【Abstract】 One closed loop control system using micro-controllers chips such as PIC16F873/876 was introduced and attributes of PIC and PWM Motor Driver were described.The circuit design of the system and corresponding software design were also demonstrated,including control principles.Since PIC16F can be rewritable,it’s convenient to adjust commands to establish PIC controlling.更多还原
