DashboardRecord and replay a live diagnostic dashboard
obd2-dash displays car readings, trouble codes and estimated fuel economy in a customizable terminal dashboard. It reads a USB or Bluetooth Low Energy ELM327 adapter, and can record a session for replay or save the raw diagnostic exchange.
Build the Rust app on a computer and plug a compatible adapter into the OBD-II port. Standard readings depend on the car, manufacturer profiles are limited, and the fuel estimates are calculations rather than calibrated measurements; fault clearing is a separate write that asks for confirmation.
