    hi everyone ,,hope  i will get some help ,,as i am unable to print I alphabet on 8*8 led matrix (Scrolling) where i have used two 74hc595 one for column and one for row,,,with arduino it works,,,but my task is to do this scrolling with PIC16f877a, hope some will surely help me .above is my code'

thanks is advanced
