Jan. 17, 2012 - PRLog -- SAE J1939 has become the accepted industry standard and the vehicle network technology of choice for off-highway machines in applications such as construction, material handling, and forestry machines. J1939 is a higher-layer protocol based on Controller Area Network (CAN). It provides serial data communications between microprocessor systems (also called Electronic Control Units – ECU) in any kind of heavy-duty vehicles. The messages exchanged between these units can be data such as vehicle road speed, torque control message from the transmission to the engine, oil temperature, and many more.

esd electronics, a leading manufacturer of industrial-strength CAN hardware and software, has developed a all-encompassing set of software tools to support the development, test, and simulation of J1939-based Electronic Control Units (ECU).

The esd J1939 Protocol Stack design allows quick development of applications supporting the SAE J1939 protocol. Written in ANSI-C code, the esd J1939 Stack provides a maximum level of portability, and supports little- and big-endian systems. It is easily adaptable to different target systems through the modification of #include and #define directives.

An SAE J1939 Application Programming Interface (API, Object Code) for Windows is also available. It works in combination with all esd CAN hardware interfaces, and it includes a J1939 Simulation Tool plus J1939/CAN Monitoring software.

The protocol stack includes some very special features to accelerate the implementation task:

•   Sending of PGN data
•   No need to care about BAM or RTS/CTS: done automatically depending on data size and destination. Optionally done by callback, to send even larger amount of data with a minimum of resource usage. Automatic broadcasts: stack can automatically broadcast PGNs in a given interval.
•   Receiving PGN data
•   Done in convenient callback function for easy differentiating between sources and types (complete data, data chunk, interruption etc.) Filtering by PG Number and/or source address possible. Splitting to extra callback for Diagnostic Messages possible.
•   Network Management
•   Automatic handling of address claiming procedures. All four address configuration types possible. (Non Configurable, Service Configurable, Command Configurable and Self Configurable)
•   Multiple Devices
•   Even multiple devices in a single software instance are possible. Activated simply by changing a value in a #define. Interface remains unchanged except for an additional deviceNumber parameter in every function.
•   Configuration
•   Resource specific features controllable by defines:
Max number of possible simultaneously transport protocol transfers (Separated by incoming and outgoing).
Max number of queued BAMs. (BAM queue can even be set to consider message's priority when full)
Max number of automatic broadcasts.
Filter functions are excluded from build when defined to be unused.
•   Portability
•   ANSI C.
Tested under little- and big endian systems.
Simply adaptable to new systems usually just by adding some #includes and #defines. (Examples exist)
