I have been playing with the 5v serial LCD as part of a development I am doing with the arduino Duemilanove board. I used the example code from http://www.arduino.cc/playground/Learni … kFunSerLCD Everything was working just fine at the beginning but now I am getting nothing but random characters across the screen and can’t seem to revert back to my code which worked. I suspect that Leaving the lcd connected during downloading of new code sent a command to the Serial board and changed a setting. Is there an easy way to revert the serial board back to its factory settings? Or is there anything else you could possibly think is the problem.
Thanks,
Greg
