Hi, I am trying to upload a sketch to my MEGA, but when I plug the board into the computer, it won't show up under the serial port menu. I have tried multiple reinstalls of the IDE, and 9 different computers. Mac Linux Windows7, 10. Is my board toast? My other boards work fine.
If nothing, is it possible to program it with an FTDI cable somehow?
Thanks for any help, –diodes123
