Greetings dientudong,

I have moved your post to its own thread to give it better visibility to the forum community. It is best that you post your questions in their own dedicated threads rather than tacking it on to an existing thread.

Some additional information would be helpful - the microcontroller, the LED matrix, and the schematic. Your problems might be hardware related.
