Abstract

STM32F30x is a high performance MCU based on Cortex-M4 core launched by ST company. It is mainly for analog peripheral applications and motor control equipment. It has a large number of unique peripherals for analog applications and motor control. Its routine contains various instructions and registers that control powerSTEP01.

  Combining the actual needs and the requirements of the subject, this paper combines the latest electronic communication technology, automatic control technology, automatic sensor detection technology and computer technology, and completes the control terminal system with multiple control functions, high scalability and excellent user experience.

We are compatible with the two user interfaces of the host computer and the touch screen. We have completed the development of the powerSTEP01 for the compatible design of the low speed stepping motor and the high speed DC motor. This is an upgrade to the traditional control platform. We have improved Controlling the speed and improving the feedback processing speed make the control device more convenient and faster.
