AVR单片机的MP3方案，解码芯片为VS1003

电子秒表的设计 1、用系统8253定时器提供的55ms定时单位，设计秒表定时程序。 2、有关系统定时方法： PC机系统中的8253定时器0工作于方式3，外部提供一个时钟作为CLK信号, 频率：f=1.1931816MHz。 定时器0输出方波的频率:fout=1.1931816/65536=18.2Hz。 输出方波的周期Tout=1/18.2=54.945ms。8253A每隔55ms引起一次中断-Electronic stopwatch design one, using the system timer 8253 provides 55ms timing units, design stopwatch timing procedures. 2, the system timing method: PC system timer 0 of 8253 working in the way of 3, to provide an external clock as the CLK signal, the frequency: f = 1.1931816MHz. Timer 0 output square wave frequency: fout = 1.1931816/65536 = 18.2Hz. Cycle square wave output Tout = 1/18.2 = 54.945ms. 8253A every 55ms caused a disruption

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
