ADC: removed the ADC level accel smoothing
...
the quaternion code does a better job of handling this noise than this
filter does

ADC: use floats for ADC averaging
...
this costs almost nothing and improved accel/gyro calibration

AP_ADC: added new_data_available() interface
...
returns true if more samples are available

Revert "ADC: added an enable_channel() API"
...
This reverts commit dafeac01d8f14162600cf821404ba4072dcae14d.
ADC will be disabled on APM2

ADC: added an enable_channel() API
...
enable_channel() must be used before the Ch6() method is called to
enable gathering of data on the required channels

fixed formatting of ADC driver
...
it was a nasty mix of DOS and UNIX

ADC: change adc.Ch() to return a float
...
this gives us a bit more precision in airspeed measurement, and costs
us virtually nothing as we are converting to float immediately after
getting the value

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

Heavy Accel Filter + mild Gyro Filter. To use, filter_result must be set to true on ADC. Off by default.

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

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

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

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

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
2011-09-17 14:58:02 +10:00

Cleaned up guided mode
...
Reduced ADC filter to 3 from 6 to increase speed of filter.

Added ability to grab an unfiltered value from the ADC
