Andrew Tridgell 175b6d2606 AP_AnalogSource: fixed reporting of VCC
the VCC pin number should not be converted
2012-07-21 19:49:24 +10:00
rmackay9 4dd4c95d5c 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

Andrew Tridgell d755fedc26 AnalogSource: prevent a division by zero on zero ADC data 2012-07-06 19:59:18 +10:00
Andrew Tridgell 769011e947 AnalogSource: added some example code 2012-07-01 15:01:05 +10:00
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

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).

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

Randy Mackay 1f53c25577 RangeFinder - small bug fix to initialise prescale variable.
Fixed up example sketch so it compiles and works again!

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()
