This library implements a Local Interconnect Master node emulation. For an explanation of the LIN bus and protocol e.g. see https://en.wikipedia.org/wiki/Local_Interconnect_Network.

Supported functionality:

• blocking and non-blocking operation
• multiple, simultaneous LIN nodes with independent baudrates and protocol
• optional callback functions for slave response frames

For AVR and SAM architectures this library depends on the Task Scheduler library for background operation, which is available via the Arduino IDE library manager or directly from https://github.com/kcl93/Tasks. ESP32 and ESP8266 use the built-in Ticker library.

Supported Boards (with additional LIN hardware):

• all boards using the Atmel ATMega328 controller, e.g. Arduino Uno and Nano
• all boards using the Atmel ATMega2560 controller, e.g. Arduino Mega
• all boards using the Atmel SAM3X8E controller, e.g. Arduino Due
• ESP32 and ESP8266 boards

Notes:

• No device specific tricks are used, so all boards supported by the Task Scheduler (AVR, SAM) or Ticker (ESP32, ESP8266) libraries should work
• The sender state machine relies on reading back its 1-wire echo. If no LIN or K-Line transceiver is used, connect Rx&Tx (only 1 device!)

Have fun!, Georg
