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.
