Support Arduino Uno R4 minima

[itslemcy]

Hi, i tried my old code for the arduino uno R3 on my new R4 but i get random outputs such as:

18:28:09.506 -> Max!
18:28:10.492 -> Max!
18:28:16.494 -> Push: 
18:28:17.481 -> Increment: 255
18:28:20.494 -> Increment: -256
18:28:23.481 -> Max!
18:28:24.496 -> Max!
18:28:30.507 -> Push: 
18:28:31.494 -> Increment: 255
18:28:34.485 -> Increment: -256
18:28:37.508 -> Max!
18:28:38.480 -> Max!

They are mechanically connected in the same way, any ideas? Thanks"

Hello, I don't have such board so i can't test. But that error is because the I2C is not working, and it read all 0xFF Plus the INT pin is always LOW Maybe there is no pull-up resistors mounted.
