lpi2c_interrupt_b2b_transfer_slave#
Overview#
The lpi2c_interrupt_b2b_transfer_slave example shows how to use lpi2c driver as slave to do board to board transfer with interrupt:
In this example, one lpi2c instance as slave and another lpi2c instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

MCX-N5XX-EVK
Overview
The lpi2c_interrupt_b2b_transfer_slave example shows how to use lpi2c driver as slave to do board to board transfer with interrupt:
In this example, one lpi2c instance as slave and another lpi2c instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.
