【Abstract】 Aiming at requirement of the auto idle-speed control system,this paper describes a high-precise displacement measure system based on MSP430, which is drived by stepping motor and measures displacement with linear displacement sensor. Design of stepping motor driver and process of displacement measure are mainly introduced.更多还原
