For OSU I built a 2-key keyboard (not to improve timing but to avoid destroying my WASD one that was expensive). It's got a 16 mhz mcu in a busy-loop reading two CPU pins.. It should be pretty fast and consistent (but I don't know how much time the actual USB protocol stuff takes, and I suspect that more jitter is introduced in the OS anyway) http://dusted.dk/pages/osukeys/ Yes, I could have used interrupts, but I didn't. |
