Author	SHA1	Message	Date
Andrew Tridgell	209136386b	AP_Baro: added get_pressure_samples() interface ... this returns how many samples were used to calculate the last pressure	13 years ago
Andrew Tridgell	185c6e5b32	AP_Baro: change to a 7 point DerivativeFilter for climb rate	13 years ago
Andrew Tridgell	f9fc7aafe7	AP_Baro: use DerivativeFilter in barometer climb rate	13 years ago
Andrew Tridgell	9f8703274c	AP_Baro: show climb rate in baro test sketch	13 years ago
Andrew Tridgell	057eb5e6f6	Baro: average over all pressure/temperature samples on MS5611 ... this allows us to use the MS5611 barometer at its full 100Hz sample rate (80Hz for pressure, 20Hz for temperature). The pressure and temperature values are averaged between reads without adding any latency. Previously the driver would throw away values between readings This also fixes a race condition in reading from the SPI bus that could lead to bad values from the barometer	13 years ago
Andrew Tridgell	f70cd71791	Baro: fixed build of MS5611 test code	13 years ago
Andrew Tridgell	5bccfbd94c	Barometer: fixed airstart for APM ... we need to re-load the ground pressure and temperature from eeprom on and airstart	13 years ago
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	13 years ago
rmackay9	5c9dc00ae2	AP_Baro: fixed comment to clarify that every-other call updates temperature or pressure	13 years ago
Andrew Tridgell	88b2139d91	Baro: added suspend/resume on init	13 years ago
rmackay9	2d65ec2874	AP_Baro - change data type size of temperature's average filter to int32_t (was int16_t)	13 years ago
rmackay9	01cc5fe938	AP_Baro - removed unnecessary 2 element average filtering of pressure (there is a 4 or 5 element average filter in arducopter code itself, two places is messy) ... - also removed unused _offset_press variable	13 years ago
rmackay9	7560242721	AP_Baro - added average filter for temperature to replace broken filter ... - added average filter (for last two values) for raw pressure - changed some "long" to int32_t and "unsigned long" to uint32_t	13 years ago
Jason Short	486c56ce41	Consolidated Barometer pressure sensing to a single filter based on Randy's new filter class.	13 years ago
Jason Short	e57b91c2e2	Updated on Barometer - increased the Temp filtering and decreased the pressure filtering to and get less temp noise, faster response from pressure. I'm filtering the Climb rate differently now, so this higher pressure noise should not hurt the derivative calcs at all now.	13 years ago
rmackay9	d81c951849	AP_Baro - fixed small compiler warning to do with order of parameters in constructor	13 years ago
justinbeech	62b104cbfa	Found free extra 256 bytes of RAM eliminate _clz use from libgcc ... Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment. The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz The _clz table gets pulled in if you do 64 bit division. This tiny change is the only place that we do long long division. Changing to a shift saves 256 bytes of ram.	13 years ago
Jason Short	026e4a6567	change constant to float 44330.0	13 years ago
Andrew Tridgell	804332c340	AP_Baro: fixed some signed/unsigned warnings ... and a potential bug on timer wrap	13 years ago
justinbeech	69f1613f2c	Uncommented cold temp compensation after testing. Fixed read throttle so read rate ends up nailing 100hz, not 90hz. minor commenting improvements.	13 years ago
Randy Mackay	b7ce7bfe18	Arduino 1.0 - small fix to make AP_Baro_MS5611_test.pde compile under Arduino 1.0	13 years ago
Randy Mackay	ed19c25a97	Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h". ... Modified FastSerial's write function to return size_t (number of bytes written).	13 years ago
Andrew Tridgell	897d9a1c0b	baro: fixed an integer overflow issue at high altitudes ... the averaging array was using 16 bit numbers, but we are storing numbers with 19 significant bits. That caused overflow at high altitude, and some very interesting altitude graphs! Thanks to Michael Oborne for spotting this in a log	13 years ago
Andrew Tridgell	9fb3b13af3	AP_Baro: when I2c fails, don't retry for 1s	13 years ago
Andrew Tridgell	074fd31506	Baro: fixed MS5611 example sketch	13 years ago
Andrew Tridgell	f871235480	Baro: show timing in baro test	13 years ago

Andrew Tridgell	e7720254dd	AP_Baro: update MS5611 driver for new ap_proceduce prototype ... this saves calling millis() quite so often	13 years ago
Andrew Tridgell	bb0f179495	AP_Baro: fixed temperature on MS5611 ... this caused a 2x scaling of altitude	13 years ago
Andrew Tridgell	3648c81dd9	barometer: fixed HIL barometer build	13 years ago
