> This code is supposed to repeatedly send 'hello' to the screen, and outputs > a roughly 2.4Khz square wave to PORTA,0. The 2.4Khz tone is produced (so I > know the PIC is working), but the LCD does not. Start with _really_ long delays in you init routine like 100ms. You will probably find that it springs (well, oozes) into life and you can then go back and chop the delays back to more practical values.
