4x4 RGB Multiplex Flicker problem

Other Hardware LEDs and Multiplexing

Hi tansel and welcome,

Suggest you get rid of your shiftOut() function and replace it with the standard Arduino shiftOut() function.

Next, looking at this part:

  for(int j=0;j<12;j=j+3)
  {
    Tlc.clear();
    Tlc.set(j, 4095);
    Tlc.update();
  }

Should the Tlc.clear() and Tlc.update() really be inside the loop?

Lastly, when does your sketch ever use dataArray[1] to dataArray[4] ? Are they not supposed to be part of the multiplexing sequence? I think you have a little more code to write!
