在STM32上实现点亮LED灯，按键查询，ADC操作，定时器操作等基本功能(STM32 basic function routine on STM32 to light LED lights, key query, ADC operation, timer operation and other basic functions)

能够实现stm32的按键输入然后控制LED灯闪烁I(Can implement the STM32 key input and control the LED light flicker)

硬件采用STM32 C8作为主控、两个红外传感器、蜂鸣器、LED灯，家居红外报警系统可以应用在实际场所。(The hardware uses STM32 C8 as the main control, two infrared sensors, buzzers, LED lights, home infrared alarm system can be used in actual places.)
