[Buildroot] Problem with Touchscreen on ARM

[Buildroot] Problem with Touchscreen on ARM

[Guillaume sétan]

Hello,

I try to use a Touchscreen (multitouch) with my target (Arm Little endian -
Cortex - A9 ).
I tried to use EFL, directfb and fb but I haven't managed to run the
multitouch on my target.

Please can you explain me what packages are needed to use multitouch ?
Or have you ever used a touch screen on a target Arm ?

Regards,

Guillaumme


PS : I see frames on my target (arm ) when I touch my screen with
application mtdev.

 fb is just a framebuffer driver so doesn't have a relation with input events.

 directfb doesn't yet support multitouch AFAIK.

 EFL should support multitouch. But I guess you have to configure it to listen
to the right input device.

 You could try tslib (which converts multitouch to single touch so probably not
really what you want). Qt5 also has support for multitouch.

 What do you mean with 'frames'?

When I try the application mtdev, I see that :

 # ./mtdev-test /dev/input/event1
 supported mt events:
ABS_MT_SLOT
ABS_MT_POSITION_X
ABS_MT_POSITION_Y
ABS_MT_TRACKING_ID

 I don't know, I never used enlightenment, but I expect they have some
documentation, no?
