基于STM32F1的RFID M1卡的读写程序，RFID芯片是NXP的RC522(Based on STM32F1 RFID M1 card reader program, RFID chip is NXP s RC522)

说明：  msp430f5529通过输出PWM波控制舵机(Msp430f5529 control steering gear)

基于电压正反馈的逆变器并网孤岛检测技术，simulink仿真有较好的介绍，是学习孤岛检测的好资料。(Based on the positive feedback voltage inverter grid islanding detection technology, for a better introduction to simulink simulation.Islanding detection is learning good information.)

本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)

说明：  Wiegand 26/34转RS485、RS232信号转换模块（原理图+PCB+BOM）,输入韦根信号，转换为串口输出(Wiegand 26/34 to RS485, RS232 signal conversion module (schematic + PCB + BOM), input Wiegand signal, converted to serial output)

单片机的A/D采集模块，该模块通过编者使用，性能良好稳定。(Microcontroller A/D acquisition module, through the editor to use, good performance and stability.)

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)

增量式PID控制直流电机基于STM32的(PIDIncremental PID control DC motor based on STM32)

搞了十几天，终于实现了无线模块NRF24L01可以发送和接收到一串字符了，本程序含发送程序，和接收程序，单片机用AT89S52,把显示的字符串显示在1602上(Out of the 10 days, finally achieving a wireless module NRF24L01 can send and receive a string of characters, and this procedure with sending program, and receive program, microcontroller use AT89S52, the display on the string displayed in the 1602)
