MicroJ1939

by EmSA

Micro J1939 is a small-footprint, commercial-grade implementation with advanced features. Ideal for situations requiring medium configurability during run-time and great performance on any type of platform.

The base stack contains everything to develop a fully standards compliant J1939 node where all transmitted or received PGNs are eight bytes or less.

Portable. Micro J1939 is written in 100% standard ANSI C code allowing for straightforward porting. For targets without standard support packages, designers familiar with their target processor can easily perform the port themselves. Or, ask us for a quote to add support to your target!

Compact. ROM Specifications: 4K - 14K bytes depending upon processor and options selected.

An Affordable Pricing Structure. Micro J1939 offers a low, one-time fee and no royalties on deployed products and includes all source code with every purchase.

Feature Highlights

The following is a non-exhaustive overview of features in Micro J1939:

  • Network management

  • Address claim

  • NAME

  • Single frame PGN transmit/receive

  • Persistent periodic PGN transmit

  • PGN data update

  • Network and stack status call-back functions

  • Optional add-on: Broadcast address mode (BAM)

  • Optional add-on: CMDT peer-to-peer transport protocol

  • Optional add-on: Fast packet transport protocol for NMEA 2000

What's Included

Full documentation is supplied. All software products include a one-year maintenance and priority support agreement that can be extended anytime.

Currently Available Ports

A range of compiler and microcontroller combinations are available. For unsupported combinations you can either perform the port yourself or we can perform it for you.  Please contact us with your requirements for more information.

BAM (Broadcast Address Mode) Plugin

Source code module to add broadcast address mode transport protocol multi-frame transmit/receive PGNs functionality to the stack.

CDMT (Peer-to-peer Transport Protocol) Plugin

Source code module to add peer-to-peer transport protocol multi-frame transmit/receive PGNs functionality to the stack.

NMEA 2000 (Fast Packet Transport Protocol) Plugin

Source code module to add fast-packet transport protocol multi-frame transmit/receive PGNs to the stack, for NMEA 2000 applications.
