In a car, the most important device for the communication and interaction between vehicle and driver is the instrument cluster. It must be sufficiently clear and simple to facilitate the understanding and interpretation of all the displayed information related to the vehicle behavior. This work explains the implementation of an embedded Graphic User Interface (GUI) for an automotive cluster using the Qt graphics libraries installed on an optimized and customized Linux operative system, which runs on a low-cost microcomputer Raspberry Pi. Additionally, the implementation of the Shared Memory for the Inter-Process Communication (IPC) between the Graphic Interface application and the middleware is exposed. In the same way, this work was realized following the V-Model software development methodology, which takes into account the requirements identification, architecture definition, development and testing stages. Thus, the maintenance and updating of this work was simplified into such degree that it can be used as a platform for future projects. Finally, the implementation of a simple middleware that allows testing the embedded Graphic User Interface functionality is shown.Consejo Nacional de Ciencia y Tecnología
