使用2543和C51单片机进行电压的实时测量

stm32远程升级例程（分为boot loader区，用户区，和ota区，用户可以根据不同的需求修改启动地址）(Stm32 remote upgrade routines (divided into boot loader area, user area, and ota area, the user can modify the startup address according to different needs))

串口1串口2互相转发对方收到的数据，串口2转发串口1收到的数据，串口1转发串口2收到的数据，stm32(Serial port 1 serial port 2 forward each other to receive the data, the serial port 2 serial port 1 received data, serial 1 forwarding serial port 2 received data, stm32)

NT7538测试程序,串行接口协议，使用内部升压(NT7538 Test code,Serial interface，use the internal resistors for charge up.)

C#与串口继电器控制开关代码,可与携光串口继电器交互控制灯、电机等设备

说明：  keil c51 单片机开发软件，，内含破解补丁(Development software of Keil C51 single chip microcomputer, including crack patch)

基于STC89C52rc做的一款温控风扇，该实物有ds18b20检测温度 可按键和红外控制 掉电后设置的上下限可在eeprom中保存 同时温度数据和档位可传输到蓝牙app中显示

通用的I2C的存储程序，把I2C的协议的每一个部分都进行了函数封装,非常便于移植到其他平台，

基于单片机计算器,可计算加减乘除，但是不能计算小数(Based on single chip calculator)

基于M0518单片机的摇头灯加减速处理，细分算法，PWM线性调光(Moving head light, deceleration processing, segmentation algorithm, linear dimming PWM)

这是我认为51汇编里面比较好理解的书籍，以及我简单整理的汇编指令文档一份。入门学习还是不错的。(This is a book that I think is better understood in the 51 assembly, as well as a document of assembly instructions that I simply organized. Initial study is still good.)
