如何通过OSC消息打开/关闭Neopixels LED动画

Question

目前，我正在尝试弄清楚如何使用OSC控制Adafruit Neopixels条。更具体地说，我正在使用touchosc从我的nodemcu ESP8266微控制器上通过wifi发送/接收消息，并连接到我的neopixels。

我已经下载了其他人制作的测试代码，该代码聆听了OSC消息，以切换NodeMCU板上的小LED。当控制器收到消息时，它将消息发送回触摸osc客户端以判断灯是否打开(这是一个切换按钮(。这一切都很好。

我编写了一个简单的功能，可以将连接到NodeMCU板连接的Neopixel LED带动画。

本身也可以很好地工作。

我一直在努力的是找出一种方法来获取我的功能[称为gwblink((]在LED打开时在循环中运行。

。

我已经附加了代码。有人可以告诉我我在做什么错吗？我将永远感谢任何帮助！！：(

对于打开板上的小LED，此代码实际上可以正常工作，但是我的动画功能没有触发。

我只是在短时间内与Neopixels合作，但是在尝试使用它们时，我遇到了问题。串行监视器同时。一旦我禁用了序列命令(//serial.begin(115200(; (，它们工作正常。文档并不清楚地说明，我在一个线程中发现了它，在该线程中，Adafruit管理员在尝试将Neopixels更新为"痛苦"的同时提到了使用串行。

如果评论序列号。开始解决您的问题，那么我想您可以尝试：

*if (Serial.available()) {
int inByte = Serial.read();
Serial1.print(inByte, DEC);
}*

... idk，但值得尝试。
