Hello all,
After several problems, I finally have gotten my lcd and Pic to talk and display something. I have a program that just writes text to the screen with 500 and 1000ms delays between each line of text. However when it runs I only get part of the text, and mostly just jumbled characters. Most of the text i have in the program doesnt display at all, and when it does, it is in the wrong row and has all sorts of weird characters mixed in with it. I did have a 6 inch cable going from the pic to the lcd. I thought maybe since each pin on the pic only puts out 25mA, I would try making the cable only an inch or two. After doing that, what was displayed on the lcd was a little more accurate, But im still getting garbage. Right now, I have the whole circuit on a bread board with a 4mhz crystal, would it work better after soldering it together on a perf board?
Any ideas would be greatly appreciated!
Thanks,
Scott
