Hello @Jasper_lin ,

I just consulted the datasheet of FRDM-MCXN947, and I didn't find that P0_24 and P0_25 can be reused for I²C. If you need to use the I²C function of the microcontroller, I recommend that you can download a companion SDK from Select Board | MCUXpresso SDK Builder (nxp.com) . There are some I²C demos for you to refer to. And you can also refer to the user manual, where you can see more specific pin reusing as the SDA and SCL of the I²C.

Hope my answer can help you.

Best Regard

Liu

Hello @Jasper_lin ,

To download SDK, goto https://mcuxpresso.nxp.com/en/welcome, choose the option "Select Development Board".

Then, search for your board model in the search box, build MCUXpresso SDK.

Choose two of the following depending on your situation. Download it.

Open your MCUXpresso IDE, drag and drop your SDK file into the IDE, and you can import SDK examples.

Hope it helps!

Best Regard

Liu
