说明：  基于单片机的指南针毕业设计，精度高，可行性较好(Compass graduation microcontroller-based design, high accuracy, feasibility)

this code used to calibrate the touch of tcb8000c TFT screen with pic 18f4620 micro controller

本代码为STM8S903K 无刷无感电机的驱动源程序 应用在电动工具上 属产品级代码 用电位器调速 保护电流40A(The code STM8S903K brushless non-inductive motor drive source Is a product-level code used in power tools speed control potentiometer protection current 40A)

说明：  里面有手册和资料，有STM32的简单控制舵机和LED的程序，用的IO口仿I2C(There are manuals and materials in it. There are simple procedures for STM32 to control steering gear and led. The IO port used is similar to I2C)

C51控制AD9833实现程控波形发生器，在keil5上即刻运行(C51 Controls AD9833 to Realize Programmable Waveform Generator)

51单片机考勤系统下位机程序，可以配合上位机软件实现考勤功能，将hex文件下载到51单片机即可使用(51 MCU control procedures can be achieved with the PC software attendance function, the hex file into the microcontroller 51 can be used)

STC单片机IO口模拟RS232测试程序,Keil Cx51应用开发技术中的程序主要的功能是在利用串口调试工具发送一个8bit的数据，而后单片机接收后把这个数据发送给模拟串口(STC Single-chip analog IO port RS232 test procedures, Keil Cx51 technology application development process is essentially the function is in the use of serial debug tools send an 8bit data, and then after the single-chip receive the data sent to the simulation of serial)

ymodem功能的BootLoader，基于stm32，可直接使用 (Ymodem function of the bootloader, based on STM32, can be used directly)

说明：  适用MINI板的基础例程 STM32奋斗板-触摸屏(Basic routines applicable to MINI boards)
