Topic: Chinese 8x8 with TM1639 (Read 1 time) previous topic - next topic


I got a 8x8 dot-matrix with TM1639 controller. I was not able to find some readable datasheet on the internet, so, here is a small help if somebody is trying to figure how to control it.

Strange on this is, that you can not push there whole 8bit (row), you need to divide it into 4 bit. I don't know if I am doing something wrong, but now, it's working. Also, I put there an rotation of 90 degree. You can also set brightness in 7 steps.

If somebody will create an "normal" library, I would appreciate that :)


Sounds like you already have a working code base so producing a library from it would be trivial.

The chip is split into 4-bit chunks. And it works quite similar to max7219.
