Protocol Stacks

Protocol Stack

The J1939 protocol stack offers the complete functionality for integration of the SAE J1939 standard into your devices. Versatile configuration options facilitate individual customization to a target product. Example codes facilitate the startup phase, enabling the user to focus on the implementation of their own application. The open CAN driver (CANpie) provides the flexibility to use any CAN controller available on the market.

The bridge function to the CANopen Slave protocol stack facilitates realization of devices with multi protocol capability. In addition, less development time is needed for the implementation of parameters as these are addressed by all protocols in the same way.
