Pat Hickey 8a0c6eba78 AP_IMU_INS: Eliminate init_accel from cold start. 
* Bug reported by Jason, 10 Dec 11
 2011-12-10 13:00:54 -08:00
Andrew Tridgell 1a8a1973a1 AP_IMU: fixed shim driver prototype 2011-11-25 20:00:18 -08:00
Pat Hickey 433caaedc0 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

Jason Short cf59e8ad82 Merge branch 'master' of https://code.google.com/p/ardupilot-mega 2011-09-30 18:40:40 -07:00
Jason Short 9a4bd31a8b Minimized the accel_filtered vector to be faster and more accurate. 
Made the Filter include the Accels and moved from 8 to 4 terms in the filter

James Goppert ac3e73f5c0 Optional recursion added. 2011-09-30 17:17:51 -04:00
James Goppert 112d5e9531 Improvements to cmake. 2011-09-29 21:23:26 -04:00
James Goppert 3a00ceb593 Added ArduBoat/ ArduRover/ and APO library. 2011-09-29 14:12:15 -04:00
Andrew Tridgell 1c5e8f0381 change ADC sample rate to 1kHz 
this costs us about 9% of our CPU, but should make aliasing much less
of a problem.

Andrew Tridgell bb35fdec10 IMU: re-work the IMU library to take advantage of the ADC Ch6() call 
This changes the IMU code to read 6 synchronised ADC channels at one
time, giving us matching values, and exposing the exact averaging time
to callers

tridge60@gmail.com 28cf3dfc79 IMU: added delay callback hooks to IMU initialisation 
this allows the imu init() call to use a custom replacement for
delay(), which will allow for the processing of MAVLink packets during
IMU initialisation

DrZiplok c1d97878a5 Implement an abstract IMU class. 
Refactor the existing AP_IMU as AP_IMU_Oilpan (this will require changes in other projects TBD).

Add a shim IMU class for use by e.g. HIL protocol handlers.

This paves the way for a better handling of HIL_MODE_SENSORS as well as the mooted SPI-based oilpan IMU.
