76736792f8 SITL: disable interrupts during register updates 
this may prevent bogus mode channel reads
 2012-03-10 10:34:30 +11:00
Andrew Tridgell
e445a455d0 Quaternion: use GPS to correct for linear acceleration 
this gives much better pitch estimates. We should do this with the
airspeed sensor if available.

1ea1b500a6 Quaternion: don't update if we have a very long deltat 
this can be caused by stopping the system in a debugger

2969e16f7d RC: disable interrupts when reading the RC registers 
this prevents getting bogus values which could cause a flight mode
change

this should give a much more accurate result
 2012-03-10 10:34:29 +11:00

353f9e613f SITL: make SITL not depend on DCM 2012-03-10 10:34:28 +11:00
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
a54d6f744e HWSTATUS: if we don't know the voltage, report it as zero 
this will tell us if board_voltage() is really working
 2012-03-10 10:34:28 +11:00
Andrew Tridgell
9393b21a8d ACM: adjust yaw drift correction constants 
this should give the compass a bit more authority
 2012-03-10 10:34:28 +11:00
Andrew Tridgell
8e162ec35b APM: fixed reset of control switch when short_fs_action is disabled 
When FS_SHORT_ACTN is 0, we should not re-read the control switch
unless we changed mode on the initial short fs action
 2012-03-10 10:34:28 +11:00
Andrew Tridgell

 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

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

79b8ddc236 DCM: added a small amount of accel smoothing to update_DCM_fast() 2012-03-10 10:34:27 +11:00
Andrew Tridgell
b07a3eb966 ACM: added SIMSTATE, DCM and HWSTATUS messages to ACM 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

Andrew Tridgell

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.
