New to Arduino and I have a UNO and DUE.
On the DUE, I tried to get a serial port mirror working - where I copy incoming data on 1 port and write it out on the other port and same in reverse. This isn't working - garbage and shifted bits/bytes seem to be being transmitted instead - I'm actually getting really weird results.
Quick question to avoid me working on this further when clearly it won't work, do I need to consider that Serial1 through Serial3 on the DUE are at 3.3v TTL and therefore I can't just wire them directly to most serial ports working at 5v ?? If so, what was the point of 3.3v TTL ports? Do any cheap converters exist that I can wire in???
Perhaps I should have bought a Mega then??
