Grafisk skärm för inbyggda system
Framtagning av en prototyp
A degree project has been carried out at Motion Control, Västerås. The degreeproject ?Grafisk Skärm för Inbyggda System? have developed a first prototype of anembedded system with a display, a graphical user interface with touchscreen andpossibilities to communicate with external units.The work initiated with surveys of critical components. A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made. The components were mounted by hand.After testing and correction of the construction the project has resulted in a firstprototype. The prototype meets a lot of the desired requirements for a completedend product. The prototype can display the graphical user interface with good quality,has a working touchscreen and possibilities to receive external communication. Anyprocessing of the external communication was not implemented. The prototype has agood foundation for further development.
