Andrew Tridgell	a7b9aff79f	AP_Baro: the DerivativeFilter now handles duplicate data ... this saves a few bytes of memory	2012-08-08 12:07:36 +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	185c6e5b32	AP_Baro: change to a 7 point DerivativeFilter for climb rate	2012-07-05 13:00:47 +10:00
Andrew Tridgell	f9fc7aafe7	AP_Baro: use DerivativeFilter in barometer climb rate	2012-07-05 13:00:46 +10:00
Andrew Tridgell	5bccfbd94c	Barometer: fixed airstart for APM ... we need to re-load the ground pressure and temperature from eeprom on and airstart	2012-06-27 16:01:50 +10:00
Andrew Tridgell	c387edd74c	Baro: added get_altitude() and get_climb_rate() interfaces ... this allows the barometer driver to calibrate and return altitude and climb rate values. This will be used by the AHRS drift correction code for vertical velocity The climb rate uses a 5 point average filter	2012-06-27 16:01:50 +10:00
