[MCXN236] Example source code for OTG

dear nxp

Could you provide the example source code for OTG on mcxn236 ?

I can't find the example `application code hub` and MCUXpresso.

Thanks,
Bryan

Hello @bryan_hong

Thank you for your question.

The OTG protocol is quite complex and has largely been phased out. Using a pin to detect and switch between host and device is a simpler approach.

Please refer to the pin_detect_hid_mouse demo under SDK for reference.

When running the demo,

Host:

Plug in a mouse to the test board. The board acts as an USB host. The stack switches to host mode and some device attached information is printed out.

Device:

Unplug the mouse with the cable. The board now acts as a USB device mouse. The mouse is detached and the USB switches to the device mode information.

Hope it helps.

Alice
