Hi,

I have a sensor connected at analog pin AN3 of TC389QP-160 Evaluation board whose values are being read using EVADC Group0 Channel 3 and result register at EVADC_G0RESD2.

I am not able to monitor the converted values from Sensor in Trace32 watch window. On checking at EVADC result register, it is always zero.  The observation is same for other configured analog pins through EB-tresos . However, DIO pins are working properly for both of the input/output configurations.

I am not sure about whether that is a hardware pin issue or EVADC is not working. I would first like to analyze if there is an issue with EVADC on the hardware board.

There seems to be no issue with the software as same software is working fine on other TC389QP-160 board and the sensor values from EVADC can be monitored properly.

Please suggest some ways to debug the EVADC issue.

Hello,

Can you check if the ADC power supply voltages are correct? If so, perform the diagnostics test present in the EVADC hardware and check the behavior?

Thanks.
