Hardware requirements#

  • Type-C USB cable

  • FRDM-MCXA577 board

  • Personal Computer

Board settings#

I3C one board:

  • Transfer data from MASTER_BOARD to SLAVE_BOARD of I3C interface, I3C0 pins of MASTER_BOARD are connected with I3C0 pins of SLAVE_BOARD

MASTER_BOARD    CONNECTS TO       SLAVE_BOARD
Pin Name        Board Location    Pin Name   Board Location
I3C0_SCL/P0_21  J2-20             P0_21      J2-20
I3C0_SDA/P0_20  J2-18             P0_20      J2-18
GND             J2-14             GND        J2-14

Prepare the Demo#

  1. Connect a USB Type-C cable between the host PC and the MCU-Link USB port on the target board.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Press reset button to begin running the demo.

Running the demo#

The log below shows the output of the hello world demo in the terminal window:

I3C board2board EDMA example -- Master transfer.
Master will send data :
0x 0  0x 1  0x 2  0x 3  0x 4  0x 5  0x 6  0x 7

I3C master do dynamic address assignment to the I3C slaves on bus.
I3C master dynamic address assignment done.

Start to do I3C master transfer in I3C SDR mode.

I3C master wait for slave IBI event to notify the slave transmit size.
I3C master received slave IBI event, data size 1, value 0x20.

I3C master transfer successful in I3C SDR mode.
