microcontroller programming with USB port

New MCUs bring power efficiency and simplicity to USB for portable embedded applications.

The ubiquity of USB makes it an extremely attractive interface for applications requiring connectivity to a PC or other host device for configuration, periodic downloading of data, or firmware updates. Often these devices are portable, such as medical or industrial tools which remotely collect data that needs to be uploaded at a later time. As these devices are portable, the final USB implementation must be both cost-effective and power efficient.

One of the main reasons for USB’s success is its unparalleled ease of use. But under the surface, USB is a complicated technology that artfully masks the user from the complexity. As a result, developers new to USB often underestimate the effort involved. Many new terms and procedures are also encountered, and things often do not “just work” the way they should.
