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

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