Hi everyone, I hope I can get some help on this great forum! =)
I have recently moved from PIC16F18 to PIC18F458, and I have remade one of my old programs for testing with the new processor. The program is supposed to write som text on a standart HD44780 LCD, and it worked fine on the 16F84. When I now connect my LCD to 18F458, the screen shows the last to symbols of the text string in the start of line 1, the screen also flickers in a wierd way, and the cursor is blinking, although I turn it off in the program. Sometimes when I get my fingers close to the processor, or the quartz crystal the screen goes baserk and starts writing some nonsense on both lines (still flickering). I don't know whats worng, since I have everything correctly connected and everything. I don't think, that it could be the program, because I tried with the simpliest thing (two flashing LED's) and it also worked out kindda wierd...Any ideas? Thanks, any help will be appreciated!
Regards Denis
