FC3 Dot Matrix Programming

Post by oookey »

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.
Chan

Hi,
Although you posted long before nobody seems to reply and I have noticed that last night..If you are still interested i can help you obviously not in FCV3 as it is almost obsolute..you can check this in FCV5 free version....

I will make program in FCV5 and you can check that if satisfied can make one in FCV3...
