Andrew Tridgell 47da2ec992 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

Andrew Tridgell ff727e87ca ADC: remove a very small (0.2 degrees/s) bias in the ADC code
small bias from integer rounding

Pat Hickey 6d876bc54d 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 945a7c13a7 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 cf59e8ad82 Merge branch 'master' of https://code.google.com/p/ardupilot-mega 2011-09-30 18:40:40 -07:00
Jason Short 9a4bd31a8b 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

James Goppert ac3e73f5c0 Optional recursion added. 2011-09-30 17:17:51 -04:00

Jason Short df1a39f650 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

James Goppert 3a00ceb593 Added ArduBoat/ ArduRover/ and APO library. 2011-09-29 14:12:15 -04:00
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 1b5c7e8a90 ADC: show timing information in ADC test 2011-09-17 14:58:02 +10:00
Andrew Tridgell 4a7c9c406f show noise levels in ADC test 2011-09-17 14:58:02 +10:00
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!
2011-09-17 14:58:02 +10:00
Andrew Tridgell 812cd3562f updated ADC test for new API 2011-09-17 14:58:02 +10:00
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

unknown 9f028bb5a0 Adding CMake support 2011-09-14 15:44:55 +02:00
Jason Short 4a2f58b013 Cleaned up guided mode
Reduced ADC filter to 3 from 6 to increase speed of filter.

jasonshort 5c3837757a Added ability to grab an unfiltered value from the ADC
