This is the documentation for the latest (main) development branch of mcuxpresso sdk. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Hardware requirements

  • Mini/micro USB cable

  • MIMXRT1170-EVKB board

  • Personal Computer

Board settings

Please note that the input voltage to the CMP1_IN1(J25-13) should in the range of 0V to 1.8V.

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.

Running the demo

If CMP1_IN1 (J25-13) connected to the input voltage that in the range of 0.9V to 1.8V then the XBAR interrupt will start. If CMP1_IN1 (J25-13) connected to the input voltage that in the range of 0V to 0.9V then XBAR interrupt will stop. The log below shows the output of the xbar aoi demo in the terminal window:

XBAR and AOI Demo: Start...

Then change CMP analog input.
    - CMP1_IN1 (J25-13) connected to the input voltage that in the range of(0.9V to 1.8V): XBAR interrupt started

XBAR interrupt occurred
