The Driven Design of CAN-FD Bus Controller Based on Cortex-M0

CAN-FD bus protocol has a high effective data rate and is widely used in automobile internal bus. This paper introduces the design of CAN-FD protocol controller driver based on Cortex-M0 processor, analyzes the development process of CAN-FD driver in detail, realizes multi node communication by communicating with other CAN-FD nodes, and uses CAN-FD analyzer and logic analyzer to grasp the CAN-FD frame on the physical bus. Through the actual CAN-FD communication project, this paper completes the design process of the driven, and provides a reference value for the driven design of other CAN-FD devices.
