Design and Realization of Stepping Motor Drive System Controlled by Single-Chip Microcomputer

In order to meet the needs of operation and management of multiple stepping motors in the current Internet of things environment, this paper designed the software and hardware of the stepping motor drive management system under the control of a single-chip microcomputer based on LabVIEW, which is a graphical programming platform developed by National Instruments Corporation of the United States, and tested and verified the functions of the system. The software part of the system transmitted data between the host computer and the driver terminal based on a service cloud platform called Easy-Control, realizing the network real-time online management operation function. In the hardware design, the existing functions of the STM32F407ZGT6 single-chip microcomputer were combined with the the design of the special driver chip LV8726TA to simplify the circuit design of hardware to increase system stability. The comparison demonstrated that the software and hardware of the system were developed on the LabVIEW platform, which had the advantages of high efficiency, short development cycle, low cost, and convenient function expansion. This work provides a scheme for the design and implementation of similar systems.
