Hello,
we use evdev-drv version 2.7.3 (yocto) and X-Server 1.14.0
we have connect 2 equal touches over usb at your cpu (i.mx6 cpu)
now we see, that evdev_drv mix the events from both touches.
example:
touch two sends
ABS_X 101
ABS_Y 100
BTN_TOUCH 1
sync
touch one sends
ABS_X 1000
ABS_Y 1000
BTN_TOUCH 1
sync
touch two sends
ABS_X 100
BTN_TOUCH 1
sync
the function input_handle_abs_event filter double event. so ABS_Y is
only sent, if it was change.
XEvent
get not X=100 and Y=1000
and that is wrong.
does newer verison of evdev_drv solve this problem ?
regards
Johann
