直流电机的闭环控制 实验采用89C51，编译环境 Keil C 51-Closed-loop DC motor control experiment using 89C51, compiler environment Keil C 51

1.将P1.0～P1.3接开关，将P1.4～P1.7接发光二极管。依据P1.0～P1.3开关状态控制P1.4~P1.7发光二极管点亮。 2.将P1.0～P1.7全部接发光二极管，开始P1.0、P1.5点亮，左循环50次后P1.1、P1.4点亮；右循环30次，循环往复。-1. P1.0- P1.3 will then switch to P1.4- P1.7 access LEDs. P1.0- P1.3 based on state control switch P1.4- P1.7 LED lights. 2. P1.0- P1.7 will take all LEDs started Schematic, P1.5 lit, the left circle after 50 P1.1 and P1.4 lit; Turn right circle 30 times repeated.
