I've been trying to programme a LCD (HD44780) with a PIC, (16f84A) but come across a problem I'd like to share with this forum. I have managed to initialise the LCD and got it to write 'HELLO'. But unfortunately it continually repeats this, even though my program should lock-up. I have checked the reset pin (MCLR) but have that held at 5V. I've messed around with the command control codes, but that does'nt appear to make a difference either.
Any input into this problem would be much appreciated.
