STM32 microcontroller and CAN bus based FSAE racing car electrical part design

Abstract

A microcontroller is a kind of chip in integrated circuits, which is a device that integrates multiple components together to accomplish a certain function. Compared with the traditional digital module, the advantages of a microcontroller lie in smaller size, lower power consumption, and higher flexibility. Its performance and functionality of the expansion depend on the design and manufacturing process of integrated circuits, and the wide application of microcontrollers cannot be separated from the support of integrated circuits. With the continuous development of integrated circuits, the application of microcontrollers is also more and more extensive; in automotive electronics, industrial control, and embedded systems have been applied on a large scale. CAN bus is a kind of serial communication protocol used for communication between various electronic components in the vehicle. It is one of the most widely used communication buses in the world, and it has been applied on a large scale in the fields of the automotive industry, aerospace industry, industrial control, safety protection, and so on. Scale application. This paper mainly discusses the application of STM32 microcontrollers and their ability to bus in FSAE racing cars, the functions they can realize, and the enhancement of racing car performance.
