J1850 Source Code

The J1850 Device Driver provides a simple application program interface (API) for sending and receiving SAE J1850-PWM or J1850-VPW messages. It abstracts away the technical details and many complexities associated with message timing and interfacing to the physical layer. This increases the simplicity of your application software, improves your reliability, and shortens your product s time to market.

The J1850 protocol stack was designed by Simma Software and has been used in numerous automotive embedded systems. Also, it has been validated to withstand 100% bus utilization on multiple networks simultaneously.
