First off, Hello World leaves a little to be desired. There is no feedback if an error is raised, not even a provision for one, although I haven't searched it's library. He doesn't seem to know a potentiometer/rheostat from a resistor!
Anyhow, I'm stumped. I hooked everything up after testing my board (failing 3 pins) and nothing. If it means anything, I have not attached a "10k resistor" to the LCD VO, because it was completely blank, couldnt use any lightening up.
The package had a footprint on it but no cracks I can see. Not much more than 150psi anyhow...
says it's hitachi HD44780
Is there another starter LCD sketch?
