J1587 Source Code

 
The J1587 Protocol Stack provides a simple application program interface (API) for sending and receiving SAE J1587 messages over a SAE J1708 network. The J1587 protocol stack abstracts away the technical details and complexity associated with encoding and decoding of J1587 messages. This increases the simplicity of your application software, improves your reliability, and shortens your product&＃39;s time to market.
 
The J1587 protocol stack was designed by Simma Software and has been used in numerous automotive embedded systems. Also, it has been validated to withstand *** bus utilization on multiple networks simultaneously. If you have questions about J1587, try our J1587 Introduction.

ssJ1587 is high performance SAE J1587 protocol stack written in ANSI C. ssJ1587
adheres to both the SAE J1587 specification and to the software development best
practices guidelines described in MISRA C. The purpose of this protocol stack is assist
developers with accessing J1587 parameters which are embedded in J1708 messages.
ssJ1587 is a modularized design with an emphasis on software readability and
performance. ssJ1587 is easy to understand and can be used on any CPU or DSP with or
without an RTOS.
1.1 Features
? Performs parameter length integrity validation on J1587 parameters.
? Converts J1708 messages into J1587 parameters and presents to application
layer.
? Decodes multi-parameter J1587 messages and presents parameters to
application layer.
? Handles reception of multi-section J1587 messages and presents to application
layer.

1.3 Code and RAM usage
Code size varies based on compiler and compiler settings, but should be approximately
500 bytes. RAM usage varies with the size of the multi-section message buffer.
1.4 Requirements
The processor should have the following:
? A J1708 device driver which conforms to the API outlined in chapter 4 of this
manual.
