Peripheral ADC[edit | edit source]
The ADC module available on AURA is based on i.MX93 SoC. The SOC has one instance of the ADC module: it is an 8-channel 12-bit 1MS/s ADC with 4 channels connected to pins in the package. It has its own dedicated pads and is not muxed with GPIO.
Description[edit | edit source]
The ADC port supports the following features:
- Successive Approximation Register (SAR) method
- 4-channel, 12-bit resolution
- Multiple modes of starting conversion (Normal, Injected)
- Software-initiated conversions in Normal and Injected modes, or external hardware trigger
- Programmable DMA enables for each channel
- Programmable presampling for channels
- Programmable clock prescaler
- Software-initiated calibration
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
