LIN (LOCAL INTERCONNECT NETWORK) SOLUTIONS

3 LIN SOFTWARE

Table 6. Software Overview

The LIN standard includes the specification of the communication protocol but also the use of

associated tools.

STMicroelectronics supports the development of your LIN application by providing ready-to-

use LIN software. This software only handles the communication protocol part. For a complete

software development tool solution you can contact LIN specialist third party tools manufac-

turers like VCT (http://www.vct.se) or Vector (http://www.vector-informatik.de).

The software supports LIN slave nodes. It consists of 4 files:

– lin.c/h: protocol handler code

– lin_config.c: LIN parameter configuration file

– lin_ai.c: application interface

A fifth additional file is delivered:

– lib.h: library file (macros, types definition)

The software supports the COSMIC C compiler.
