RPi Zero + Grove LED Ring - Only half of ring working


I’m trying to get the LED Ring to work with my RPi zero + Grove Hat zero. Sadly only half of the LED ring is working. I got a second pice to make sure it isn’t a defected ring…

I also posted on Github, but got no answer… CircularLed Python Lib · Issue #31 · Seeed-Studio/Grove_LED_Bar · GitHub

Any hint?

Hi Khaos, I’m sorry that you have such a problem. According to your description, I guess the hardware circuit should be fine
