Andrew Tridgell	2046e396a2	AnalogSource: make the Arduino AnalogSource interrupt driven this fixes several problems with reading analog sources: - we were getting poor values because we didn't wait long enough for an analog source to settle - we wasted a lot of CPU cycles waiting for conversions - we were not taking averages over many samples, which we did with the old AP_ADC driver on the APM1	2012-07-01 15:01:05 +10:00
Andrew Tridgell	57ac39649a	TimerProcess: added suspend_timer()/resume_timer() this will be used to avoid races in driver initialisation	2012-05-01 12:06:54 +10:00
Andrew Tridgell	0a08a0b515	TimerProcess: make some variables uint8_t save a couple of bytes	2011-12-28 16:00:48 +11:00
Andrew Tridgell	8cc2b7669b	PeriodicProcess: added set_failsafe() call this adds an optional failsafe function that will be called in the timer loop	2011-12-21 23:31:38 +11:00
Andrew Tridgell	5b4717ea55	timers: change to 1kHz timer by default we were using a 227Hz timer, which is far too slow	2011-12-16 20:09:25 +11:00
Pat Hickey	a7b9c8b9cd	AP_PeriodicProcess: AP_TimerProcess can register multiple callbacks.	2011-12-11 15:21:10 -08:00
Pat Hickey	7474a8be53	purple: added PeriodicProcess library this library provides a clean API for drivers to request periodic timer driven calls at whatever rate they need	2011-11-25 20:00:16 -08:00
