stm32系统文件，可以方便实现移植操作-stm32 system files

STM32开发板实验的系统文件代码，主要为了配置系统时钟与外设配置以及各外设的用法-STM32 development board serial experiments code system files, mainly in order to configure the system clock and peripheral configuration

基于STM32的M3-uCOS-II 多参数传感器开发文件，完整的工程文档，可检测CH4、CO、温度等参数，包含真人语音、AD5207、485、红外、eeprom等等，原创误转载-Based on the STM32 M3-uCOS-II multi-parameter sensor development documents, complete project documentation, can detect CH4, CO, temperature and other parameters

成功移植了contiki操作系统的代码，编译在keil5下编译生成HEX文件下载到STM32即可实现LED闪烁与串口打印功能。(The code of Contiki operation system is successfully transplanted, compiled and compiled under keil5, and HEX files are downloaded to STM32 to achieve LED scintillation and serial port p
