64*64 RGB LED Matrix #319

Hi Hzeller, I was really impressed with data in your git repository. It really helps people who want to control the LED matrix. I am currently working on a 64 * 64 matrix. To do this, I designed and tested an adapter board (active) based on your data. I used 220V/5V AC/DC adapter for LED Matrix. Adapter board is supplied from the RPI2.

The path of the test code is as follows. Https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/python

As a result of this code, the image was initially displayed correctly. However, the screen wanes sharply even after 3 to 5 seconds. I also run your demo-main.cc, but the result is the same. I used your sample as it is. I think there is something I can not think of.

I want you to help me solve quickly this problem. I will wait for your good reply. I'm so sorry to have taken your busy time. But I believe that you will help me.

Best regards!!! anatoli.

Did you read the Troubleshooting section ? Image going away typically means that you have something that also fights for the GPIO pins, so make sure to

Thanks for your effort. I solved this problem. I have not removed dtoverlay=w1-gpio in /boot/config.txt The one-wire protocol was enabled (w1-gpio). So I disabled it. Then the LED works correctly.

Thanks for your help.

Best.
