MC9S12XEP100的程序，适合中低级程序员练习(MC9S12XEP100 program, suitable for junior programmers to practice)

使用51单片机以及红外管，这段代码实现小车沿着黑色线路准确行走，但是要自己修改到合适的左右轮速度才能完美转弯。(By using 51 MCU and IR LED light tube, the code can achieve the goal of moving according to the black line. But you need revise the speed data of the left and right tire so that the car can turn aroud perfectly. )

高精度电压表(24bit) VB源程序,简单修改可实现多量程(precision voltage (24bit) VB program, a simple change can be realized more range)

可实验0.5KHZ到10KHZ的简单测频,并由数码管显示出来!(Experimental 0.5KHZ can be simple to 10KHz frequency measurement by digital tube display!)

菜单编程操作的源代码，有助于对菜单的理解。。(Menu programming operation of the source code, contribute to the understanding of the menu. .)
