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.

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

6710cf5c5a Wire and SPI Init: move to sketch system.pde from libraries 
* Wire.begin removed from AP_Baro_BMP085::init()
* SPI.begin  removed from AP_Baro_MS5611::init()
* SPI.begin  removed from AP_InertialSensor_MPU6000::hardware_init()

* Both Wire.begin and SPI.begin added very early in init_ardupilot in
  ArduCopter/system.pde and ArduPlane/system.pde
