Hi @Sankeerthan123
The example code was developed to be used in one board. In the description.txt provided with the example, the required connections are specified.
The application will initialize two I2C instances, one as a master and the other as a slave. The master initiates a send transfer on the I2C bus. After the transfer is completed, and both master and slave are idle, the RX buffer of the slave is checked against the master TX buffer.
