Desenvolvimento de um conversor do protocolo de comunicação USB (Universal Serial Bus) para CAN (Controller Area Network)

Abstract

The CAN protocol is a communication protocol developed in the early 1980s by the German company Robert Bosch GmbH. Its use has experienced significant growth in the market, particularly in the industrial sector and, most notably, in automotive applications, owing to its high robustness and transmission speeds. On the other hand, the USB protocol stems from a collaborative effort by various companies aimed at simplifying the connection of different devices used in computers of that time, and it continues to be extensively utilized today. Therefore, the objective of this work is to develop a bidirectional converter between the CAN (Controller Area Network) and USB (Universal Serial Bus) interfaces, with the goal of facilitating efficient and reliable communication between devices that use these distinct interfaces. The development of this project involved the application of knowledge in electronics, programming, as well as the use of various software tools for schematic design and 3D modeling. At the end of the project, a device capable of data conversion between both protocols was achieved, with speeds of up to 1 Mbps, accurately and reliably. Unfortunately, integration with commercial software was not attained, but its use with terminal programs yielded satisfactory results.
