Tutorial - Serial LCD quickstart about 3 years ago

I hooked up the LCD display to an Arduino 2560. Every time I reprogrammed the 2560 through the USB the LCD would print garbage. Finally, after a couple of time I reprogrammed the 2560, the LCD would dim. To get it back to the right light level, I had to write the command to bring the light level up. Otherwise, it would stay at that level even after recycling power.

After reprogramming the 2560 a few more times, My character map changed. It looked like it went to a 20 character display or something. I tried resetting it back to the 16x2 by sending the 124 command then sending a 4. But that didn’t work. Does anyone out there know how to reset this device back to its normal parameters?

No public wish lists :(
