说明：  关于利用TCT40-16ＦＳ进行超声波测距的原理图，实物图，源码，看完之后对超声波测距将不再陌生．(Conducted on the use of ultrasonic ranging TCT40-16FS schematic, physical map, source, after reading will not be a stranger on the ultrasonic ranging.)

以前做的一个仿真，关于空间矢量控制的，看看能不能给有需要的人！(Ago to do a simulation, on the space vector control, can look to those in need!)

利用定时器1的互补通道实现SPWM（图形测试实现一半）(Implementing SPWM with complementary channels of timer 1)

有关 C语言的CRC校验的资料，很实用，值得收藏和学习(About the C language, the CRC data, it is practical, it is worth collecting and learning)

基于51单片机的超声波测距模块使用，使用HC-SR04模块，定时器测量回波长度(Ultrasound Ranging Module Based on 51 Single Chip Microcomputer)

单片机的40个实验，这个很全的，是一个很好的东西，希望大家好好使用它。(SCM 40 experiment, this is very full, is a very good thing, hope everyone to use it. )

将正负5v电压 转换成对应 pwm信号(The positive and negative voltage into the corresponding 5v pwm signal)

控制系统，自动化专业经典教材《非线性系统》英文第三版(Control systems, automation classic textbook " nonlinear systems" English Third Edition)

说明：  在freertos操作系统下采用modbus协议进行rs485通讯(485 communication using Modbus protocol under FreeRTOS operating system)

单片机串口发送程序，试一次课设做的，非常非常好用(Chip serial transmission program, try again Lesson set, very, very easy to use)
