让两个ESP8266相互问好是一件很有趣的事情,这需要将一个ESP设置为接入点(服务器),另一个设置为基站(客户机),绕过它们建立无线通信,让客户机向服务器发送一条“Hello World!”信息。 项目零件BOM很简单:ESP8266-01、FTDI编程器、连接线。电路图很直观 ...
随着现在物联网设备的而越来越多,现在市场上出现越来越多的物联网设备,其中 ESP8266 是最受欢迎、价格便宜且易于使用的模块,它可以将您的硬件连接到互联网。 今天我们就以ESP8266和STM32来实现一台网络服务器,我们使用 ESP8266 将 STM32F103C8 连接到互联网。
We’ve written lot about the ESP8266 lately, but people keep finding more awesome uses for this inexpensive module. [Martin] decided that using the ESP8266 with an external microcontroller was overkill ...
Since the Wemos D1 can't directly measure internet speed like a PC, it can simulate a speed test by: Downloading a file or data from a server. Measuring the time taken. Calculating speed = size / time ...
This project includes a Flask server with an interface for upload a binary file which will be available in a route to be download. The other part is the code for an Esp8266 to check the version ...
我并没有使用CubeMx,我使用的HAL代码进行的初始化。大家可以获取我的模板资源。 void dht11_read(uint8_t *result); void dht11_read(uint8_t *result) #define ESP8266_TX_BUF_SIZE 64 #define ESP8266_EOK 0 #define ESP8266_ERROR 1 #define ...
编译并下载程序,上传固件至mini D1 WiFi模块。 上传成功之后显示如下: arduino上阿里云所需要用到的四个库文件。PubSubClient ...
瓦力号是一台自走车,可利用 WiFi 联机以及 IR 红外线控制,其主要是透过 NodeMCU这块主控板来实现 WiFi 联机控制。 在这个专案里将program 刻录进 NodeMCU,利用 WiFi 连网,并设计一些供用户按的按钮,用来操控自走车。 材料 1. 伺服马达:伺服马达是回受控制系统 ...
It has never been easier to build displays for custom data visualization than it is right now. I just finished one for my office — as a security researcher I wanted a physical map that will show me ...
