hey, im currently working on a project with 7x5 using PIC microcontroller. I need to scrolling texts in 7 cascaded 7x5 dot matrix displays. Does anyone have any sample codes or algorithm for it? I already did something which displays 5 characters in 3-7x5 but it just wouldn't work if the 7x5 is already 7. What my program is doing to to just turn on one of the 35 columns at a time and send the coresponding bits on the rows. If you want to see my code and see what's wrong, I'll be very glad to show it. Thanks!
