Testing Without Hardware
You can see how flowpilot performs on your device without requiring any extra piece of hardware like panda or connecting to the car. After launching flowpilot, in a separate terminal, launch the dummy publishers script using python scripts/dummy_publishers.py. This will put flowpilot into On road state where you can see your camera stream, lane lines predictions, etc.
There would be a number displayed on the top right corner of the screen. This number is the milliseconds that the device takes to process one single camera frame. This number should technically be lesser than 45 for optimal experience. If this number is above 50, the driving performance will degrade. Please note that, this is a very basic metric, the overall performance will also depend on how your overall system like heat sink, RAM, CPU, GPU, USB speeds, etc.
You can keep flowpilot in onroad state to check for any overheating, etc.
See the performance tuning guide to maximise flowpilot's performance.
