Atmel AT91M55800A D/A Example Program

This example program shows how to configure and use the D/A Converter of the following microcontroller:

  • Atmel AT91M55800A

The program configures the D/A and generates a sine wave on the DAC0 channel and a sawtooth waveform on the DAC1 channel.

To watch the effect this program has on the D/A Converter:

  1. Build the program (Project-Build Target).
  2. Start the Debugger (Debug-Start/Stop Debug Session).
  3. Open the D/A Converter Dialog Box (Peripherals D/A Converter).
  4. Make sure View-Periodic Window Update is checked.
  5. Run the program and watch the D/A outputs change.

When the program writes to DAC0 you will see the corresponding registers change in the D/A Converter dialog.

µVision3 users may enable the built-in Logic Analyzer to view and measure the digital input and analog output signals graphically.
