I have successfully tested "lpc_adc_basic" sdk example for reading adc values on lpcXpresso54608 development board and its working.
I downloaded the sdk for LPC54616J512 and then started a new project for reading adc values using custom made LPC54616 board, but the output values is always 4095(high) (even when I try to read say 0 volts).
I have properly configured port and pins of ADC channel 3,4,5 and etc. I don't know if any clock configuration is needed.
PFA below of the zip containing the project for basic adc example.
It will very helpful if someone in the community is able to point me in the right direction.
Thanks & Regards,
