Andrew Tridgell f70cd71791 Baro: fixed build of MS5611 test code 2012-07-02 13:44:53 +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

rmackay9 5c9dc00ae2 AP_Baro: fixed comment to clarify that every-other call updates temperature or pressure 2012-06-03 17:31:17 +09:00
Andrew Tridgell 88b2139d91 Baro: added suspend/resume on init 2012-05-01 12:06:54 +10:00
rmackay9 2d65ec2874 AP_Baro - change data type size of temperature's average filter to int32_t (was int16_t) 2012-03-24 23:21:11 +09:00
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
 2012-03-18 15:18:05 +09:00
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

Jason Short 486c56ce41 Consolidated Barometer pressure sensing to a single filter based on Randy's new filter class. 2012-03-08 23:13:04 -08:00
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. 2012-03-06 20:55:35 -08:00
rmackay9 d81c951849 AP_Baro - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:46:29 +09:00
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.

Andrew Tridgell 804332c340 AP_Baro: fixed some signed/unsigned warnings 
and a potential bug on timer wrap
 2012-02-13 21:39:18 +11:00
justinbeech 69f1613f2c Uncommented cold temp compensation after testing. Fixed read throttle so read rate ends up nailing 100hz, not 90hz. minor commenting improvements. 2012-02-13 00:00:06 +00:00
Randy Mackay b7ce7bfe18 Arduino 1.0 - small fix to make AP_Baro_MS5611_test.pde compile under Arduino 1.0 2012-01-28 13:21:35 +09:00
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).

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
