USB Software Stacks - Multi-layer Communication

usb softwareUSB won the battle for the Serial Bus standard thanks to it being very universal and applicable to almost every use. However, this has a price of pretty complex software layering to support various devices without causing data overflow.

Evatronix has not only developed software drivers for all of its IP cores, but also optimized some of them to fit the most popular configurations. Both USB High Speed and Low Speed IP cores have software stacks available in two versions: regular and 8051-optimized.

For fast implementation of USB functionality in the user's design, we supply most of USB classes upon request.
