Topics

J1939 Interface

J1939 is a high-level protocol built on the CAN bus that provides serial data communication between electronic control units (ECUs) in heavy-duty vehicles.

J1939 Parameter Group Format

The application layer deals with parameter groups (PGs) sent and received over the network.

J1939 Network Management

Each device on a J1939 network has a unique address.

J1939 Transport Protocols

J1939传输协议将大于8个数据字节和最多1785字节的PGS分为多个数据包。

J1939 Channel Workflow

Diagram to transmit and receive J1939 parameter groups.

MathWorks Virtual Channels
