I am using the CFAH2002A-NGG-JP with the melabs LABXUSB dev. board. I know the hardware is OK, because I loaded a demo hex file and the display works. I am programming in c using the microchip mcc18 compiler and the lcd library. the target chip is an 18F4455 running at 20MHz. The library function doesn't work, so I wrote my own functions. The display seems to init correctly (it clears), but I cannot seem to write any characters to it. This ought to be the simplest part! Thisis driving me nuts! Do you have any example c code or an algorithm. The datasheet I have only shows the init flowchart. I must be missing something.
