USB flash drive with an embedded host
Microchip PIC USB.
To adapt a USB flash drive for more automated data collection, you typically need a host controller, which at one time limited the device's use to PCs only. Over the last few years more companies, such as Microchip
, have expanded into the embedded market for mobile applications and have included host capabilities into their microcontrollers, enabling their MCUs to connect to and use the storage media.
This presents a host of applications that can take advantage of flash drive storage, such as data logging, which can garner large amounts of data over long periods of time without the need for a PC or laptop. Monitoring everything from weather to environmental hazards can be done with simplistic data loggers outfitted with sensor platforms. The logger can then be retrieved at a later date with the collected data secured in the removable storage that can be accessed from any USB-enabled device.
