Full Proteus project with src in C AtMEGA8 for ds1990 iButton system.

说明：  STC15系列只用一个定时器的红外接收程序，有需要的可以看一下(STC15 series infrared receiving program with only one timer, you can see if you need it.)

基于卡尔曼滤波的MPU6050例程，效果很好。(Based on the Calman filter MPU6050 routine, the effect is very good.)

CAN通讯协议栈，完整程序包，基于STM32系统。简明易懂，是个学习的好基础包。(CAN communication protocol stack, a complete package, based STM32 systems. Easy to understand, it is a good learning base package.)

时间延迟系统的应用，方法和发展趋势，详细介绍了带时延的控制系统的研究理论和方法(Time delay applications, methods and trends systems, detailing the theories and methods of control systems with delay)

基于keil5开发的单片机stm32f407vet6程序，针对bin文件的USB导入程序(USB importer for bin files)

说明：  stm32f103c8t6 驱动0.96oled四角屏显示曲线，很好的绘制各种曲线(Stm32f103c8t6 drives 0.96 OLED quadrangular screen display curve, which can draw all kinds of curves well.)

单片机串口接收缓存队列的简单实现，由C语言实现，性能稳定，移植方便可靠！(Microcontroller serial port to receive buffer queue to achieve a simple, achieved by the C language, stable performance, reliable and convenient transplantation! )

本程序目的是提供使用stm32串口收发一帧数据的一种方法，采用中断方式接受和发送，每进一次中断接收或发送一字节，可以实现pc机与板子通信或板子与板子间通信。注意本程序中外接高速晶振为12M赫兹，而大部分板子为8M赫兹，本程序所用芯片是stm32RBT6(The purpose of this procedure is to provide a method of using STM32 serial port to send and receive a data, using interrupt mode to receive and send, every one into the time interrupt receiving or sending a byte, can realize PC and the communication or board and board communication. Note that this procedure the external high-speed crystal oscillator for the 12M Hz, while the majority of board is 8M Hz, the chip used in this procedure is stm32RBT6)
