Hi!

I was dreaming of connecting LED matrix to drive via nodemcu.

I have similar one:

https://www.solidrop.net/product/f3-75- ... i-top.html

I found this progect for arduino:

http://www.instructables.com/id/64x16-RED-LED-Marquee/

But it has hardware timer based code which i don't really understand so i can't rewrite it. Like:

Code: Select all

  TCCR2A = 0; TCCR2B = 0; TCNT2  = 0;
  TCCR2B |= (1 << CS12) | (1 << CS10);     // Set 1024 prescaler
               // 160Hz scan rate = 10 frames/second (16 pairs of rows)
  OCR2A = 97;  // 97 = (16,000,000 / (1024*160)) - 1
  TCCR2A |= (1 << WGM21); TIMSK2 |= (1 << OCIE2A);

If there is some one who can help me with it?
Or is there already a solution to drive this kind of LED matrix?
