Hi SithRouss,

It should be IOPORT_E rather than IOPORT_F as you found. I'm guessing that whoever created the header file misread the schematic for that particular pin since it (at first glance) does look like it should be on Port F rather than Port E (at least on the schematic).

There are two things that I can think of that you should try, having worked with the PmodOLED quite a bit. The first would be to make sure that you are applying 3.3V of power to the Pmod rather than 5V. The second would be to actually tie pin 1 of the PmodOLED to Ground (0V) to ensure that the module on the PmodOLED stays enabled.

Let me know if you have any more questions.

Thanks,
JColvin
