自己编写的,同时包含服务器端(使用Arduino C编写)和客户端(安卓app使用App Inventor编写)。因为买esp01的继电器模块带来的程序根本用不了,随即写了这个大通用版本,可以利用它通过Web方式控制任意IP的任意GPIO,支持各种电平触发模式,绝对好用! 免费开源,配套博文在https://blog.csdn.net/safirst/article/details/128920304
买那个模块商家没有拿到合适的代码,经过研究自己编写出来的程序,可以利用esp8266控制器.apk 来控制继电器。4个按钮分别对应着两个IO口的高低电平触发,用了就知道了。
The Device Tree (DT), and Device Tree Overlay are a way to describe hardware in a system. An example of this would be to describe how the UART interfaces with the system, which pins, how they should be muxed, the device to enable, and which driver to use. The original BeagleBone didn't use the DT, but the recently released BeagleBone Black was released with the DT and is now using the 3.8 Linux Kernel.
