Hi.
Im having problems with my LCD. It seemed to work perfectly, but now Im having issues with it having now properly tested it. I have two 16x2 LCD's and they both do the same thing. I plug the board in, and it seems to work to start with, but then the lcd just fills up with solid blocks. It does this one block at a time, and sweeps across the top row, then fills up the bottom, until the entire LCD is filled up with solid blocks.
What causes an LCD to do this, code, lack of power? dataline connection, rs/e connection?
This is for my Uni project which is to be handed in at the start of next week. Please please please help.
