Transfer data from MASTER_BOARD to SLAVE_BOARD of I2C interface, I2C0 pins of MASTER_BOARD are connected with I2C0 pins of SLAVE_BOARD

MASTER_BOARD        CONNECTS TO         SLAVE_BOARD
Pin Name   Board Location     Pin Name   Board Location
I2C0_SCL       J2-20          I2C0_SCL       J2-20
I2C0_SDA       J2-18          I2C0_SDA       J2-18
GND            J2-14          GND            J2-14

Prepare the Demo

Connect a Type-C USB cable between the PC host and the OpenSDA USB port on the board.
Open a serial terminal on PC for OpenSDA serial device with these settings:
- 9600 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
