Fine, but have you measured what the CPU cost of that is? > I tried something (very fast, not polished) in Python but i feel the > program lags reading the accels. Does Python's read have any internal buffering (by default)? In Guile (which does) that was the cause of the lag that I saw; and when I added a call to set the buffer size to just sizeof(struct input_event), the lag disappeared.
