\section{DAC Unit}
|
|
|
|
The digital/analog unit works with the two-channel DAC peripheral of the microcontroller. It can be used in two modes: DC output, and waveform generation.
|
|
|
|
The waveform mode implements direct digital synthesis (explained in section \ref{sec:theory-dac-dds}) of a sine, rectangle, sawtooth or triangle wave. The generated frequency can be set with a sub-hertz precision up to the lower tens of kHz. The two outputs can use a different waveform shape, be synchronized, and their phase offset, as well as frequency, is dynamically adjustable.
