"基于单片机的步进电机运动控制系统研发样本"

Based on the development sample of stepper motor motion control system with single chip microcomputer.doc. This study focuses on the research and development of a motion control system for stepper motors using the P89C668 single chip microcomputer, which belongs to the Philips enhanced 8051 series. The design utilizes the single chip microcomputer to control the operation of the stepper motor, enabling functions such as start, stop, forward rotation, reverse rotation, and speed control through key scanning and program control. The development tools used in this design are Protel DXP and uVision2, with the system being controlled using assembly language. The main body of the document begins with a brief description of the background of the project, the development environment, and the required functionalities. It then introduces the system design, including hardware selection and development tools, outlining the various device functions and work processes applied in the graduation project to prepare for system hardware design. The detailed system hardware design is presented with corresponding circuit diagrams and overall system hardware design. The document also provides a simple description of the interface hardware debugging of the enhanced 8051 single-chip microcontroller circuit. Key words: single chip microcomputer, stepper motor, 8051.
