I'm using the evaluation kit for QN9080 and I want to use one channel for the ADC. I used the config tools for pin configuration in MCUxpress IDE and selected channel 4 which is routed to GPIOA8/PA08 . However when I give an analog signal on PA08 of the evaluation kit, I don't see any changes.
I did refer to the developer manual which only says that GPIOA8 is routed to PA08
Can someone help me what else needs to be done in order to make it work?
