8X8 LED DOT MATRIX SCROLLING TEXT

Post by BLACKROSE »

Hello to all!
I would like to send a scrolling text to 2 led dot matrix displays 8x8 . I use a code (attachment) to send characters to an lcd 4x20 with modbus protocol. What modifications must do to that code to put 2 led matrix displays 8x8 instead of lcd 4x20 ? I'll use a shift register 74HC164 and a ULN2803 for columns . How can I connect microcontroller-shift register ? The example of LEDMatrixparallel component don't help me to wire above chips with MCU. Thanks.
