I have built a giant setup of my flight simulator and each time I connect a new Mega 2560 card it seems to collide with an already present Mega 2560 card connected to the flight simulator.
For an instance, when I made my MCP I programmed the arduino on a stand alone computer. Then when it was completed I disconnected it and installed it into my flight simulatorm, just to find out that I had to reprogram all Mega 2560 cards since it has been some interference between all my mega cards connected to the sim before the MCP.
So my question is, is it possible to give an Arduino Mega 2560 a unique serial number and name so this will not happen when I connect a new device again?
There should be a solution for this problem, or is it impossible?
