I was willing to buy a metro 328 board but they are out of stock except for the $45.00 one.
The mega board will list what seems to be correct data on the serial display but nothing is shown on the OLED.
In my original post when I said “ change the board “, I was referring to within-the-code, selecting the board that is in use. Not changing the physical board.
Does that make sense ?
I need to find an easier OLED example.
Thanks
