Peripheral DAC[edit | edit source]
Description[edit | edit source]
The DAC interface available on ETRA SoM is based on STM32MP1 SoC.
The DAC port supports the following standards and features:
- one DAC interface, maximum two output channels
- synchronized update capability
- noise-wave and Triangular-wave generation
- dual DAC channel for independent or simultaneous conversions
- DMA capability for each channel
- external triggers for conversion
- DAC output channel buffered/unbuffered modes
Pin mapping[edit | edit source]
DAC I/O connections:
- DAC1_OUT1 on PA4
- DAC1_OUT2 on PA5
The Pin mapping is described in the Pinout table section
