Hi all.
I've recently bought a 4x20 LCD panel based on H44780.
It took me a while to get it up and running (I use a 16F627 and didn't realise that RA5 is input only, and that init procedure is wack!).
I now can write text to the display, and I wrote a small test-program that spews data to the panel. When I start it, line 1 gets filled, and the line 3, but nothing ever appears on line 2 and 4? Eventually, line 1&3 wraps.
Any ideas? Phrphrphrphrphreeeease?!?
