PGA2310 Volume Control device
Provides a simple analog device that can be used to control a PGA2310 volume device. Left channel is 0 and right channel is 1. The device should be connected on the SPI bus as usual. This should work with Arduino now, and mbed in a patch release coming soon. To use first include the header:
#include <extras/Pga2310VolumeControl.h>
Then initialise globally:
SPIWithSettings spiSettings(&SPI, CS_PIN);
Pga2310VolumeControl pga2310(spiSettings);
And to use it as a floating point value
pga2310.setCurrentFloat(volFlt); // where the value is between 0F and 1F
float f = pga2310.getCurrentFloat(); // where the value is between 0F and 1F
or as an integer
pga2310.setCurrentValue(intVal); // where the value is between 0 and 255
unsigned int val = pga2310.getCurrentValue(); // where the value is between 0 and 255
This covers everything for this device.
