Andrew Tridgell cc4bae4b42 fixed inconsistent linefeeds in ADC code
the linefeeds had bacome inconsistent in this library, making some
editors fail to load the code

Andrew Tridgell a828d00125 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

Andrew Tridgell 2ae78e197e 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 1c5e8f0381 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 8a31af801f 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 65345160d1 Implemented moving average filter to deal with noise issues on quads, default is a 6 member filter.
