I've been using the Mega2560 up until today. I've been attempting to setup an old Mega1280. I'm using a code that I know works perfectly on my 2560 but I can't even get it to connect to this board. It's giving me and error that it cannot find the com.
avrdude: ser_open(): can't open device "\.\COM7": The system cannot find the file specified.
I've looked through my device manager and it won't display any ports other than my 2560.
It's currently under Board: Arduino/Genuino Mega or Mega 2560
and Processor: ATmega1280
Any ideas why I can't get it to connect and how to fix it? I've been searching for hours.
