Hi,

 

Can Vref pin (10) on CYBLE-212019 be set up as digital input? I have a switch connected to it.

How?

Thanks

Fidel

Vref cannot be used as input. A trick could be to switch Vref between two voltage levels and have the ADC convert a fixed analog voltage to see whether Vref changed.

Did you already free the two pins that are used for debugging?
