Andrew Tridgell fc63087cb8 AnalogSource: switch to SREG = oldSREG pattern for interrupt mask/restore 2012-11-20 22:31:09 +11:00
Andrew Tridgell 403721f8ca AP_AnalogSource: allow for the 'NONE' pin in Arduino ADC
This allows us to have a configuration parameter for a pin which
defaults to -1, meaning not to read a pin at all. It will always
return 0

Andrew Tridgell a979fb6014 AP_AnalogSource: added set_pin() interface
this allows pin numbers to be changed at runtime

Andrew Tridgell a4b1b9f0a4 AP_AnalogSource: make read_average() return a float
this allows it to take advantage of better than 1 bit resolution by
averaging

Andrew Tridgell 175b6d2606 AP_AnalogSource: fixed reporting of VCC
the VCC pin number should not be converted

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 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

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()
