Použití knihovny LibUSB v prostředí WIN32 pro komunikaci s mikropočítačem přes USB rozhraní.

Abstract

This master thesis researches the possibility of communication between personal computer and microcontroller Atmel AVR equipped with USB interface under the Microsoft Windows operating system with LibUSB library application. In the theoretical part it is described properties and specification of USB bus, which knowledge is premise for understanding of communication trough this bus. Further this part deals with the basic properties of microcontrollers Atmel AVR description and the possibilities of LibUSB libraries. The practical part contains description of process while software equipment developing both for microcontroller and host PC with Microsoft Windows operating system, which is microcontroller connected to. In the conclusion reliability of data transfer between computer and microcontroller was tested and maximum transfer speed was measured.
