l298n控制步进电机两相八拍测试程序，加加加几(l298n controlled stepper motor test program)

说明：  非编码键盘是利用MCS—51单片机内部的定时/计数器、中断系统、以及外围的按键和LED数码管显示等部件，设计一个单片机非编码矩阵键盘。并能通过按键实现显示0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F。(The keyboard is used non-coding MCS-51 microcontroller internal timer/counter, interrupt system and the external buttons and LED digital display and other components, to design a single chip non-coding matrix keyboard. And pass the key to achieve display 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F.)
