Hello,
I'm still playing with my Klipad HC-913 tablet
(http://linux-sunxi.org/index.php?title=MID-KLIPAD_HC-913) but I'm failing to
use the touchpad.
I'm using the FEX I took from Android which saying ft5x_ts is used.
The module is correctly loaded :
$ lsmod
Module Size Used by
ft5x_ts 40564 0
cdc_ether 5104 0
usbnet 16861 1 cdc_ether
and in dmesg :

and it is associated to /dev/input/mouse0 and /dev/input/event1
But
$ cat /dev/input/event1
doesn't display anything when I touch the screen.
As per my readings, I need to patch the source code.
(https://github.com/linux-sunxi/linux-sunxi/issues/178)
So what I have to do ?
- remove IRQF_TRIGGER_FALLING from ft5x_ts.c line 1765 ?
- what about the "multi-touch" ?
- anything else to do ?
Thanks
Laurent
