iMXRT: ADC_ETC Configuration Problem

Sam_ECU — Wed, 03 Jul 2024 12:22:26 GMT

Hello,1

I'm working with iMXRT1062 and can't get ADC2_IN1 (Pin H12) to correctly read a voltage input using ADC_ETC in MBDT.

In total I'm measuring 12 pins and I only have issues with ADC2_IN1, the other pins measure fine. I'm also measuring most of the pins in ADC1 and a higher sample rate.

The setup is based off the example "ADC_ETC_Hardware":

I can measure on the pin with a multimeter and there is no issue in the hardware. I can also take the "ADC_Polling" example and measure on ADC2_IN1 without issue. I know the issue is in the software and not in the hardware.

What is the issue in my setup using ADC_ETC?

Attached my config files based off "ADC_ETC_Hardware" and "ADC_Polling"
