I Bought this screen (http://www.4dsystems.com.au/prod.php?id=114) several months ago, I found this tutorial (http://www.mauroalfieri.it/informatica/tutorial-ulcd-32pt- e-arduino-come-programmatore-seriale.html) to use it, I tested this in Arduino UNO like the tutorial explains. Everything worked fine but when I tested with Arduino Mega 2560 use pins 2 - 3 - 4 because I had not read that to apply the library I found (https://github.com/rei-vilo/Serial_LCD) in the tutorial should use pins 10 11 12 13 50 51 52 53 for Arduino Mega.
Now when I load the sample program I had used before and worked in the Arduino UNO does not work on the screen but I told myself that the platform is loaded. Not happening, could it be that the screen is damaged? (Something weird because I can still change the mode (SGC | GXF) with PMMC loader) or Could it be because I’m using version 1.5.2-arduino? but because it worked before, so I guess that does not matter because the libraries are compatible with arduino 1.0 and 1.5.2 or no?
How to know that my screen is broken??? :~
I need help because I’ve tried everything … : '(
