CMSIS + STM32_USB-FS-Device_Driver + STM32F10x_StdPeriph_Driver(CMSIS+ STM32_USB-FS-Device_Driver+ STM32F10x_StdPeriph_Driver)

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.)

数码管是一种半导体发光器件，其基本单元是发光二极管。数码管按段数可分为七段数码管和八段数码管，八段数码管比七段数码管多一个发光二极管单元，也就是多一个小数点（DP）这个小数点可以更精确的表示数码管想要显示的内容(The digital tube is a semiconductor light emitting device. Its basic unit is a light emitting diode. According to the number of digital tube can be divided into seven digital tube and eight digital tube, eight digital tube seven segment digital tube more than a light emitting diode unit is a decimal point (DP) of the decimal point can be a more accurate representation of the digital tube to display the content)
