Andrew Tridgell 2a70138ad1 INS: fixed raw accel offset for APM1 
we now get reasonable offset values
 2012-11-20 18:32:27 +11:00
Andrew Tridgell f2744f8ff7 INS: use vector subtraction to make code clearer 2012-11-20 18:32:27 +11:00
rmackay9 317b719a62 AP_InertialSensor: correct typo to datasheet's filename 2012-11-20 00:37:42 +09:00
rmackay9 e2b1cb7e8d AP_InertialSensor: changes after review with Tridge. 
sanity checking added to accelerometer calibration routine.
user feedback is sent using gcs_send_text_fmt instead of Serial.printf.
moved ins parameters to new eeprom number to avoid conflicts with older parameters.
other small changes including renaming of functions and parameters.

rmackay9 e835cef181 AP_InertialSensor: merge in calibration features from IMU library 
add gauss-newton method of accelerometer calibration
 2012-11-07 19:20:27 +09:00
rmackay9 1cd4b08fac AP_AHRS: added scheduler parameter to init 
Required by the AP_AHRS_MPU6000 class which needs to disable timed processes that could interfere with it's communication with the mpu6000
 2012-09-29 13:51:21 +09:00
rmackay9 4bca609b9f AP_InertialSensor_MPU6000: replaced _cs_pin parameter with #define and saved 1 byte of memory 
Updated ArduCopter, ArduPlane and example sketches in AP_InertialSensor, AP_IMU and AP_AHRS libraries because they no longer need to pass in cs_pin to the constructor
 2012-09-28 19:21:59 +09:00

rmackay9 d8142c2351 AP_InertialSensor_MPU6000: move _last_sample_time_micros to capture time data_interrupt was called 2012-09-10 11:38:08 +09:00
rmackay9 bd3eab7c0f AP_InertialSensor: use AP_TimerProcess's queue_process to run read from MPU6000 after any currently running processes complete 2012-09-10 11:38:03 +09:00
rmackay9 3901387c8d AP_InertialSensor: changed read of sensor from MPU6000 to happen immediately 
This reduces the delay between when data arrives and when it is used
by up to 1ms.

Added num_samples_available method to all InertialSensors to allow
main loop timing to be synced with sensors.
 2012-09-10 11:37:33 +09:00
rmackay9 67252c8a9b AP_InertialSensor_MPU6000: bug fix. DMP was being enabled by default so although the results were not being used, this caused a delay in the main loop 2012-08-28 17:02:07 +09:00
