Scott connection study using PSCAD simulation

Useful modding - a spectrum analyzer + clock. We came across two 5x8 LED matrix, virtually occupying five-inch drive bay, and I decided to make a spectrum analyzer based on their sound.

这是个温度检测程序，10K的温度探头，基于STM32F103(This is a temperature detection program, 10K temperature probe)

说明：  实现modbus 客户端的给功能，实现tcp通讯(Implementing the function of Modbus client,Realizing TCP communication)

说明：  51单片机4路AD采集模块，附件带源码.原理图等(51 MCU 4-channel AD acquisition module, accessory with source code, schematic diagram, etc.)

spi协议，分为几个文件块，以供调用，采用时钟芯片ds1302做例子，进行协议的实现，是c程序方面阅读。(spi agreement, the document is divided into several blocks, calling for the use ds1302 clock chip as an example, for the realization of the agreement is c procedures reading.)

说明：  STM32103 W5500 tcpclient

说明：  NEC协议的红外遥控器解码程序，程序占用资源少，在51等单片机上验证OK。(ir decode for NEC protocal.)

stm32f10x_stdperiph_lib标准外设库(stm32f10x_stdperiph_lib standard peripherals library)

如题所示，用于EMWIN5.22版本的开发需求，和一个比较有用的开发实例(As shown in the title, the development requirements for EMWIN version 5.22 and a more useful development example)
