Touch uinput : send simulated touch/key events to Kobo ?

[Rom1]

I am trying to inject/simulate touch or key events to a Kobo Touch.

evtest /dev/input/event1 (see Antoine's blog)

On a Kindle a "nextpage" event can be send in a different way
echo "send 124" /proc/keypad (mobileread forum)
On the Kobo touch, there is no keypad.

Uinput (/dev/input/uinput) seems a good way to simulate touch pad actions. However I could only find "C" code to send such events. Nothing from the shell.

Is there a way to send simulated touch pad events ?
Thanks for your help,
Romain
