Getting started with USB_HOST_API(flash drive and VCP)

Hi,

I'm new to devloping with a usb host and i need resources to better understand how your API works.

I'm planing that my product will have a usb hub that a usb flash drive for dataloging(in a fat file system(.db/.csv/.bak)) and a vcp (ft232) will be connected to. i've tried your host example code but they don't give much info on how they operate and MCUXpresso SDK API Reference Manual: Introduction don't talk about the host api nor the fatfs.

I'm running my app on a rt1011.

Can you please help?

Thanks

Hi,

Thanks for your reply.
To provide the fastest possible support, I'd highly recommend you refer to the usb_host_msd_fatfs demo in the SDK library.

Have a great day,
