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.

Followed instructions on here To activate CAN protocol on Raspberry Pi, you need to run:
sudo ip link set can1 up type can bitrate 500000
# /etc/xdg/autostart/InstrumentCluster.desktop

We tested the prototype both on the stand and on the track, as a result all data is displayed correctly, both speed and battery charge
The project is very important for understanding the interaction of sensors with the controller and computer, as well as data transmission via the CAN system, and processing this data for display on the screen
