6.8.1.2.2 Workflow

  1. Create a temporary variable to track the current DAC output value. 
    uint16_t i = 0;
  2. Enter an infinite loop to continuously output new conversion values to the DAC. 
    while (1) {
  3. Write the next conversion value to the DAC, so that it will be output on the device's DAC analog output pin. 
    dac_chan_write(&dac_instance, DAC_CHANNEL_0, i);
  4. Increment and wrap the DAC output conversion value, so that a ramp pattern will be generated. 
    if (++i == 0x3FF) {
    i = 0;
}
