The main goal of this project is to design and develop a short range intelligent digital radio wireless hub. And this hub must be able communicate between adjacent buildings on the campus using digital transmitter and receiver modules(Easy-Radio style). It also must have some interfacing capability like four LEDs for output and four digital inputs, a local USB interface and also mesh interconnection capability. For example,messages could be passed from hub to hub to provide bi-directional communication between them.
Key areas of this project are as follows:
Design and implement a small system containing an ER400TRS, MM232R and a Microcontroller.
Implement bi-directional communication of ASCII characters between two hubs.
Implement bi-directional communication between more than two hubs arranged in a straight line of maximum error free communication distances.
