The J1922 Protocol Stack provides a simple application program interface (API) for sending and receiving SAE J1922 messages over a SAE J1708 network. The J1922 protocol stack abstracts away the technical details and complexity associated with encoding and decoding of J1922 messages. This increases the simplicity of your application software, improves your reliability, and shortens your product's time to market.

The J1922 protocol stack was designed by Simma Software and has been used in numerous automotive embedded systems. Also, it is validated to withstand 100% bus utilization on multiple networks simultaneously.
