MEX file for azure rtos/usbx examples

Good Day!

the example "lpcxpresso55s28_usbx_device_hid_mouse" runs fine on LPC55S28-EVK, however there is no included MEX file for this example or other azure_rtos examples.

Was the board setup code for the above project tool generated? If I would like to adapt this example for a custom board, is there a MEX file i could use?

Thank you!

Hi @steve5528

You are right, that's because these examples are typically not configured using the MCUXpresso Config Tools , but instead use manually written SDK-provided functions for the EVK.

The board setup code for lpcxpresso55s28_usbx_device_hid_mouse was not tool-generated using MCUXpresso Config Tools. The board initialization is done using standard SDK calls.

For a custom board, generate your own .mex project with MCUXpresso Config Tools and bring in USBX source files.
