MCU-PLUS-SDK-AM263X: How to use ADC_CAL0 and ADC_CAL1

Hello everyone,

I wonder how you can use ADC_CAL0 and ADC_CAL1 in software. There is no example or anything apart a description in the AM263x academy. How can these ADC be triggered? I can't see something in the sysconfig tool either. Can we use these ADC inputs as normal ADC inputs not reserved for calibration?

Hi Loic,

Greetings. These CAL pins can be selected as part of the ADC_setupSOC() API. using the below enumeration. we may use these pins for normal ADC inputs, but ideally, it may not be the use case as these 2 pins are common for all the ADC's in the SOC. Essentially, ADC_CAL0, ADC_CAL1 are shorted to channels 7,8 across all the ADC's.
