J1939 Protocol Stack

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 done by transport protocol when necessary, callback functions for incoming requests, …
• Automatic handling of address claiming procedures by callback functions: all four address configuration types possible. (“Self Configurable”, “Service Configurable”, etc.)
• Pre-filtering of messages according to PGN and source address
• Parallel communication with several ECUs
• Support of cyclic transmission of PGN data
• Support for multiple physical CAN ports
• Support for multiple logical devices on the same physical CAN port
• Source code license also available
• Easy adaptation to other target systems due to modular structure of the J1939 protocol with well defined abstraction layers
• Written in ANSI-C without endianess and CPU dependency
• Many settings can be adapted to the requirements of the application and the available hardware resources by simple configuration files at compile time

Requirements

• Object license
  • Operating system: Windows, RTX, Linux, QNX or VxWorks
  • esd CAN module, supporting 29-bit CAN-ID (NTCAN-API compatible), e.g. CAN-USB/400, CAN-USB/2, CAN-PCIe/402 (PCI-Express interface), CAN-PCI/402 (PCI interface), CPCI-402 (CPCI interface), CAN-PCIeMini/402 (-FD), CAN-M.2/402-FD ...
• Source code license
  • Embedded CPU with CAN controller and a timer
  • CAN implementation: own, or as additional service by esd (Available for e.g. NXP LPC2292, Fujitsu MB90543, others on request)

Tools

• CANreal monitor and simulation tool
  • Display and recording of CAN message frames with high resolution time stamps
  • Protocol interpreter e.g. for J1939 (optional)
  • Supports message ID filtering
  • Multiple instances of the software on the same or different channels can run at the same time
  • Supports transmission of user defined CAN message frames
  • Supported operating system: Windows
• J1939 DSM (device simulation and monitor) program
  • Simulates a J1939 ECU
  • Multiple instances of the software on the same or 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)

Starter kit

• USB CAN-Controller (esd CAN USB/2) with driver license
• J1939 Stack object license (library) with examples
• CANreal Monitor and Simulation Tool
• J1939 DSM (Device Simulation and Monitor) Program
