Telemetry allows to monitor the behavior of a system and it is applied to many different and\npopular fields such as motorsport. In this case, a data-logger collects all the data coming from different\nautomobile sensors providing a very reliable image of the car status and a better vehicle setup. This\npaper is focused on the development of a new data-logging system for motorsport application, which\nmeets several process constraints, such as high throughput and low power consumption that, to the\nbest of the authorsâ?? knowledge, the available devices on the market were not able to satisfy. The new\ndata-logger consists of a fixed and a removable part, which exchanges data through a transceiver\nexploiting the visible light communication (VLC) technology. In this way, every physical contact\nbetween the two parts of the system is avoided. All the communication procedures are managed by a\nmicro-controller mounted on each part of the system. The transceiver consists of the AFBR-1634Z and\nAFBR-2634Z (Broadcom Limited, San Jose, CA, USA) components, the optical fiber transmitter and\nthe receiver, respectively, produced by Broadcom Inc. By keeping the distance short between them,\nthey can assure a real wireless communication, even without using a high throughput technology\nlike optical fiber. The entire system is powered by an inductive coupling system. In order to test\nthe transceiver, it is connected to a micro-controller reaching a data rate of 8 Mbit/s. But even better\nperformance is achieved by upgrading the micro-controller and changing the transmission technique,\nconnecting the transceiver to the serial peripheral interface (SPI) port of the micro-controller: in this\ncase, a data rate of 21 Mbit/s is reached, perfectly suitable with the application requirements and\neven further.
