Dear Sir/Madam,

I am writing to inform you of an issue I am experiencing with the “Pironman Raspberry Pi 4 Case” and the “WS2812 RGB Strip”. I have installed a Raspberry Pi 3 into the case, but the colors of the RGB strip are not displaying correctly. For example, blue is showing as green and there are many gaps where nothing is lighting up.

I would greatly appreciate it if you could assist me in resolving this issue.

Thank you for your time,

1. Please confirm whether the wiring of the RGB light strip is correct and whether the jumper cap is connected properly.

2. Please provide us with photos so that we can understand the situation

3. Run the following command to check if there is any error message: sudo pironman stop && sudo python3 /opt/pironman/main.py

Good morning:

to 1) I think everything is connected correctly

to 2) I made a video where you can see the assembly and a boot process. The video is too big for the forum hence an external link.

[[Cloud](https://c.gmx.net/@324822690248523891/WFmogNyRT7eqM1XCffBCGw)](boot video)

to 3) the output

1. We only tested on Raspberry Pi4
2. The Pironman RGB light needs to use hardware PWM, which conflicts with the PWM used by Raspberry Pi audio. Comment out the dtparam=audio=on in the /boot/config.txt file, and the RGB will be normal.

thanks, it looks good now
