A simple Arduino Library for the Analog Devices AD7390 digital-to-analog converter (DAC).

To use the library include the header-file and initialize an object as follows:

#include <AD7390.h>

#define DAC_CS 8
AD7390 dac(DAC_CS);

To send a new value to the DAC call the following function:

uint16_t value = 1024;
dac.writeValue(value);

That's it. There are also some examples available for better understanding.
