Andrew Tridgell	f9394f8068	ADC: removed the ADC level accel smoothing the quaternion code does a better job of handling this noise than this filter does	13 years ago
Andrew Tridgell	a0a360f955	ADC: use floats for ADC averaging this costs almost nothing and improved accel/gyro calibration	13 years ago
Andrew Tridgell	c80ec9a55c	AP_ADC: added new_data_available() interface returns true if more samples are available	13 years ago
rmackay9	c444cdb3f4	AP_ADC - removed small compiler warning	13 years ago
Andrew Tridgell	79d622939a	ADC: on channel overflow we should not zero last_ch6_micros this happens every 64 seconds because of unused channels on the ADC. Zeroing this creates a bad delta_t value for the DCM code.	13 years ago
Randy Mackay	cf25bbfa74	AP_ADC library - tiny fix to make example sketch work after some changes to AP_PeriodicProcess library	13 years ago
Randy Mackay	ed19c25a97	Arduino 1.0 - changed all #includes of "WProgram.h", "wiring.h" and "WConstants.h to "Arduino.h". Modified FastSerial's write function to return size_t (number of bytes written).	13 years ago
Jason Short	94e7ba8df2	Removed Gyro filter, In the end it doesn't help and I think it could actually hurt gyro integration.	13 years ago
Jason Short	354d9588bf	sensorSign swicth	13 years ago
Andrew Tridgell	8780a60234	ADC: update for new ap_proceduce prototype	13 years ago
Andrew Tridgell	6341db7031	Revert "ADC: only read channels that are actually being used" This reverts commit 95e6bb26f4772ca8c7faa62215de6f078d3df3c7. ADC will be disabled on APM2	13 years ago
Andrew Tridgell	d442bad413	Revert "ADC: added an enable_channel() API" This reverts commit dafeac01d8f14162600cf821404ba4072dcae14d. ADC will be disabled on APM2	13 years ago
Andrew Tridgell	99eafbbe38	Revert "ADC: fixed HIL build" This reverts commit 86c1a6a5fdd929516cf0f64f4d610cfcd4b4f774. ADC will now be disabled on APM2	13 years ago
Andrew Tridgell	f6f808357c	removed AperiodicProcess code this code was never being used, and was more complex than it was worth.	13 years ago
Andrew Tridgell	d4b66139dc	ADC: fixed HIL build	13 years ago
Andrew Tridgell	9591317dbc	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	13 years ago
Andrew Tridgell	09947dace1	ADC: only read channels that are actually being used on the APM2 we usually use none of the ADC channels, although we may use the airspeed sensor. This change means we detect which channels are being read, and only do the SPI transfers for those ones. That saves us about 100usec per timer interrupt (ie. about 10% of our CPU)	13 years ago
Andrew Tridgell	f125f6619a	fixed formatting of ADC driver it was a nasty mix of DOS and UNIX	13 years ago
Andrew Tridgell	5d503fd65e	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	13 years ago
Andrew Tridgell	e491168273	ADC: remove a very small (0.2 degrees/s) bias in the ADC code small bias from integer rounding	13 years ago
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	13 years ago
Jason Short	0bfa67f413	Heavy Accel Filter + mild Gyro Filter. To use, filter_result must be set to true on ADC. Off by default.	14 years ago
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	14 years ago
James Goppert	0c7c508541	Optional recursion added.	14 years ago
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	14 years ago
James Goppert	5489b84f8e	Improvements to cmake.	14 years ago
James Goppert	d887a28b91	Added ArduBoat/ ArduRover/ and APO library.	14 years ago
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	14 years ago
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	14 years ago
Andrew Tridgell	840c256fe3	ADC: show timing information in ADC test	14 years ago
Andrew Tridgell	197b1d140a	show noise levels in ADC test	14 years ago
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!	14 years ago
Andrew Tridgell	bd30840518	updated ADC test for new API	14 years ago
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.	14 years ago
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	14 years ago
unknown	a4e001bbcf	Adding CMake support	14 years ago
Jason Short	ecd14f4425	Cleaned up guided mode Reduced ADC filter to 3 from 6 to increase speed of filter.	14 years ago
