Hi,

i have assinged the mux_output0 pin for ADC1. the channel number is not mentioned, which channel use to read the value.

i saw in the configuration ANAMUX_OUTPUT channel. is this correct?

Attached the screenshort.FYR.

Hi@vasanth-sr

No, for example,you can check the specific channel number like the way below.

the PTC27->ADC1_MA[0]

Hi team,

In our design, pin no 93 -ADC1_MA[0] (ADC1 -> mux_output0 -> PTC27) used to read voltage.

I configured this pin, this pin default direction is output not configurable as a input.

How can i configure and read ADC value from this ADC1_MA[0]?
