Abstract

U okviru rada istražene su mogućnosti i ograničenja za realizaciju ugradbenih računalnih sustava na platformi CubeSat nanosatelita. Proučene su mogućnosti porodice mikrokontrolera STM32F4 te su opisane komunikacijske sabirnice za razmjenu podataka s drugima računalima unutar nanosatelita (UART, I2C, CAN). Razvijen je prilagodljivi programski okvir za razmjenu poruka i podataka između ugradbenog računala za obradu podataka i drugih računalnih jedinica u nanosatelitu. Programski okvir omogućuje jednostavnu implementaciju podsustava za razmjenu poruka uvođenjem sloja apstrakcije prema fizičkim komunikacijskim sučeljima na mikrokontroleru. Implementirana je podrška za komunikacijska sučelja UART, I2C i CAN. Višezadaćnost i prenosivost rješenja postignuti su korištenjem operacijskog sustava FreeRTOS. Razvijeno je programsko okruženje za testiranje okvira za komunikaciju u programskom jeziku Python.

Abstract (english)

In this thesis the possibilities and limitations for embedded system implementation on the CubeSat nanosatellite platform were investigated. The capabilities of the STM32F4 microcontroller family were studied, along with communication interfaces for data exchange with other computers within the nanosatellite (UART, I2C, CAN). A flexible software framework for message and data exchange between the embedded computer for data processing and other computer units in the nanosatellite was developed. The program framework facilitates the implementation of the message exchange subsystem by means of an abstraction layer over the physical communication interfaces on the microcontroller. Support for communication interfaces UART, I2C and CAN was implemented. Multitasking and portability were achieved by using the FreeRTOS operating system. A software environment for communication framework testing was developed in the Python programming language.
