> I was thinking of a test program that inverts/cycles the screen colour on registering a keypress. Put a photodiode in front of the monitor and use an electrical switch across the controller button contacts. Cheap parts and an oscilloscope will give microsecond resolution for the end-to-end net case. This, essentially, is one of the ways we measure end-to-end touch latency on modern phones. |
