Hi Tom, I just received an Arduino Mega2560 from China. Tested with some Arduino example scripts (EEPROM read and write also) and seem to work fine. I connected the board to an USB port of my laptop and I uploaded the firmware, then loaded an existing configuration (EQ3-2 type1), just to try. All goes well but when AstroEQ launch EQMOD to test the mount EQMOD give me an error about Connection error (mount not found, see attached figure). Currently I have the Mega2560 board alone, connected to laptop. No other hardware.
Thanks,
Gigi
