J1939 Protocol Stack

SAE J1939 Support for esd CAN Boards and SoC with CAN Support

Features

  • All SAE J1939 communication mechanisms supported (except bridge function)

  • Full support for the transport protocols ('TP-BAM'/ 'TP-CM') to transmit larger blocks of data

  • Quick software development due to convenient functions: e.g. sending PGN data automatically, callback functions for incoming requests

  • Automatic handling of address claiming procedures by callback functions: all four address configuration types are possible

  • Pre-filtering of messages according to PGN and source address

  • Parallel communication with several ECUs

  • Support of cyclic transmission of PGN data

  • Support of multiple physical CAN ports

  • Support of multiple logical devices on the same physical CAN port

  • Source code license available

System Requirements

Object Licence
  • Operating System:
    - Windows®

    - Linux®
    - other operating systems like QNX® or VxWorks® on request
Source Code Licence
  • CAN implementation:
    own, or as additional service by esd for 16-bit and 32-bit controllers (e.g. NXP LPC2292 or Fujitsu MB90543)


J1939 Starter Kit

  • USB CAN-Controller (e.g. esd CAN-USB/2) with driver license
  • J1939 Stack object license (library) with examples
  • CANreal monitor and simulation tool including J1939 plug in
  • J1939 DSM (Device Simulation and Monitor) program
  • Example source code

Tools

CANreal Monitor and Simulation Tool
(for Windows and esd CAN hardware only)

  • Display and recording of CAN message frames with high resolution time stamps
  • Protocol interpreter e.g. for J1939
  • Supports message ID filtering
  • Multiple instances of the software on the same or on different channels can run at the same time
  • Supports transmission of user defined CAN message frames

J1939 DSM (Device Simulation and Monitor) Program

  • Simulates a J1939 ECU
  • Multiple instances of the software on the same or on different channels can run at the same time
  • Monitors complete PGN traffic on the bus
  • Tx messages can be set up for cyclic transmission or for transmission on request only
  • Transmission of PGN can be triggered manually
  • Manually sending of requests
  • Log shows all user interaction and anomalies in the J1939 protocol parsing
  • Supported operating system: Windows, Linux (as GTK+ application)
