Abstract

U radu su opisane arhitektura i funkcionalnosti mikrokontrolera ESP32. Objašnjeno je od kojih se dijelova sastoji ESP32 mikrokontroler. Opisane su mogućnosti povezivanja mikrokontrolera s okolinom i mikrokontrolera unutar ugradbenog sustava. Objašnjene su i karakteristike protokola i sabirnice CAN. Opisana su polja koja sadržavaju CAN poruke, vrste CAN poruka, način arbitraže CAN poruka, utjecaj prioriteta CAN poruka, upravljanje pogreškama i povezivanje čvorova u sabirnicu. U sklopu rada osmišljen je i razvijen robustan, otvoren i jednostavno nadogradiv sustav nadgledanja i vizualizacije temeljen na sabirnici CAN. Opisano je sklopovlje, programska podrška i arhitektura sustava. Razvijeni sustav moguće je okarakterizirati kao maketu automobila.

Abstract (english)

This thesis describes the architecture and functionalities of the ESP32 microcontroller. The parts that make up the ESP32 microcontroller are explained. The possibilities of connecting the microcontroller with its environment and the microcontroller within embedded systems are described. It explains the characteristics of the CAN bus and protocol. Fields contained in CAN messages, types of CAN messages, how to arbitrate CAN messages, the impact of CAN message priorities, error management, and connecting nodes to the bus are described. As part of this masters thesis, a robust, open and easily upgradable monitoring and visualization system based on the CAN bus was designed and developed. The hardware, software and system architecture are described. The developed system can be characterized as a model car.
