rmackay9	1105a35c77	AP_AnalogSource_Arduino: fix to allow analog port to be read to be specified as a "channel" (i.e. A0) ... Also fixed example range finder sketch to work with interrupt enabled AP_AnalogSource_Arduino class	2012-07-11 21:19:17 +09:00
Andrew Tridgell	ec70e87495	AnalogSource: prevent a division by zero on zero ADC data	2012-07-06 19:59:18 +10:00
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
Randy Mackay	98f3386ea0	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).	2012-01-28 12:25:47 +09:00
Andrew Tridgell	7c939e83e0	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	2011-12-17 07:29:09 +11:00
Pat Hickey	0caf351c32	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()	2011-11-25 20:00:16 -08:00
