Hi Dave,

I'm not sure I understand you correctly. Chip is running, I put LED on all data pins D4-D7 and R/S as well and it blinks 0.5s interval (some of them didnt blink, just keeped HIGH). I also tried to start-up PIC later than LCD to get LCD powered properly, but still the same.

I use internal oscillator on 4MHz. This is the first time I use LCD, so please excuse some misunderstandings.

Thank you,
Pavel
