基于ATMega64编写的BOOT升级程序，通过固定协议进行通讯，接收到的程序保存在外部Flash中，进行搬移(Based ATMega64 prepared BIOS upgrade program, through a fixed protocol for communication, received program stored in the external Flash, make the move)

按键控制，检测独立按键，单片机读取状态口，控制相应的LED灯(Key control, testing the independent button, the microcontroller reads the status port and control the corresponding LED lights)

说明：  自己画的开发板，用的STM32F103VGT6芯片，代码中使用了很多功能，基本的I2C，SPI，Flash读取，串口通信（WIFI，Enocean协议），等都有涉及，驱动代码不全是自己写的，所以有些地方没去在意备注，但是每个使用修改的地方都有我自己的备注，基本上就是自己的开发板，自己在研究学习验证的过程中一点一点整合起来的(I drew my own development board and used stm32f103vgt6 chip. Many functions were used in the code, such as basic I2C, SPI, flash reading, serial communication (WiFi, enocean protocol), and so on. The driver code was not written by myself, so some places didn't pay attention to the remarks, but every place I used and modified had my own remarks, which was basically my own development board In the process of research, learning and verification, I integrated them bit by bit)

说明：  Infrared tracing, OLED display real-time movement time, PID adjust seesaw, mobile phone display car time.(Traceable, OLED display)

saber仿真模型 主要功能实现了spwm的并网仿真 (saber main function of simulation models and network simulation spwm)

STM8S控制五线四项步进电机正反转程序。(STM8S control five line four stepper motor program.)

说明：  8*8的矩阵键盘程序，是很好的代码喔。键盘程序采用的是查询的方式来写的喔。(8* 8 matrix keyboard procedures, is a very good code. The keyboard is used for writing.)

c8051f020的24c02程序，经测试验证可以使用。(c8051f020 of 24c02 procedures, verified by testing can be used.)
