6.8.2 Quick Start Guide for DAC - Callback

In this use case, the DAC will convert 16 samples using interrupt driven conversion. When all samples have been sampled, a callback will be called that signals the main application that conversion is compete.

The DAC will be set up as follows:

  • Analog VCC as reference

  • Internal output disabled

  • Drive the DAC output to the VOUT pin

  • Right adjust data

  • The output buffer is disabled when the chip enters STANDBY sleep mode

  • DAC conversion is started with RTC overflow event
