javascript - 如何使用 websocket 和 fadecandy 服务器来操作 ws2812b 灯条
我们需要关于如何使用 websocket 和 fadecandy 服务器来映射 64 个 LED 灯条的帮助。
这是 fadecandy 服务器中的映射
服务器配置 JSON：
我们如何使用 fadecandy 服务器映射到 websocket？
python - 在 for 循环中选择第一个列表项
我现在拥有的是下面的循环，它依次点亮每根 24 根 LED 灯。
我想要的是以前点亮的 LED 在每次迭代时都保持亮着。因此，每轮点亮的 LED 数量都会增加一个。
我假设我可以简单地从列表的开头选择到第 i 个项目，如下所示。然而，这会返回一个“TypeError：'int' object is not iterable”。
我不太清楚为什么这不起作用。
虽然我已经引起了您的注意，但除了使用 time.sleep() 之外，还有更好的方法来计时这些循环吗？虽然我使用的是线程，但当 LED 模式发生变化时，睡眠仍然会导致一些延迟。
raspberry-pi - Set Brightness Fadecandy with rpi
I am making a project with neopixels, a RPI and a fadecandy.I am very new to all of this.
I have written some code because I want to make different animations on my neopixels. The problem I am facing now, I don't know how to change the brightness for the neopixels.
I tried some different things but I always get in conflict and I think it is maybe because I am using the fadecandy? I am also using the opc library.
I wanted to ask if someone knows how to change the brightness when I am still using the fadecandy?
Or would it be more easy to just change the project and use an arduino?
