hi,
I have just started learning how to use pics and have been following nigel goodmans tutorials. I am upto but am having problems.
When I turn on the circuit all I get is a line full of black squares (just the top line). I have tried to register on his forums to ask for help but am still awaiting confirmation.
I have looked around these forums for similar problems and think that there could be 2 possible reasons for this.
The first reason is that I am not using a hitachi 44780 lcd. I am using this lcd which uses a Samsung KS0066U controller but have since read that this should be compatible with the 44780?
The second thing I have read is that it could be because I am using a LVP programmer, but there should be ways around this where I can still use my home made programmer?
Any help would be appreciated
