The LIN middleware implements a slave node for the PSoC 4000S, PSoC 4100S, PSoC 4100S Plus, PSoC 4500S, and PSoC 4100S Max devices.

• Full LIN 2.2 Slave Node implementation
• Compliance with ISO 17987 specification
• Full transport layer support
• Automatic baud rate synchronization
• Automatic detection of bus inactivity
• Fully implements a Diagnostic Class I Slave Node
• Supports implementation of Diagnostic Class II and III Slave Node
• Full error detection
• Automatic configuration services

Refer to the API Reference Guide Quick Start Guide section for step-by-step instruction how to enable the LIN Middleware Library.

An event-triggered frame reports incorrect data when such a frame is associated with the unconditional frame where the response error signal is placed. To get the correct data, read an unconditional frame instead an event-triggered frame.
