I need help in displaying scrolling text in 7-5x7 led displays using PIC16f84a or PIC16f877. Does anybody has an algo for it?? Or sample program +schematics? Please. I really really need help. I've been working for weeks now but I just couldn't get the right technique.
I've been through that but I actually can't understand coz most are for atmel and the sites posted there have no hardware schematics so I can't understand. If someone can explain it I'll be very thankful!
Can I know your design? I actually did it with pic16f85 and 4017 but it only worked for 1 5x7 and I need to scroll the text in 7 pcs of 5x7. Can you help?
