I've already soldered the 0Ohm ressitor onto the I2C jumpers, my concern is that I may have damaged the board, and I want to know if that is possible. Because I've trying to send commands to the screen and it just displays Matrix Orbital logo.
Here is the code of my program for a Motorola HC908JL3E ...
