This is a small and simple library to control the DAC7611 digital to analog converter (DACs) with an Arduino board.

The DAC7611 is a 12-bit digital-to-analog converter with guaranteed 12-bit monotonicity performance over the industrial temperature range. It requires a single +5V supply and contains an input shift register, latch, 2.435V reference, DAC, and high speed rail-to-rail output amplifier.

To operate the DAC, first create an instance of the DAC using DAC7611 dac(cs, ld, clr) next initialise the dac using dac.begin() and send data with dac.analogWrite(int value)

#include <DAC7611.h>

uint8_t cs = 8;
uint8_t ld = 2;
uint8_t clr = 3;

DAC7611 dac(cs, ld, clr);

int dacVal = 0;

void setup()
{
  Serial.begin(9600);
  dac.begin();  //initialise DAC
  Serial.println("Hello");  
}

void loop()
{
  if (Serial.available() > 0)
  {
    dacVal = Serial.parseInt();
    dac.analogWrite(dacVal);  //send values to DAC
    Serial.print("DAC Value is : ");  
    Serial.println(dacVal);
  }
  delay(1000);
}

This library depends on the standard SPI library.
