Hello to and thanks so much to whoever is reading this:
Arduino board: Nano 328
After I uploaded the builtin example File->Examples-> Digital -> DigitalInputPullup , my nano board's TX led is stuck ON, and each time I try to reprogram it via USB, it crashes my Mac computer.
I also tried using another nano board as ArduinoISP to overwrite the troubled program, but programming also fails.
I have 2 questions:
- Is there something wrong with the builtin DigitalInputPullup sketch?
- How can I erase the bad programming on my nano boards?
Any help would be appreciated.
