51 single chip microcomputer "breathing light" program-EEWORLD

Collect

I just watched a video about light cube and the term "breathing light" was mentioned one-sidedly. I hurriedly wrote a breathing light program with a digital tube to display the brightness change. The integer frequency is the parameter for adjusting the breathing frequency. The attached figure is a temporary gif file. It will take a while to see the effect./*12Mhz??§????*/
