.. _dac-sample: Digital-to-Analog Converter (DAC) ################################# Overview ******** This sample demonstrates how to use the DAC driver API. Building and Running ******************** The DAC output is defined in the board's devicetree and pinmux file. Only board nucleo_l073rz is supported for now. Sample output ============= You should see a sawtooth signal with an amplitude of the DAC reference voltage and a period of approx. 4 seconds at the DAC output pin specified by the board. The following output is printed: .. code-block:: console DAC internal reference voltage: 3300 mV Generating sawtooth signal at DAC channel 1. .. note:: If the DAC is not supported, the output will be an error message.
