SAE J1939 Stack

SKU #: EM-5028-10-PL, EM-5028-10-SL
by emotas

The J1939 Stack allows the fast and straight-forward development of J1939 applications.

A comfortable API allows the easy analysis of received data. The SAE J1939 Stack is equipped with a defined driver interface for the easy adaption of different CPUs. A great number of hardware adaptions are available at emotas.

To avoid a waste of resources the SAE J1939 Stack is to a large extend configurable and scalable.

To guarantee a quick start using the J1939 Stack a number of example projects and a user manual are part of the delivery. Also a reference manual that explains the use of functionalities and function parameters is included.

The unique J1939 DeviceDesigner is a tool to manage all PNGs and SPNs in a device easily and to generate code for the J1939 stack.
The import of PGN definitions avoids repetitive and error-prone work.
