I have an arduino pro and an arduino uno. In my application the arduino uno works but the arduino pro doesn’t. I am using an sd logging breakout board and it won’t initialize on the pro when it will on the uno.
On the pro, I can readDigital correct on the pins, digital 10, 11, 12, and 13. And I can writeDigital to them and they seem to work. Are there any other tests I can do to see if something else is wrong with the pro?
I just double checked my work and I can’t read or write to pin 11. The device I’m using is an SPI device. I sssume there is no work around for this.
