Andrew Tridgell e491168273 ADC: remove a very small (0.2 degrees/s) bias in the ADC code
small bias from integer rounding

Pat Hickey 017f121566 AP_ADC: rework ADC library to use PeriodicProcess and ISR_Register
this makes it possible to build the ADC library when another driver
may also want that interrupt

Jason Short 0bfa67f413 Heavy Accel Filter + mild Gyro Filter. To use, filter_result must be set to true on ADC. Off by default. 2011-10-01 15:44:53 -07:00
Jason Short f89da12387 Minimized the accel_filtered vector to be faster and more accurate.
Made the Filter include the Accels and moved from 8 to 4 terms in the filter

Jason Short de61e87128 Added ADC gyro Filtering for quads - this fixes a noise issue introduced into the controller
added Position mode
removed
Added back in the accelerometer experiment
Added filter_result boolean to enable filter on the fly

Andrew Tridgell f375258699 fixed inconsistent linefeeds in ADC code
the linefeeds had bacome inconsistent in this library, making some
editors fail to load the code

Andrew Tridgell a835912d93 ADC: randomise the sampling rate
this is based on suggestions from Kari and Mike, and should reduce the
aliasing effects we get from the simple averaging
2011-09-17 14:58:02 +10:00
Andrew Tridgell 1d68953416 ADC: the bottom 3 bits of ADC output are always zero
its a 12 bit ADC .... silly of me to think the bottom 3 bits are
valid!

Andrew Tridgell 9af7021a98 change ADC sample rate to 1kHz
this costs us about 9% of our CPU, but should make aliasing much less
of a problem.

Andrew Tridgell 70bf945d40 ADC: re-work for ADC code for full resolution and accurate timing
this changes the ADC code to return the full resolution of the
sensors. It also adds a new Ch6() interface that returns 6 channels at
once, so the IMU can read 3 accelerometers and 3 gyros at once, and
get the exact time that the values were accumulated over

jasonshort c1ddd58d4c Implemented moving average filter to deal with noise issues on quads, default is a 6 member filter.
