM noise handling
 2012-03-02 18:31:07 +11:00
Andrew Tridgell 5f749325f0 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 f4329d2680 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 1e8d98cdda I2C: added lockup_count() interface 
used for reporting I2C problems
 2012-03-02 15:48:27 +11:00
Andrew Tridgell 37275d229d SITL: implement cli()/sei() properly for desktop build 
this disables simulated hardware interrupts during critical sections
 2012-03-02 15:48:27 +11:00
Jason Short 41b435a487 Updated fastPWM to 490Hz 2012-02-29 22:17:38 -08:00
Pat Hickey 337af0c7a2 AP_Param: nested group recursion into next_group disableable by macro

rmackay9 fa34ac076e AP_Compass - fixed compile warning 2012-02-29 22:57:35 +09:00
rmackay9 d81c951849 AP_Baro - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:46:29 +09:00

rmackay9 c444cdb3f4 AP_ADC - removed small compiler warning 2012-02-29 22:43:46 +09:00
Pat Hickey eac8b66385 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 2b6a10d18b AP_RangeFinder - changed example sketch to work with new Filter library 2012-02-28 21:02:10 +09:00
rmackay9 033347f8ee Filter - updated example sketch to use modified library 2012-02-28 21:01:35 +09:00
rmackay9 645fda2fb2 Filter - added AverageFilter, removed SumFilter 
added FilterWithBuffer to allow removal of malloc/free without losing ability to pass around filter objects
 2012-02-28 21:01:11 +09:00
Andrew Tridgell cb52b6c6d9 AP_Param: show numerical value in eeprom dump utility 2012-02-28 09:43:49 +11:00
Andrew Tridgell a432232db9 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 39797c6f33 SITL: simulate noise on each ADC channel separately 
scale the noise based on the period of the motors
 2012-02-28 09:43:49 +11:00
Andrew Tridgell efe5c0142c 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 cd4fcb694e IMU: removed unused accel_filtered code 2012-02-28 09:43:49 +11:00
Andrew Tridgell 87a6d97f7b 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 fa443bd928 AP_Param: make the templating code a bit clearer 
add comments on the arguments, and name them in a clearer way
 2012-02-27 10:54:33 +11:00
Andrew Tridgell eb35e0e8ac 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!
 2012-02-26 22:24:45 +11:00
rmackay9 297d2ae457 ModeFilter - corrected shadowed variable compiler warning for drop_high_sample 2012-02-26 17:57:28 +09:00
rmackay9 b9b88ba237 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 f53ff8de97 Filter - removed shadowing of variables in constructors for Filter, ModeFilter and SumFilter (sorry tridge!) 
increased maximum sample buffer size from 6 to 10
 2012-02-26 17:17:46 +09:00
rmackay9 74f7d7a1c0 ModeFilter - remove older ModeFilter library (new library is now in Filter directory) 2012-02-26 15:36:23 +09:00
rmackay9 f264e29814 AP_RangeFinder - cut over to use new ModeFilter from Filter library 2012-02-26 15:34:50 +09:00

rmackay9 952e5d7bbc AP_Mount - #include FastSerial first to allow it to compile under Arduino 1.0 2012-02-26 15:31:56 +09:00
Andrew Tridgell d0a6359b37 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 900388a85a 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 f59297d7a7 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 eb71b26d3f DCM: use the new use_for_yaw() compass method 2012-02-25 14:51:09 +11:00
Andrew Tridgell 664622523d 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 f10097a6d5 AP_Param: added some comments on AP_Vector3f handling 2012-02-25 11:37:20 +11:00
Andrew Tridgell 5e2fbdb6cf 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 2e9105c68a 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 d6bfceef7c 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 54aa8297af libs: removed unused library GPS_IMU 2012-02-25 11:37:20 +11:00
Andrew Tridgell 185ab5aea9 libs: removed unusued library GCS_SIMPLE 2012-02-25 11:37:20 +11:00
Andrew Tridgell 55e33c3359 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 ab8cc3d478 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 ddeda1c367 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 06f37aad75 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 16ed8bc8f6 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 c354879f1f 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 17d16bc8c6 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 bad653f230 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 c8e6d03c67 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 502fbf6e17 AP_Math: added a safe_asin() function 
this adds range checking to asin()
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 17170da96e AP_Math: added is_nan() methods to vector3f and matrix3f 2012-02-24 11:52:55 +11:00
Jason Short b094f6ce52 added set integrator 2012-02-23 09:38:08 -08:00
Andrew Tridgell ef90f336d3 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 57ffd00b69 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 2bb58db3f7 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 156d98cb9f 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 53b87229ff AP_Param: added ParamToken type for variable list traversal 2012-02-19 17:05:28 +11:00
Jason Short 1e37a0ec17 added a limit to range output 2012-02-18 21:08:17 -08:00
Randy Mackay 33aa6fe13b 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 9793d04ed1 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 d52cb7e574 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

justinbeech 62b104cbfa 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.

Andrew Tridgell f2a6a31645 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,

Doug Weibel e22a83eec0 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.

Doug Weibel 9846822748 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.

Andrew Tridgell 977326e991 dataflash: reworked classes to move most code to parent class 
this moves all the non-hardware specific code to the parent
DataFlash_Class class, keeping the hw specific code much smaller and

This should prevent discrepancies creeping in between APM1 and APM2
support again

 2011-12-17 07:29:09 +11:00
Andrew Tridgell f6f808357c removed AperiodicProcess code 
this code was never being used, and was more complex than it was

Andrew Tridgell 9591317dbc ADC: added an enable_channel() API 
enable_channel() must be used before the Ch6() method is called to
enable gathering of data on the required channels
 2011-12-16 20:09:40 +11:00
Andrew Tridgell c41e7c505b timer: enable interrupts during timer processing 
this prevents us losing serial bytes when we call sensor drivers that
take more than 100usec to read.

We also prevent timer recursion by re-enabling the timer after all
callbacks are complete
 2011-12-16 20:09:38 +11:00
Andrew Tridgell 09947dace1 ADC: only read channels that are actually being used 
on the APM2 we usually use none of the ADC channels, although we may
use the airspeed sensor. This change means we detect which channels
are being read, and only do the SPI transfers for those ones. That
saves us about 100usec per timer interrupt (ie. about 10% of our CPU)
 2011-12-16 20:09:35 +11:00

Pat Hickey d6a8440ef2 APM_RC_APM2: Remove OutputCh from ::Init() 
* These calls were off by one anyway, by using the channel numbers

 2011-12-15 13:47:43 -08:00

Andrew Tridgell 92e0e929a4 AP_Common: replace strlcat_P() with a C implementation 
the one in the Arduino libc was giving us bogus results on one
machine, and is suspect. We couldn't spot what is wrong in the
assembler, but replacing the implementation with a C one fixes the
bug, so we replaced it
 2011-11-26 17:02:56 +11:00
Andrew Tridgell c9b0b384f7 desktop: added framerate and initial height code

the purple support is still a work in progress, but the APM1 support
should be fine
 2011-11-25 20:00:16 -08:00
Pat Hickey a159669cee build: added jtag-program make target 
useful for when you have hosed your USB
 2011-11-25 20:00:16 -08:00
Pat Hickey e53bcba4d9 purple: rework AP_IMU library to use AP_IntertialSensor library 
the AP_IMU keeps the handling of the calibration, but most of the real
work happens in the lower level AP_IntertialSensor library
 2011-11-25 20:00:16 -08:00
Pat Hickey 82b48784ef purple: added AP_InertialSensor library 
this abstracts the way of getting inertial sensor (gyro and
accelerometer) data for the APM1 and purple hardware. The Oilpan code
is based closely on the old APM1 code
 2011-11-25 20:00:16 -08:00
Pat Hickey c9f7618ccc purple: rework the RC_Channel library for the APM_RC changes 2011-11-25 20:00:16 -08:00
Pat Hickey f36ded2854 RangeFinder: rework to use AnalogSource library 
this removes the hacks that check for the ADC object, and instead
choose the method of getting the analog sonar value via the
AnalogSource API
 2011-11-25 20:00:16 -08:00
Pat Hickey 0c0a1b1dcc purple: Added AnalogSource library 
this library abstracts out the way of getting an analog value. If the
ADC library is being used then it calls the ADC Ch() method, otherwise
it calls analogRead()
 2011-11-25 20:00:16 -08:00
Pat Hickey 017f121566 AP_ADC: rework ADC library to use PeriodicProcess and ISR_Register 
this makes it possible to build the ADC library when another driver
may also want that interrupt
 2011-11-25 20:00:16 -08:00
Pat Hickey d288b8870d purple: added PeriodicProcess library 
this library provides a clean API for drivers to request periodic
timer driven calls at whatever rate they need
 2011-11-25 20:00:16 -08:00
Pat Hickey 1daadb5068 purple: added ISR_Registry() library 
this allows libraries to register interrupt handlers, so multiple
components can use the same hardware level interrupt
 2011-11-25 20:00:16 -08:00
Pat Hickey 36346fd86b purple: rework APM_RC library for purple hardware 
this splits the APM_RC class into instances for purple and APM1, and
adds example sketches for both
 2011-11-25 20:00:16 -08:00
Pat Hickey 2d8ce38aeb barometer: add purple_hardware option to Init() 
this allows selection of right hardware at Init() time
 2011-11-25 20:00:15 -08:00
