Hello,
Please refer to the attach pdf, showing my setup sketch for the purpose of matrix display.
I got stuck at entire row of the LEDs lit up, and blinking ON and OFF all together. For example I failed to specifically ON the LED at RB1 and C4.
I could keep the row RB1 ON, but how do I control the shift register to ON C4 at the correct time? The shift register will always start from the 1st bit then shift to next bit on the next clock.
I need your pointers and advice.
Thanks for your time.
