说明：  西门子ppi通讯，新人上传的第一个代码，请多关注，谢谢大家了(Siemens PPI newsletter, the first code uploaded by newcomers, please pay more attention. Thank you.)

说明：  课程：微机接口技术 课程设计题目：单片机最小系统(Course: Computer Interface Technology Curriculum Design Title: Single-chip minimum system)

串行da模块的应用，和单片机通信，通过单片机控制da模块(Serial da module application, and single-chip communication, via da MCU control module)

说明：  本实验将实现如下功能：本章我们在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(This experiment will achieve the following functions: in UCOSII, we create three tasks: start task, LED 0 task and LED 1 task, start task for creating other tasks (LED 0 and LED 1), then hang up; LED 0 task for controlling the brightness of DS0, DS0 80 ms per second; LED 1 task for controlling the brightness of DS1, DS1 300 ms. 300 ms, cycle in turn.)

stm32单片机使用sim900a模块进行gprs通信(the stm32 Microcontroller use sim900a module gprs communication)

说明：  当温控开关打开时，若测得环境温度大于设定温度，则继电器吸合 启动电机工作；若测得环境温度小于设定温度，则继电器释放， 电机停止工作；(When the temperature control switch is turned on, if the measured ambient temperature is higher than the set temperature, the relay will suck in. Start the motor; if the measured ambient temperature is less than the set temperature, the relay will be released. The motor stopped working.)
