用simulink搭的离散PID，可以用自动生成代码再下载进单片机运行(With simulink take discrete PID, can be used to automatically generate code and then downloaded into the microcontroller operation)

08c51单片机，基于超级终端的前后台控制系统(super HyperTerminal)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

用STM32驱动单片驱动MS9607温湿度压力传感器读取温度湿度大气压力(use STM32driver MS9607)

有源滤波的介绍，文中详细介绍了几种有源滤波电路图(The introduction of the active filter)

同时使用STM32三个串口的接收与发送，串口1使用printf(),串口2使用u2_printf(),串口3使用u3_printf().接受采用定时器中断超时，5ms未接收到数据认为本次接收结束，置位相应的标志位，主程序检测并处理接收数据。(STM32 simultaneously receive and send three serial, serial port 1 to use printf (), 2 serial ports use u2_printf (), 3 serial ports use u3_printf (). Accepting timer interruption timeout, 5ms does not receive data that the receiving end of this, set the appropriate flag, the main program to detect and process the received data.)

51单片机MODBUS通信一例 ，读者可以通过单片机与一切具有MODBUS通讯协议的智能设备进行通信(51 single MODBUS communication example, the reader can communicate with all intelligent devices through the SCM has MODBUS communication protocol)

此编成是使用STM32 的DMA读取写入EEPROM内的资料(STM32 DMA read and write EEPROM)

SLE4428逻辑加密卡驱动程序源码， C语言实现(sle4428 logic encryption card, driver source code, c language)

stm32双串口实验，调用串口2接受信息然后用串口1转发。主要参考意义在于两个串口的配置。(Stm32 dual serial port experiment, call the serial port 2 to receive information and then use the serial port 1 forward. The main reference is the configuration of the two serial ports.)
