Middleware CAN protocol implementation

CAN (od engl. Controller Area Network) protokol je serijski protokol temeljen na porukama kojeg karakterizira visoka pouzdanost i robusnost. Prvenstveno je namijenjen primjeni u automobilskoj industriji, ali koristi se i u drugim industrijskim granama. Kako bi se omogućio pregled prometa na CAN sabirnici razvijen je viši protokol koji prihvaća CAN poruke i pohranjuje ih u posebnu strukturu pogodnu za slanje preko USB i Bluetooth komunikacijskih protokola. Protokol je napisan u programskom jeziku C, a podatke prema višim protokolima šalje u obliku JSON objekta. Cjelokupan programski kod napisan je programskim jezikom C i razvijen unutar Keil μVision razvojnog okruženja. Kod je prilagođen za izvršavanje na STM32F407 Discovery razvojnoj pločici.Controller Area Network or CAN is serial and message based communication protocol which main features are high reliability and robustness. Primarily, the protocol was designed for application in the automotive industry but it also has wide application in other industries. The main goal of this project was creating and development of a high-level protocol for forwarding CAN data to higher protocols and user applications. Protocol accepts CAN messages in a special structure and sends structure as JSON object via USB and Bluetooth. This protocol is written in C programming language and developed in Keil μVision development environment. The protocol is created for running on STM32F407 Discovery board
