I realize it's not ideal to measure things that way, It would be better to attach the keyboard directly to the microcontroller, but I don't have a microcontroller that can act as a USB host right now, I may end up getting one in order to eliminate the arduino's USB delay and the OS as variables.Īll I know so far is that the arduino on an interrupt is faster than the keyboard, though that could just be USB polling priority. Anyone know some USB probing software that can grab raw USB data from two devices simultaneously? How about something that logs the exact time a key is pressed? I'm now able to use an arduino to snoop a keypress directly, and pass that on to the computer, but the problem is I'm not able to do time correlation between the raw USB input from both devices(at least, not with wireshark and USBPcap). So naturally I broke out my soldering iron and voided my warranty. So after that thread on cherry's keyboard controller, I got curious about my WASD V1's input latency.
