Jonathan Challinger 9cd98e79dd AHRS: normalise GA_b before computing error vector only if too large 
When GA_b is small the direction of the vector is unreliable, so
normalising can exacerbate the error in the direction

Andrew Tridgell 175b6d2606 AP_AnalogSource: fixed reporting of VCC 
the VCC pin number should not be converted

Andrew Tridgell 5f5ab9c07c AHRS: if we don't have gps correction enabled, zero the yaw correction 2012-07-20 17:21:04 +10:00
Andrew Tridgell c937738732 AHRS: allow the gps/accelerometers to control yaw when rolled 
this solves a problem with yaw estimation when at high roll angles,
when the compass code becomes ineffective

Amilcar Lucas 3de23220ed RC_Channel parameters: Fix a typo 2012-07-18 22:39:49 +02:00
Amilcar Lucas 22d2f9ea15 Support up to 7 aux servo outputs 2012-07-18 21:58:22 +02:00
rmackay9 e61cf0e1f9 AP_Mount: added set_manual_rc_channel and set_manual_rc_channel_function to allow input of pitch, roll and yaw controls from a regular RC_Channel (i.e. not RC_Channel_aux) 
For now, angles red in are always of the range -45 deg ~ 45 deg which is consistent with the existing arducopter implementation but should be improved to scale the pilot's input to the mount's actual range.

Amilcar Lucas 461098b289 Replace long with int32_t 2012-07-18 02:12:31 +02:00
Amilcar Lucas 724c5f6490 Use ascending order in the values 2012-07-18 02:11:49 +02:00
Amilcar Lucas 1da0ce20ce Improve parameter documentation, it still does not work, but is an improvement. 
I just do not understand why these parameters do not appear in Mission planner :(

Michael Oborne 9e4d118fdb Airspeed Library - fix param names. 
The Group definition give the start of the param name.
This way we can maintain multiple instances if required of the same library as options.

Andrew Tridgell feb456de56 Airspeed: Added AP_Airspeed sensor library 
this will allow an airspeed sensor object to be passed to AHRS for
dead reckoning

rmackay9 acef75319c AP_MotorsMatrix: small bug fix to limit checking on remove_motor call. Fix thanks to Michael Peschel! 2012-07-16 00:38:58 +09:00
rmackay9 669ffb5ef8 RC_Channel_aux: added enable_out method to help stop servos from moving before the mount has initialised. 
changed parameter names of "update_aux_servo_function" to make it more clear that any 4 servos can be passed in (not just servos 5~8).
Also allowed NULL servos to be passed in as parameters because we only need 3 in ArduCopter.
 2012-07-15 16:28:53 +09:00
rmackay9 5616b1769b AP_Camera: changed "int" to "int16_t" and "long" to "int32_t" here and there. 2012-07-15 16:26:12 +09:00
Andreas M. Antonopoulos c73f7ef3ab AP_Limits library, provides modular "limits" such as altitude and geo-fencing. 2012-07-14 19:26:17 -07:00

Robert Lefebvre ed235a3924 Change to prevent Tricopter servos from going hard-over during Disarmed state. 
Believe this was an oversight when the change to AP_Motors went in.
 2012-07-13 23:12:26 -04:00
Robert Lefebvre 8ce9aae2f7 Instituting Yaw Differential on Multirotors. Intent is to stop "rise on yaw input". 
Since motors with increasing speed due to yaw input seem to generate more thrust that motors that slow lose thrust, thus net thrust goes up, causing copter to climb.
Values are a guesstimate, proven out by test flying.  This could probably become a parameter.

Andreas M. Antonopoulos d4a0cb5db1 Added Michael Pursifull's Maxsonar HRLV model support 2012-07-11 18:46:47 -07:00

rmackay9 4dd4c95d5c AP_AnalogSource_Arduino: fix to allow analog port to be read to be specified as a "channel" (i.e. A0) 
Also fixed example range finder sketch to work with interrupt enabled AP_AnalogSource_Arduino class
 2012-07-11 21:19:17 +09:00

Amilcar Lucas bccb07cbd0 Allow mount control when no AHRS exists 
Allow mount control on non stabilized axes
 2012-07-11 00:06:26 +02:00

Andrew Tridgell 165604a55c AHRS: fixed HIL build 2012-07-10 18:02:05 +10:00
Andrew Tridgell 0f9fb2c64b AHRS: added AHRS_GPS_GAIN parameter

doing centripetal correction in DCM
 2012-07-10 16:22:48 +10:00
Andrew Tridgell e1725e9ea5 AP_Param: added some docs on the eeprom header format 2012-07-10 14:03:49 +10:00
Craig Elder 6d3fdfc03a DataFlash: The current method for checking if chip erase worked is producing false positives. We are forcing the block erase until we have a deterministic test method. 2012-07-09 15:23:35 -07:00
Amilcar Lucas af338939be RC_Channel: Improve documentation 2012-07-07 21:57:30 +02:00
Amilcar Lucas 46552b4222 AP_Mount: Fix radians/degrees scaling regressions 
Rename calculate() into stabilize()
Implement MAV_MOUNT_MODE_RC_TARGETING initialization
Document to make sure this radians/degrees mess up does not happen again

Andrew Tridgell d755fedc26 AnalogSource: prevent a division by zero on zero ADC data 2012-07-06 19:59:18 +10:00
Andrew Tridgell f6d7d1bc59 APM: changed PID library to do automatic deltat calculation 
this fixes a problem with the HDNG2RLL PID, which was using the wrong
time base and prevents similar bugs from happening in the future
 2012-07-06 19:59:18 +10:00
Andrew Tridgell f501503eb0 AP_Baro: improved barometer averaging 
this changes the barometer calculations to floating point. On a MS5611
this is actually about twice as fast as the previous 64 bit
calculations, but gains us more accuracy as we are able to take
advantage of sub-bit precision when we average over 8 samples.
 2012-07-06 15:11:30 +10:00
Andrew Tridgell 520d762382 Filter: split the DerivativeFilter steps into update() and slope() 
this allows us to apply new data at a different rate than we calculate
the slope.
 2012-07-06 15:11:30 +10:00
Andrew Tridgell 3c7e521f70 AP_Baro: update MS5611 test to use baro library altitude 2012-07-06 15:11:30 +10:00
Andrew Tridgell 302696951a AHRS: make the yaw independent drift correction optional and disable 
the new correction algorithm copes poorly with gyro drift, leading to
signification attitude errors in the face of drift
 2012-07-06 15:11:30 +10:00
Andrew Tridgell 8c5ef3e60f AHRS: only enable barometer for AHRS if it is smooth enough 
if we used less than 5 samples to compute the pressure then don't use
it for climb rate
 2012-07-05 16:29:21 +10:00
Andrew Tridgell ec0995eea1 SITL: lower baro noise a bit 2012-07-05 16:29:21 +10:00

Andrew Tridgell d29b6ce0a8 SITL: run the HIL barometer at 80Hz to match APM2 2012-07-05 16:29:21 +10:00
Andrew Tridgell 209136386b AP_Baro: added get_pressure_samples() interface 
this returns how many samples were used to calculate the last pressure

Andrew Tridgell 1a42b10255 Filter: fixed typo in 9 point DerivativeFilter 2012-07-05 16:29:20 +10:00
Andrew Tridgell 185c6e5b32 AP_Baro: change to a 7 point DerivativeFilter for climb rate 2012-07-05 13:00:47 +10:00
