PN532在STM32上的读写器模式，能读写普通卡的UID，并通过LCD进行显示UID(PN532 on STM32 reader mode, you can read and write ordinary card UID, UID and displayed via LCD)

用于实现单片机16F648A和微控制器的通信。通过回车来确定通信是否成功，成功了可以从对应的LED开关看出，同时电脑终端会出现正确或错误的回复(This program is designed to convert 16F648A into a working micro-controller system which waits for one of a number of Carriage Return terminated messages and turn on or turn off one of four LEDs corresponding to the message. If the message is decoded successfully, an OK will be sent to the PC, otherwise an Error message will be returned )

说明：  STM32最小系统设计的原理图和PCB，整体尺寸和各部位大小都已经标好，按这个样子是可以规模生产的。附带PCB的库文件。(The schematic diagram of the STM32 minimum system design and the overall size and size of each part of the PCB, have been marked so that it can be produced on a large scale. The library file that comes with PCB.)

stc89c51+ds18b20+lcd12864,在液晶上显示温度曲线，并在同一界面实时数显温度值，用keil3以上版本(stc89c51+ds18b20+lcd12864,Displayed on the LCD temperature curve, and at the same interface and real-time display temperature, with above keil3 version)

STC1256xxAD系列MCU实现8路PT100温度巡回检查程序，温度过高或过低报警。(STC1256xxAD Series MCU achieve 8 PT100 temperature roving inspection procedures, high or low temperature alarm.)

AD7705驱动程序，通过51实现，希望有用。(AD7705 driver, 51 achieved by the hope that useful.)

说明：  keil编程，可以使单片机计数，可加减基础数值，附带流水灯(Keil programming, you can count the microcontroller, can add and subtract basic value, with water lights)

使用STM32F103C8T6作为主控的ST-Link固件(ST-Link firmware using STM32F103C8T6 as master control)

AD9954驱动程序，主控为CPU为STM32，包括单一模式，线性扫面模式，RAM模式，可以产生AM,FM,ASK,PSK,FSK调制信号(AD9954 driver, master for CPU is STM32, including single mode, linear sweep surface model, RAM model, can generate AM, FM, ASK, PSK, FSK modulation signal)

STM32接收gps网络时间，并通过GPRS发送(STM32 receives GPS network time and sends it through GPRS)
