A modern Qt6 QML-based instrument cluster application designed for PiRacer, running on Raspberry Pi. This project implements a comprehensive dashboard that displays real-time vehicle metrics including speedometer, tachometer, and battery status through Controller Area Network (CAN) protocol and I2C communication.
This instrument cluster application provides a dynamic automotive-grade interface featuring:
- Digital speedometer with real-time speed data from Arduino sensors
- Tachometer displaying motor RPM
- Battery level indicator with status monitoring via I2C
- Modern UI/UX built with Qt6 QML
- CAN protocol integration for reliable vehicle data communication
- Qt6 QML for fluid, hardware-accelerated graphics
- C++ backend for CAN communication and data processing
- Raspberry Pi as the target platform
- Arduino for speed sensor data acquisition
- Cross-compilation setup for Raspberry Pi deployment
- Controller Area Network (CAN) for vehicle data transmission
- I2C protocol for battery data communication
