There is no embedded ADC peripheral implemented at DPA. The reason is that there are many diverse requirements (number of channels, channel selection, conversion time, conversion precision, etc.) to the actual ADC peripheral implementation.
This example implements analog to digital conversion from two channels. Intentionally these channels can be driven directly by a photoresistor and a potentiometer and available at DDC-SE-01.
→ Self-study tip: Implement user two-byte FRC command that will return MSB values from both ADC channels at once.
