&par Example Description

This example demonstrates dual-board I2C communication using interrupts,
where you can configure one board as the Master and the other as the Slave
by choosing different project tags. The SCL and SDA lines (PD5 and PD9)
require external pull-up resistors for stable I2C bus operation.The received data
is then printed via the UART (printf), allowing easy monitoring and validation
of the I2C data exchange.

&par Hardware Description

   I2C     BOARD1       BOARD2
   SCL      PD5         PD5         (External Pull up resistance)
   SDA      PD9         PD9         (External Pull up resistance)

USART2_TX(PD0)
USART2_RX(PC12)
