Board settings

I2C one board:

  • Transfer data from MASTER_BOARD to SLAVE_BOARD of I2C interface, I2C11 pins of MASTER_BOARD are connected with I2C11 pins of SLAVE_BOARD

EVK-MIMXRT595        CONNECTS TO         EVK-MIMXRT595
Pin  Name   Board Location     Pin Name   Board Location
P4_22 SDA    J28-9              P4_22       J28-9
P4_21 SCL    J28-10             P4_21       J28-10
GND          J28-7              GND         J28-7

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J40) on the 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. Launch the debugger in your IDE to begin running the demo.
