s32k116-evb ADC

I'm am working on s32k116-evb for ADC data receiving and for that I'm using "adc_swtrigger_s32k116" example code. but when i use ADC0 channel, PTA0 that time only I'm getting o/p other pin and port not giving o/p(like PTA7,PTB2). already check on board side connection,port and pins etc. everything is ok. give me suggestion.

Please confirm whether you are testing the S32K116EVB2Q048 or S32K116EVB-Q048 . Resistors connected to many pins show that DNP (Do Not Populate) is actually not soldered.

That example select ADC_INPUTCHAN_EXT0(PTA0) by default, did you change it to ADC_INPUTCHAN_EXT3(PTA7) or ADC_INPUTCHAN_EXT6(PTB2)?

Best Regards,
Robin

I'm testing on S32K116EVB2Q048 board. and yes I'm change it to ADC_INPUTCHAN_EXT3(PTA7).

But R750 is DNP, which means: ADC_POT is not connected to PTA7 on S32K116EVB2Q048.

then which PIN and PORT i can use for ADC testing

If you want to sample the voltage of ADC_POT, then you can connect PTA7 or PTA0 to TP528, or short R750 (PTA7 ADC0_SE3) or R670 (PTA0 ADC0_SE0) by soldering.
