AN5348 Application note Introduction to FDCAN peripherals for STM32 MCUs Introduction The purpose of this document is detailed hereafter: • Give an overview of the controller area network (CAN) with flexible
AN5405 Application note How to use FDCAN bootloader protocol on STM32 MCUs Introduction This application note describes the FDCAN protocol used in the STM32 microcontroller bootloader, providing details on each supported command. This document applies to STM32 products embedding any bootloader ...
Hello@RickNand welcome to the community :), Which revisionSTM32G474E-EVAL1 areyou using? MB1397-G474EMC-B04 or MB1397-G474E-B04? Did you already test theFDCAN_Com_ITexample provided inSTM32CubeG4firmware? Thanks and best regards, Kaouthar To give better visibility on the answered to...
CANFD报文位数=帧起始(1位)+仲裁段(13/32位)+控制段(8位)+数据段(0~512位)+CRC段(28/33位)+ACK段(2位)+帧结束(7位) 从上述公式中可以看出,影响报文位数主要为仲裁段(帧ID长度)和数据段(CRC段受数据段长度影响)。那么我们通过帧类型、帧长度组合出不同情况报文位数: 标准帧,数据0字节: 帧起始(1位...
4 + The directory `driver` contains the STM32H7 platform driver for Libuavcan. 5 + 6 + A dedicated example application may be added later here. 7 + For now, please consider the following open source projects as a reference: 8 + 9 + - https://github.com/PX4/sapog 10 + - https...
前文讲述了CAN的物理层标准,约定了电气特性,以下介绍的协议层则规定了通讯逻辑。 2.2.1 帧的种类 通信是通过以下5种类型的帧进行的。 • 数据帧 • 遥控帧 • 错误帧 • 过载帧 • 帧间隔 在这些帧当中,数据帧和遥控帧由用户设定,其他的帧由CAN的硬件部分完成。

Getting FDCAN to work was remarkably easy: I just used the STM HAL APIs and was basically done. USB was harder. The last time I made a virtual serial port for the STM32, the mjmech gimbal board, I used the STM provided CDC libraries. However, those are released only under a rather...
For example, they are found in vehicles, farming equipment, industrial environments, etc. How does CAN-BUS work? The fuel level, door sensors, odometer, and many more parts of a car have to communicate with each other somehow, and CAN BUS is what they used to do. These CAN-compatible ...
