8９Ｓ51的程序，实现秒表功能秒表C51程序，包含键盘扫描，在数码管上显示各个数字，使用80C51单片机 -89S51 procedures to achieve stopwatch function stopwatch C51 procedures, keyboard scanning, digital control in the various figures show that the use of 80C51 microcontroller

一个基本的平安钟控制程序，帮别人写的，学习的人可以看看，不错的。-Ping

由ADC0809的IN0输入一模拟电压，经过A/D转换后，在三位数码管上显示转换后的数字量-IN0 input from one of the ADC0809 analog voltage, after A/D conversion, in the three digital tube display digital converted

实现层的隐藏与显示,功能比较完善,请大家一定要下下来好好研究-The realization of the hidden layer and showed that a relatively complete feature, please we must carefully study down under

这是一个就算波特率的软件，功能强大，在单片机通信时不用自己动手计算，只要用此软件点击一下，就能得到结果。-This is a software that even if the baud rate, powerful, in the MCU communicate without it-yourself basis, as long as the click with this software, you can get results.

内容：1、本程序用于测试4相步进电机常规驱动 2、需要用跳帽或者杜邦线把信号输出端和对应的步进电机信号输入端连接起来 3、速度不可以调节的过快，不然就没有力矩转动了 4、按s4（设置成独立按键模式）可以控制正反转 -Contents: 1, the procedure used to test the four-phase stepper motor-driven two conventional, need to jump cap or the signal output line of DuPont and the corresponding stepper motor signal input terminal connected three speed adjustment can not be too fast, Otherwise, there would be no moment of rotation of the four, according to s4 (set to form an independent key mode) can control the positive inversion
