介绍一种具有短信息无线通讯功能的低功耗嵌入式多参数监护仪，基于ARM7核的32位低功耗微处理器作为系统控制核心，采用源码公开的嵌入式操作系统IxC／OS—II，通过低功耗的16位单片机MSP430完成数据采集，可实现心电、血氧、血压、体温信号的实时监测。系统采用西门子MC35i无线传输模块，实现生理参数以SMS方式无线传输，具有轻便节能、安全稳定等优点(Introduce a short message wireless communication function of low-power embedded multi-parameter monitor, based on the ARM7 core 32-bit low-power microprocessor system control as a core, using open-source embedded operating system IxC/OS- II, through the low-power 16-bit single-chip MSP430 achieve data acquisition, can achieve ECG, blood oxygen, blood pressure, body temperature signals in real-time monitoring. Siemens MC35i system uses wireless transmission module, physiological parameters in order to realize the way SMS wireless transmission, with a light energy saving, security and stability, etc.)

说明：  在STM32开发平台下，通过定时器的时钟配置，进行的PWM互补带死区的方波对电机进行控制。(Under the STM32 development platform, the PWM complementary square wave with dead zone is used to control the motor through the clock configuration of the timer.)

stm32f4USB声卡设置，运行与测试等，开发平台KEIL,希望对大家有帮助(Stm32f4 handwriting settings, running and testing, development platform KEIL, we want to help)

This example provides a description of how to use the USART in Smart Card mode. The example gives only the possibility to read the ATR and decode it into predefined buffer.

A program to consicle very mad and good !! yes :

说明：  适用于stm32平台，已经过实际测试，测试模块为GY-906(It is applicable to STM32 platform and has been tested in practice)

Leave the network and children but rejoin

将遥控接收头接收到的按键编码通过数码管显示出来 能解码的遥控编码必须是NEC 的6221/6121/6222编码方式(The remote receiver receives the key code via the digital display of the remote control code must be able to decode the NEC' s 6221/6121/6222 encoding)

基于STM32F103的文件管理系统。移植了FATFS文件系统，从SD卡中读取JPEG与bmp格试图片，然后显示。并带有触摸功能(The file management system based on STM32F103.Transplant FATFS file system, the SD card read JPEG and BMP test images, and then display.And with touch function)
