Zajem zaslonske slike iz vgrajenih naprav

Grmek, Rok (author), Bulić, Patricio (mentor)

Cilj diplomske naloge je bil razvoj sistema za zajem zaslonske slike iz obstoječih vgrajenih naprav podjetja Pipistrel. Omenjene naprave omogočajo povezljivost v omrežje CAN, prav tako pa je s primernim vmesnikom možno v omrežje CAN priključiti tudi osebni računalnik. Ciljni sistem torej predvideva aplikacijo za osebni računalnik, s katero lahko uporabnik preko omrežja CAN zahteva zaslonsko sliko iz vgrajene naprave in programski modul za vgrajeno napravo, ki poskrbi za izvedbo omenjene akcije na vgrajeni napravi. Razvoj sistema je potekal po metodologiji RAD, kjer je najprej bil pripravljen prototip, ki obsega le ključno funkcionalnost brez kakršnihkoli optimizacij, za tem pa je bilo dodanih več izboljšav. Te se nanašajo predvsem na pomanjkanje pomnilnika na strani vgrajene naprave in nizko pretočnost omrežja CAN. Končna implementacija je bila preizkušena na dveh različnih vgrajenih napravah.

• Title: Capturing screenshots from embedded devices

Abstract

The goal of the diploma thesis was the development of a system for capturing screenshots from existing Pipistrel embedded devices. These devices offer CAN network connectivity, and with an appropriate interface, a personal computer can also be connected to the CAN network. The target system therefore envisages a personal computer application, where a user can request a screenshot from the embedded device via the CAN network and a software module for the embedded device, which ensures that the said action is performed on the embedded device. The development of the system was carried out according to the RAD methodology, where a prototype with only the key functionality and without any optimizations was prepared first, and then several improvements were added later. These mainly concern the lack of memory on the embedded device side and the low bandwidth of the CAN network. The final implementation was tested on two different embedded devices.
