这是我用汇编语言编写的计时器程序，通过计算机发命令开始倒计时，其中也有其他功能，但主要是倒计时，比较好用，这是个小程序，穿上来了表心意...

非常之经典的MCS51程序,非常适合初学者-very classic MCS51 procedures, very suitable for beginners

通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。-Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.

用c语言串口接受数据的功能 在单片机中很实用！-C language accepted by serial single-chip data at a very practical!

本文档提供了用C语言写的单片机滤波算法，因为单片机尽管不擅长实现算法和进行复杂的运算，但在一些特定的场合，如实时动态测量等应用上还是要实现一定的滤波算法。-This document provides the use of C language written in single-chip filtering algorithm, because the realization of single-chip, while not good at algorithms and complex calculations, but in some specific occasions, such as real-time dynamic measurement applications or to achieve a certain degree of filtering algorithm.
