The Vision IDE from Keil combines project management, makefacilities, source code editing, program debugging, and completesimulation in one powerful environment. The Vision development

platform is easyto

use and it helps you quickly create embedded

programs that work. The Vision editor and debugger are integratedin a single application that provides a seamless embedded project

make?:

While using media files, we can control its different

operations from the distance.

This project makes us realize that there is a whole new

world lives on printed circuit boardsand probably more efficient.

It brings us one more step closer to the future world and
