DAC Output component
CAL = Code Abstraction Layer - Allows one code base to run on a wide range of chips. A low level implementation giving direct access to the Digital to Analogue Converter peripheral.
Examples
Example to configure the DAC output and ramp up the output voltage to create a sawtooth waveform.
If the Scope traces property is set to Yes then the DAC voltage will be shown on the Data Recorder window.
Example to configure the DAC output and control the output voltage to create a sine waveform.
