Hardware requirements

  • Mini/micro USB cable

  • MIMXRT1160-EVK board

  • Personal Computer

Board settings

To make lpi2c example work, connections needed to be as follows:

    LPI2C1 SCL(J26-12)     -->          LPI2C5 SCL(J10-20)
    LPI2C1 SDA(J26-10)     -->          LPI2C5 SDA(J10-18)

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA 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. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
