Customizable Transceiver Design of a Visible Light Communication System

Visible Light Communication (VLC) is an optical wireless communication technology that can be used for data communication over optical wireless link. In this paper, a complete state-of-the-art Visible Light Communication (VLC) transceiver prototype has been physically designed. The developed VLC transceiver prototype can serve the purpose of both illumination and data communication simultaneously. The novelty of the design lies in the fact that it uses STM32F4Discovery board which is customizable over the Universal Synchronous/Asynchronous Receiver/Transmitter (USART) TX and RX protocols. The work covers complete hardware design of the transceiver including LED driving circuit, and full configuration of the STM32F4Discovery board. Furthermore, the proposed VLC design can also be used for audio communication.
