U ovom radu realizirano je upravljanje digitalnim istosmjernim silaznim pretvaračem (BoosterPack) pomoću grafičkog korisničkog sučelja CCS GUI Composer. Upravljanje silaznim pretvaračem omogućeno je pomoću LAUNCHXL-F28069M razvojne pločice i njezinog mikrokontrolera TMS320F28069M. Za upravljanje se koristila vježba iz Texas Instruments-ove biblioteke, tj. dodatnog programskog paketa controlSUITE. Unutar vježbe za upravljanje u zatvorenoj petlji dodatno su implementirane serijska i paralelna struktra PID regulatora. Objašnjene su izvedbe GUI aplikacije s obzirom na tip aplikacije, odnosno Plug-in i nezavisna aplikacija. Komunikacija realizirane GUI aplikacije izvedena je pomoću JTAG protokola, a dodatno su istražene mogućnosti povezivanja GUI aplikacije pomoću UART protokola ili realizacija grafičkog sučelja (komunikacije) pomoću GUI Composer v2 izvedbe.

Management of digital DC-DC buck converter using a graphical user interface CCS GUI Composer has been realized in this paper. Control is enabled using LAUNCHXL-F28069M development board and its TMS320F28069M microcontroller. An additional software package called controlSUITE (which can be found in Texas Instruments exercise library) was also used. Serial and parallel structures of PID controller have been additionaly implemented for performing a closed-loop control. GUI applications based on the type, such as Plug-in or independent applications have also been explained. Communication of the realized GUI application is executed using the JTAG protocol, and additional possibilities of connecting GUI applications using the UART protocol have been explored, as well as the implementation of graphical user interface using the GUI Composer V2.
