A degree project has been carried out at Motion Control, Västerås. The degree project “Grafisk Skärm för Inbyggda System” have developed a first prototype of an embedded system with a display, a graphical user interface with touchscreen and possibilities to communicate with external units. The work initiated with surveys of critical components. A technical specification for the 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 circuit board was made. The components were mounted by hand. After testing and correction of the construction the project has resulted in a first prototype. The prototype meets a lot of the desired requirements for a completed end product. The prototype can display the graphical user interface with good quality, has a working touchscreen and possibilities to receive external communication. Any processing of the external communication was not implemented. The prototype has a good foundation for further development.
