AN249: Human Interface Device Tutorial - Silicon Labs
Rev. 3/11 Copyright 2011 by Silicon LaboratoriesAN249AN249 Human Interface Device TUTORIAL1. IntroductionThe Human Interface Device (HID) class specification allows designers to create USB-based devices andapplications without the need for custom driver development. Their high levels of on-chip integration and robustUSB interfaces make Silicon Laboratories microcontrollers ideal devices for HID About this DocumentThis application note assumes that the reader has a basic understanding of the USB specification including someknowledge of endpoints, descriptors, and transfer protocols. This document concentrates on highlighting thebenefits of designing with HID and techniques for creating and optimizing HID-based systems that use SiliconLaboratories document includes the following: Discussion of HID Firmware template that can be used as a starting point for HID Device firmware Description of the HID DLL that can be used by host applications to communic
Silicon Laboratories’ USBXpress, which includes a set of custom drivers, firmware routines, and host routines that enable USB communication. HID-class devices simplify USB communication one step further by using a standardized, flexible driver that comes pre-installed with all commonly-used operating systems. Benefits of developing with HID ...
