USB interface for custom USB device with MCX N94

Hello,

I am trying to make a USB interface for the NXP MCX N94 microcontroller. The microcontroller will be located on a PCB and it will communicate with a PC host via USB. The microcontroller will send data from sensors on the PCB to the host. 

I figured that my device would fall under the 'custom' USB device category, however, there aren't any examples for this in the SDK repository. I have been looking at the frdmmcxn947_dev_cdc_vcom_bm example, since I thought that this would come closest to my device, but I haven't been able to figure out how to adapt this code for my device.

Any tips on how to start would be greatly appreciated.

Hello @LarsSch 

I also recommend you development based on this demo " frdmmcxn947_dev_cdc_vcom_bm".

USB host (PC side ) request USB device send data. Then MCXN947 send the  sensors data to PC.
