这是我用C语言写的一个数字钟，他可以实现多种闹钟和秒表功能-This is because I use C language written in a digital clock, he can achieve a variety of alarm and stopwatch functions, etc.

51上的RTOS，该RTOS为非占先式多任务操作系统，如果用户任务的最长执行时间小于 系统节拍时间，则本MiniRTOS要优于占先式TOS。因为本MiniRTOS占用资源小，RAM不超过20字节，程序空间只占为600多字节。-51 on the RTOS, the RTOS non-preemptive multitasking operating system, if the user of the longest task execution times smaller than system beats time, it is superior to the MiniRTOS Preemptive 200040. Because of the small resources MiniRTOS occupation, RAM no more than 20 bytes, procedures only for the space of more than 600 bytes.

这是关于DS18B20的读写程序,数据脚P2.2,晶振12MHZ温度传感器18B20汇编程序,采用器件默认的12位转化,最大转化时间750微秒特点能精确到0.5摄氏度-DS18B20 on literacy, data P2.2 feet, 12 MHZ crystal oscillator temperature sensor 18 B20 compilation procedures, devices using the default 12 conversion the largest 750 microsecond conversion time characteristics can be accurate to 0.5 degrees Celsius
