rmackay9 1c7118a2d1 AP_Baro: added get_last_update which returns the time the barometer sensor was last read 2012-11-07 19:21:25 +09:00
Andrew Tridgell e5846bd965 AP_Baro: removed _sync_access check 
this isn't needed as the common variables are already protected by
cli()/sei()

Andrew Tridgell c9ba693e1f AP_Baro: the HIL baro needs to inherit calibrate() from the parent class 
this was what caused the renorm errors
 2012-08-18 16:32:23 +10:00
Andrew Tridgell 034fb5b194 APM: fixed hil build 2012-08-16 12:53:37 +10:00
Andrew Tridgell 518d6365ff AP_Param: update remaining libraries for new constructor syntax 2012-08-08 12:11:57 +10:00
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.

Andrew Tridgell 3c7e521f70 AP_Baro: update MS5611 test to use baro library altitude 2012-07-06 15:11:30 +10:00
Andrew Tridgell 209136386b AP_Baro: added get_pressure_samples() interface 
this returns how many samples were used to calculate the last pressure
 2012-07-05 16:29:21 +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 9f8703274c AP_Baro: show climb rate in baro test sketch 2012-07-05 13:00:45 +10:00
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

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.

Jason Short 026e4a6567 change constant to float 44330.0 2012-02-15 09:10:14 -08:00
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

Andrew Tridgell e7720254dd AP_Baro: update MS5611 driver for new ap_proceduce prototype

Andrew Tridgell bb0f179495 AP_Baro: fixed temperature on MS5611
