I want to implement USB Mass storage class with MK60FN1M0VLQ12 controller. I want to configure it in Device Mode. Does it require an external USB Transceiver ?
Kindly provide me sample code if anything is available for it.
Full Speed USB has an internal transceiver but High Speed USB requires an external HS one. See the free uTasker open source project for USB-MSD device to SD card, Flash, SPiIFlash (and composites) at links below, which include also K60 and USB simulation for simplest development and understanding.
