1.1 Introduction It is an embedded and cloud computing based project. The main aim of the project is to controlling the functionality of PC peripherals such as mouse, keyboard and media (volume) wirelessly by using ARM microcontroller based hardware emulator. ARM microprocessors are used in embedded devices as well as portable devices like PDAs and some phones. The software ARM emulators listed on this page allow you to run an emulated ARM device on your main computer system, be it Windows, Linux or some other operating system. This allows you to develop and test software using your desktop, and only move the software to a real device when it is more complete.
Cloud computing provides computation, software applications, data access, data management and storage resources without requiring cloud users to know the location and other details of the computing infrastructure.
In this project, the USBMouse interface is used to emulate a mouse over the USB port, where we can choose relative or absolute co-ordinates, and send clicks, button state and the USBKeyboard interface is used to emulate a keyboard over the USB port, where we can type strings and send keycodes, send keys with modifiers (e.g. CTRL + 's'), function keys and also the media control keys.
2. EMBEDDED SYSTEMS
2.1 Introductions to embedded systems An embedded system is a computer system designed for specific control functions within a larger system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today. Embedded systems contain processing cores that are typically either microcontrollers or digital signal processors (DSP). The key characteristic, however, is being dedicated
