Andrew Tridgell	c8befe4536	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	13 years ago
Andrew Tridgell	10e546eebd	AnalogSource: return a float from read() method this gives the full resolution when using the ADC backend. It also adds scaling for the Arduino backend	13 years ago
Randy Mackay	1f53c25577	RangeFinder - small bug fix to initialise prescale variable. Fixed up example sketch so it compiles and works again!	13 years ago
Pat Hickey	0c0a1b1dcc	purple: Added AnalogSource library this library abstracts out the way of getting an analog value. If the ADC library is being used then it calls the ADC Ch() method, otherwise it calls analogRead()	13 years ago
