Andrew Tridgell fb23c617fa 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 a05eeab55e 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 d03b11092b SITL: separate out drift speed and drift level 2012-03-10 10:34:28 +11:00
Andrew Tridgell 71d3847bfc 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 61ebcfe9fe 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 de32c3bc31 AP_Math: added a .zero() method to Vector3f 2012-03-10 10:34:28 +11:00
Andrew Tridgell a0e2e69431 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 37ab76c9e6 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 d2a969ee95 SITL: push noise level to 2.0 for DCM testing 2012-03-10 10:34:27 +11:00
Andrew Tridgell 79b8ddc236 DCM: added a small amount of accel smoothing to update_DCM_fast() 2012-03-10 10:34:27 +11:00
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
 2012-03-10 10:34:27 +11:00
Andrew Tridgell a78b00513b 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 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 
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 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
 2012-03-02 15:48:27 +11:00
Jason Short 59e1d43f60 Updated fastPWM to 490Hz 2012-02-29 22:17:38 -08:00
Pat Hickey 8fa559930f AP_Param: nested group recursion into next_group disableable by macro 
* c.f. 0251932c81fe7eb, e5515bb6ef82
 2012-02-29 19:48:43 -08:00
Pat Hickey 8b3d013294 AP_Param: One more nexted group recursion disableable by macro 
* c.f. e5515bb6ef82

rmackay9 0311b70004 AP_Baro - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:46:29 +09:00
rmackay9 64f9f1d92e AP_Compass - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:45:49 +09:00
rmackay9 7c1d1b45a7 AP_DCM - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:45:26 +09:00
rmackay9 3cbd172ea9 RC_Channel - fixed small compiler warning 2012-02-29 22:44:29 +09:00
rmackay9 ced49f7d01 AP_ADC - removed small compiler warning 2012-02-29 22:43:46 +09:00
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
rmackay9 5b89c65d9c Filter - updated example sketch to use modified library 2012-02-28 21:01:35 +09:00
rmackay9 d17a015df1 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 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 
scale the noise based on the period of the motors
 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 
add comments on the arguments, and name them in a clearer way
 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!) 
increased maximum sample buffer size from 6 to 10
 2012-02-26 17:17:46 +09:00
rmackay9 3f0d27ec87 ModeFilter - remove older ModeFilter library (new library is now in Filter directory) 2012-02-26 15:36:23 +09:00
rmackay9 00a1b5cd53 AP_RangeFinder - cut over to use new ModeFilter from Filter library 2012-02-26 15:34:50 +09:00
