Abstract

Koristeći razvojno okruženje Keil uVision, napravljen je program koji inicijalizira brojače vremena, ulaze i izlaze razvojnog sustava te šalje jedan character podatak serijskom vezom. Taj program je prenesen pomoću ST-LINK/V2 do razvojnog sustava STM32F4-Discovery. Razvojni sustav je žičano spojen na USART most koji je spojen na računalo. Time se razvojni sustav spaja na terminal.
Modifikacijom početnog programa napravljen je program koji prima vrijednost napona na potenciometru kao digitalnu vrijednost i šalje te podatke na računalo. Taj program je također prenesen na razvojni sustav pomoću ST-LINK/V2. U programskom sustavu MATLAB, napravljena je skripta koja otvara vezu serijsku vezu, prima podatke prenesene USART mostom te ih grafički prikazuje.
Pomoću MATLAB GUIDE-a napravljeno je analogno-digitalno sučelje. U sučelje se implementira prethodno napravljena skripta te nekoliko dodatnih funkcija sučelja. Tako napravljeno sučelje može primati podatke od razvojnog sustava STM32F4-Discovery, obraditi ih te ih grafički prikazati u realnom vremenu.

Abstract (english)

Using the development environment Keil uVision, a program was made that initializes timers, inputs and outputs of the development systems as well as sends one character data via a serial line. This program is downloaded using the ST-LINK/V2 to the development system STM32F4-Discovery. The development system is connected with wire to the USART bridge which is connected to the computer. This development system is connected to the terminal.
By modifying initial program a new program is made that receives the voltage value of a potentiometer as digital value and sends the information to a computer. That program is also transferred to a development system using the ST-LINK/V2. In programming system MATLAB, a script is made that opens a serial connection, receives data transmitted through the USART bridge and displays them graphically.
With the help of MATLAB GUIDE the analog-to-digital interface is made. Previously made script is implemented to the interface and several additional interface functions are made. Interface like that can receive data from the development system STM32F4-Discovery, process it and are graphically display it in real time.
