NB2AS DAC Example

The NB2AS has a TLV5618 dual 12-bit DAC with a 1.24V reference. The DAC library contains the functions to initialize the DAC object, set the output voltage. The example program initializes the DAC and sets channel A to 0.75V, B to 0.5V.

When initializing the DAC object you need to define which pin number is connected to the CS pin. The example code below creates a DAC object using the default pin assignment for the NB2AS.


// the load pin is attached to pin 10 (PB2)
// and the latch pin is attached to pin 9 (PB1)
// the spi port is attached to spi0

#define DAC_CS_PIN  4 // Sanguino Pin Number (ATmega644P PB4)

LED_debug led;

DAC_TLV5618 dac  = DAC_TLV5618(DAC_CS_PIN);
