本程序使用伟纳300A型实验板，来检测光电旋转编码器的实际每周输出脉冲数。程序中，定时器0用于8位数码管动态扫描定时，时间为1ms(12MHZ晶振)。定时器1工作于模式1，计数器方式，直接测量接在T1脚的脉冲个数。外部中断0，工作于边沿触发方式，接在旋转编码器的Z信号输出上，用于检测编码器完整旋转一周。8位数码管接成动态扫描，接在P0和P2口。左4位，用来显示上一周的实际脉冲数，右4位，用来显示当前周的脉冲数。-Wei satisfied with this program 300A type experiment board, photoelectric rotary encoder to detect the actual number of output pulses per week. Program, the timer 0 for 8 digital tube dynamic scanning time, and time is 1ms (12MHZ crystal). Timer 1 in Mode 1, the counter mode, direct measurement of the pulse connected to the T1 pin number. External Interrupt 0, work on the edge trigger mode, then the Z in the rotary encoder signal output on the encoder used to detect a complete one revolution. 8-bit digital tube connected to a dynamic scan, connected to the P0 and P2 ports. Left 4 to display the actual number of pulses on the week, right four, used to display the current week number of pulses.
