Maxim Integrated / Mbed OS FTHR_USBMSD_Demo

USB Mass Storage Device demo with SD card

Dependencies:   USBDevice USBMSD_SD max32630fthr

Fork of FTHR_USBMSD_Demo by Greg Steiert

This example implements a micro SD card reader allowing access to a card inserted into the micro SD connector through the micro USB connector using the standard USB-MSD interface so that it appears just like a USB drive to your system.
