This article needs to design the DC motor drive controller to complete the button, main controller, liquid crystal display, motor speed measurement and DC motor control. In the DC motor speed control system, the single-chip microcomputer is the hub for the combined control of all modules. All the modules of the system are connected to the single-chip microcomputer through input and output. The single-chip microcomputer autonomously collects peripheral data, and can realize the DC motor in the controlled part of the peripheral after judgment. Speed ​​control system function. The user uses the keys to operate the forward rotation, reverse rotation, speed regulation and emergency stop start of the DC motor. The DC motor is driven by L298, which is driven by the internal H bridge. Liquid display select LCD1602. Through the system scheme design, system circuit design and system software design, the function of the system is finally verified through simulation, and the design of the DC motor drive controller is realized.

In this paper, it is necessary to design the DC motor drive controller to complete the keys, main controller, liquid crystal display, motor speed measurement and DC motor control. In the DC motor speed control system, the microcontroller is the hub of all module combination control, all module modules of the system are connected to the microcontroller through the output input, the microcontroller independently completes the acquisition of peripheral data, after judgment can be in the peripheral charged part, to realize the DC motor speed control system function. The user uses the keys to operate the forward, reverse, speed control, and emergency stop start of the DC motor. The DC motor drive is selected by the L298 and driven by an internal H-bridge. Liquid display select LCD1602. Through the scheme design, system circuit design and system software design, the function of the system is finally verified by simulation, and the design of DC motor drive controller is realized.

In this paper, we need to complete the design of DC motor drive controller, including key, main controller, LCD display, motor speed measurement and DC motor control. In the DC motor speed control system, the single chip microcomputer is the hub of all module combination control. All modules of the system are connected to the single chip microcomputer through the output and input. The single chip microcomputer independently completes the collection of peripheral data. After judgment, it can realize the function of DC motor speed control system in the peripheral controlled part. The user can use the key to operate the forward rotation, reverse rotation, speed regulation and emergency stop start of the DC motor. L298 is selected for DC motor drive, which is driven by internal H-bridge. Liquid crystal LCD1602 is selected for liquid display. Through the scheme design, circuit design and software design of the system, the function of the system is verified by simulation, and the design of DC motor drive controller is realized.<br>
