cli()/sei()

Andrew Tridgell 7d8903a8bf AP_Baro: the HIL baro needs to inherit calibrate() from the parent class
this was what caused the renorm errors

Andrew Tridgell b0e403e6fb AP_Baro: the DerivativeFilter now handles duplicate data
this saves a few bytes of memory

Andrew Tridgell 44755bf3ce 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 735c88e9b3 AP_Baro: added get_pressure_samples() interface

Andrew Tridgell cf2c546051 AP_Baro: show climb rate in baro test sketch 2012-07-05 13:00:45 +10:00
Andrew Tridgell 7a77832f45 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 f7b06e0a64 Baro: fixed build of MS5611 test code 2012-07-02 13:44:53 +10:00
Andrew Tridgell 57579e494b 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 53e950531e 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 bad6591e6d AP_Baro: fixed comment to clarify that every-other call updates temperature or pressure 2012-06-03 17:31:17 +09:00
Andrew Tridgell ae1702c20b Baro: added suspend/resume on init 2012-05-01 12:06:54 +10:00
rmackay9 dc58c8a905 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 f3eb15167c 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 ed0d1da4f5 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 13e9608fb8 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 34cf1e8fb3 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 0311b70004 AP_Baro - fixed small compiler warning to do with order of parameters in constructor 2012-02-29 22:46:29 +09:00
justinbeech 5255512bf9 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 e70e1814ac AP_Baro: fixed some signed/unsigned warnings
and a potential bug on timer wrap
2012-02-13 21:39:18 +11:00
justinbeech 4b0c71d6ac 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 2e1e34fb9c 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 98f3386ea0 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 817e7442bd 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
