I have a max32 and I'm having problems with one of the digital ports. It seems that when i set HIGH on the digital port of number 51, only 0.95 volts are coming out instead of the 3.3V. Is there any possible solution?

Tanks in advance.

Are you sure you've switched the port to output with a pinMode() first?

Yes, I did it already

Are you using SPI?

It could be that the system is toggling the HIGH/LOW so fast it looks like 1V.
