SAE J1939 And NMEA 2000 Protocol Stack Kits For Rapid Development And Prototyping

Posted by Industry News on

NMEA2000 Protocol Stack Kit for device manufacturers needing to rapidly develop or adapt

Warwick Control Technologies (UK) announced the release of their SAE-J1939-based protocol stack kits that also support an NMEA 2000 protocol stack according to IEC 61162-3.

The company's development kit provides the protocol stack in C source-code, an STM32 prototyping board, a reference design CAN Bus driver for STM32 microcontrollers, the X-Analyser tool, and the Leaf Light USB dongle by Kvaser, including documentation and examples, a one-year email support as well as site or project license that requires no additional royalties.

The kit is available for SAE J1939 and NMEA 2000 (IEC 61162-3). The NMEA 2000 kit provides a sample reference design, which passes the NMEA conformance certification.

NMEA 2000 is a CAN-Bus-based higher-layer protocol (HLP) and application profile for maritime electronics, especially for navigation systems. SAE J1939 represents a set of CAN-Bus-based HLPs and profiles for truck and bus industries. Both protocols are closely related, and they come in one C source-code library that incorporates features such as Address Claim, Fast Packet Protocol, BAM, Connection Management Data Transfer, and more.

Also, Warwick Control offers the development of hardware abstraction layers (HAL) other than STM microcontrollers.

SAE J1939 ECU Simulator for PCs And Embedded Solutions

SAE J1939 ECU Simulator for PCs And Embedded Solutions

The jCOM.J1939.USB gateway board is a high-performance, low-latency vehicle network adapter for SAE J1939 applications. It allows any host device with a USB COM port to monitor SAE J1939 data traffic and communicate with the SAE J1939 vehicle network.

The board supports the full SAE J1939 protocol according to J1939/81 Network Management (Address Claiming) and J1939/21 Transport Protocol (TP). It is also supported by an extensive programming interface for Windows and Linux/Ubuntu applications, including full C/C++/C# source code for short time-to-market developments.

With all its features, the jCOM.J1939.USB allows the simulation of an SAE J1939 ECU (Electronic Control Unit) using embedded solutions such as the Raspberry Pi, BeagleBone, Arduino, Teensy, and others but also PCs running Windows or Linux (incl. Ubuntu, Fedora, etc.).

CAN Bus And SAE J1939 Bus Voltage

CAN Bus MediumAccording to ISO-11898 specification, the CAN bus medium must support two logical states: Recessive and dominant. A CAN controller with its TTL output uses an additional line driver (transceiver) to provide the standard CAN Bus level. The dominant level (TTL = 0V) always overrides a recessive level (TTL = 5V), which is, especially [...]
