Where buses and safety logic become something a human can read at a glance.
Most vehicle software is invisible until it reaches the cluster or cockpit display. This experiment binds real bench traffic to a polished HMI so demos feel like a product, not a debug screen.
We develop against Virtual Bus first for sales and design reviews, then switch the same signal mapping to live CAN-FD traffic without rewriting the UI layer.
Technical Overview
Hardware: STM32H735G-DK cluster board with GPU-accelerated display, S32K144 secondary touchscreen, CAN-FD interface, optional scope for display latency.
Cluster signal sets come from DBC/ARXML conversion; pack/unpack structures from the code generator; scripted Virtual Bus traffic feeds early UI bring-up.
What This Demonstrates
- GPU-accelerated digital instrument cluster
- Live CAN-FD gauges and telltales
- Battery page fed from BMS telemetry
- ADAS alert overlay from perception node
- End-to-end fault warning propagation
- Virtual Bus scripted demo mode
- Secondary touchscreen cockpit HMI
