FC3 Dot Matrix Programming
Posted: Wed Apr 25, 2012 9:56 am
Hello ,
I’m using PIC16F628A together with 3pcs shift registers (74HC164), to program scrolling message display on 7x5 dot matrix LEDs.
Attached is the circuit (simplified) that I’m going to patch up, perhaps you could point out how I should program the PIC to work with the shift registers to achieve my aim, To scroll message display in endless looping.
For example I would display scrolling the letter “C”, involving ‘ON’ the LEDs:
RB1C5, RB0C4, RB0C3, RB0C2, RB1C1, RB2C1, RB3C1, RB4C1, RB5C1, RB6C2, RB6C3, RB6C4, RB5C5.
Please advice how to program using FC3, thanks.
