2020年6月19日 · There are two standards for DB9 pinouts when it comes to CAN bus. This seems to be the industrial version. I've seen it in PLCs and VFDs. This seems to be automotive. The only place I have seen it is in OBD2 to DB9 cables. Where do these standards come from, particularly the automotive one?

2018年6月8日 · CAN is a multi-master broadcast serial bus standard for connecting electronic control units (ECUs). The CAN bus may be used in vehicles to connect engine control unit and transmission, or (on a different bus) to connect the door locks, climate control, seat control, etc.

CAN Bus is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer. Controller Area Network (CAN), is a robust and versatile communication protocol that can be used to send data between an Arduino board and other devices in a networked environment without a host computer.

2024年8月19日 · What is the pinout for this, and how does the DB-9 map to CAN signals? High-Speed-CAN hardware have a 9-pin male D-SUB (DB9) connector for each port. The 9-pin D-SUB connector follows the pinout recommended by CiA DS 102. CAN_H and CAN_L are signals lines that carry the data on the CAN network.

canfd模块是一个can协议引擎，配备了一个非常灵活的邮箱系统，用于发送和接收can帧。该邮箱系统由一组消息缓冲区（mb）组成，这些缓冲区用于存储配置和控制数据、时间戳、消息id和数据。

CAN Bus Pin Out. The pinout for the 9-pin D connector is shown in the table below. Additional connector styles are listed on the CAN Bus Connector Pin out page, or CAN Bus Round Connector Pin out.

CiA 106 recommends connector pin-assignment for CAN-based solutions. In order to achieve interchangeability of devices regarding the CAN interface, it is necessary to use compatible physical connections with a matching plug and socket connector pin-assignment.

2017年5月30日 · Controller Area Network (CAN) is a broadcast, differential serial bus standard, originally developed in the 1980s by Robert Bosch GmbH, for connecting electronic control units (ECUs). CAN was specifically designed to be robust in electromagnetically noisy environments and can utilize a differential balanced line like RS-485.

2020年12月17日 · The current CAN examples default the TX and RX signal to GPIOs 21 and 22 respectively on the ESP32, with CLKOUT and BUS_OFF being left unused). But you are free to change them to the pins of your choosing. Just make sure you pick an Input capable pin for RX and output capable pin for TX.
