USB flash drives are a popular, simple and inexpensive method of moving data from one PC to another. Their use in the embedded market has been limited, however, due to the requirement that a system must have USB host capability to communicate with a flash drive.

In the past, this usually meant that the system needed to be a PC. However, the introduction of Microchip's PIC MCU with USB embedded host capability means that embedded systems can now take advantage of this popular portable media. With the ability to store data to a USB flash drive, a PIC MCU-based application now has virtually unlimited data storage.

This application note demonstrates a data logger application that can run on the Explorer 16 Demo Board with the USB PICtail Plus Daughter Board. It implements a file system with a simple, but powerful, set of commands.
