一个使用USB下载51单片机程序的源程序，是第一手开发，很方便学习单片机的朋友使用-A use of 51 single-chip USB to download the source program is first-hand development, very convenient to study the use of SCM Friend

这个范例说明如何使用8051 的Port 1连接LCD显示器，PORT 3.3、P3.4和P3.5则连接到LCD显示器的控制线。程序执行时将显示出Hello Keil C和LCD display */-This example shows how to use the 8051 Port 1 to connect LCD displays, PORT 3.3, P3.4 and P3.5 are connected to the LCD display control lines. Program execution will show Hello Keil C, and LCD display* /

实现了有凌阳的外部中断进行技数，同时有2赫兹的内部定时器，以实现对外部频率的采集 -Sunplus has achieved the technology to a number of external interrupt, while Hertz has 2 internal timer in order to realize the acquisition of external frequency

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
