基于80C51单片机源码公开的操作系统1.20.2 版RTOSsmall_rtos1.20.2-80C51 microcontroller based on the open-source operating system version 1.20.2 RTOSsmall_rtos1.20.2

状态1：正常时，8个LED发光二极管（彩灯）循环点亮。 • 状态2：有报警时，蜂鸣器发出报警声（用P3.3接一个按键，模拟产生报警信号。当开关合上，发生报警；当开关断开，报警停止。用P3.7输出音频信号驱动扬声器，作为报警信号），同时8个LED发光二极管（彩灯）闪烁。 P3.2接一个按键，用于消除报警-Status 1: normal, eight LED light-emitting diodes (lantern) light cycle.
