it happened for me
dont have a scientific reasons for the failure
i was just interested why you are suffering ?
i wanted to simulate the entire set up here with only controller side
I've also attached some pictures of the layout on the breadboard. You can see the single top left sqare blinking during one of the hex file tests. I also got some more PICs in today and tried a brand new one along with the one I had. Same result.
I don't know what's going on with this. I read a lot about this stuff and it is all supposed to be really simple.
I tried the pic element on breadboard again. I felt it, a question of one or other wires not connecting properly in the breadboard.
I suppose that you have used thiner wires as he recovered from some cable.
I too had inconsistency of wires. After I sorted them, it worked nicely. I took two photos one with authors name and second showing the results
Thus it works on original software, only thing you need to do is have a 10 ohms from display contrast pin3 to ground.
why not go ahead with a board, that has the LCD connections in order and wires placed properly, in the artwork.
I did notice some of the voltages were fluctuating. So it does appear to be electrical noise causing this? Do my connections seem to be right on the breadboard?
I ordered some .1uF caps yesterday. I should get them today or tomorrow. I will also try some thicker wires for the LCD.

So what are you guys suggesting I try to get this working? Is my layout ok, if not what is wrong with it? Should I not be using a breadboard?
I'm stopping by the store to get some 22 gauge stranded wire to replace the wire on the lcd and some 24 gauge bus wire for when I make my proto board. Also picking up some .1uF caps to put in between +5v and ground on the chip.

hi,
I would use the pcb for the project, the layout looks correct.
I am assuming from your pcb image that the copper track is on the other face of the board and that we are looking thru the board to the track.???
