D/A Converter Simulation

The µVision Debugger simulates the on-chip D/A Converter of most devices. All registers are fully simulated and the analog outputs may be viewed and changed in real-time.

The Digital/Analog Converter dialog box displays and allows you to adjust special function registers associated with the D/A Converter.

You may create debugger scripts that monitor the D/A output voltages. For example, the following script:

signal void dac_monitor (void) {
while (1) {
  wwatch(DAC0);

  if (DAC0 > 2.0)
    printf("D/A output is high (%f Volts)\n", DAC0);
  }
}

watches writes to the DAC0 VTREG and outputs a message if the output voltage exceeds 2.0 volts.
