====================

Overview
--------

The lin_master sample project shows that LIN sends/receives data at master mode.

Board Setting

Requires a LIN transceiver and USB_LIN debugger
Please refer to  :ref:`Pin Description <board_resource>`  for specific board.
connect LIN transceiver mcu signal to LIN's TX and RX on board, connect LIN transceiver LIN signal to USB_LIN debugger.

Running the example
-------------------

Configure usb_lin debugger:
- Configure com and baudrate, then click `Set to Debugger` option

- Running the example, check the result in debugger window

When the example runs successfully, the log would be seen on the terminal like:

.. code-block:: console
