Universal Serial Bus And Peripheral Development
Abstract: For the current statues quo, such as the high cost of USB devices development, the complex establishment of the development platform and the not universal of wireless mouse, this design study USB protocol and computer peripheral equipment development methods based on USB to build a platform and design wireless mouse. The heart of this design is the PDIUSBD12 interface circuit and a wireless transceiver module. The debugging method of the program is circuit debugger. The production of the final design will be a wireless mouse. The mouse has a simple link with computer, a stable operation, a simple structure of the development platform and a low cost.
