Peripheral ADC[edit | edit source]
Description[edit | edit source]
The ADC interface available on ETRA SoM is based on STM32MP1 SoC.
The ADC port supports the following standards and features:
- up to 2x ADCs which can operate in dual mode
- 16, 14, 12, 10 or 8-bit configurable resolution
- ADC conversion time is independent from the AHB bus clock frequency
- can manage Single-ended or differential inputs
- self-calibration (both offset and linearity)
- up to 6 fast channels
- up to 14 slow channels
- speed adaptive low-power mode to reduce ADC consumption when operating at low frequency
- 3 analog watchdogs per ADC
- ADC input range from DGND to VDD
Pin mapping[edit | edit source]
Each CPU port can be configured as analog input.
The Pin mapping is described in the Pinout table section
