Hi. I made MIDI IN and it worked. But now it is not working. I suspect I broke RX pin, is there a way to check it?
story: it worked ok, then I diassaembled my project, did not touch it for a while. Yesterday I need midi in and out again. I messed RX with TX pin, and one time MIDI OUT cable from synth was connected to RX pin, I unplugged arduino from USB, but it was still working ^^ Then I realised that it powered from MIDI OUT jack from synth that was connected to V, GND and RX pin. Is there a chance that I broke RX pin?
Arduino R3, loopback test passing.
UPD: All fine, something wrong with my breadboard.
