This project involves the implementation of an instrument cluster as the second DES (Distributed Embedded Systems) project in the SEA:ME curriculum.
An instrument cluster, also known as a dashboard cluster or gauge cluster, is a critical component of a vehicle’s dashboard. It provides the driver with essential information about the vehicle’s status and performance through various gauges, indicators, and warning lights. Here, we implement an instrument cluster showing real-time speed data on a screen with GUI.

After we have written RaspberryPi OS (Debian Bookwarm, 64bit) to a sd card, we have added lines below to 'config.txt' at the root of the sd card file system. And ejected the sd card and boot up our Raspberry Pi, and we were able to see the display working as expected.
