Input lag testing firmware for PC games

I release the firmware I use when measuring Input lag.

Source code (GitHub)

This firmware is input-lag measurement software for PC games. 
It looks like a normal USB mouse from the PC, and moves the pointer to the left and right automatically.At this time, the LED turns on when the pointer is moving, and turns off the LED when it is not moving. By observing the time at which the movement is drew on the display from the timing when the LED glows up, it is possible to measure the processing time (input-lag) from USB device to display.


See readme_en_how_to_install.txt

I am writing an article about measuring method of input lag.
