How to modify, and use Hal_ LED color

ok good - glad I could help a bit.

也许您理解错了我的意思，我的意思是在软件的界面中改变颜色

I think you can do this without writing code. That is, you can find software that's convenient for this. It seems that now you know what to use without coding. As far as I know, there are detailed descriptions of switching modes, colours, brightness, and so on in the instructions for light bulbs from different manufacturers. For example, I moved my car lighting bulbs to a modem. Before that, I couldn't even imagine such an idea would work. In the instruction, I read where I can use it. Would you believe that these LEDs work perfectly in a modem? Anyway, I don't know how the code will change when using LEDs from different manufacturers. I always thought that the main thing in the code is your code, not the name of the device you want to upgrade.
