Introduction¶

In this project we have tried to emulate one of the demo program in Psoc starter kit using mbed chip. Wherein we transmit data through wireless communication using zigbee module and the moving the module which we have designed on a single axis which glows LED's which show whatever was transmitted using persistence of vision. We displayed around 14 characters.

The second thing which we have implemented is, we send data through xbee module (transmitter) which is received by receiver xbee module and displayed it on the shiftbrite registers using the same technizue as used for LED's. In this part we could only display at max 4-5 letter or number or special characters.

The last thing which we implemented is we have displayed an Bitmap image using persistence of vision on the shiftbrite register. The bitmap image was processed on matlab and the co-ordinates were included in the source code. We succesfully implemented some images like circle, square etc.
