Need help! i am doing 24CX16R dot matrix using PIC16F877A with 74LS595? Answered


You omitted to explain what your problem is.


just now i have started to work with dot matrix.
Some of my friends suggest to use 74LS595 to drive Column so i purchased PCB related to 74595 but i don't know how to drive row and how much current it takes

So suggest a circuit diagram
