Hi Harald,
I checked the the codes of "30 consecutive samples" with our new SHARP LCD
again.
I think the codes of "30 consecutive samples" can be removed from the patch.
But please keep the ".oversampling_shift = 4," in the patch.
The reason is that the new SHARP LCD has a good sensitivity so that there is
no noises when touching.
The noises are appeared when using poor LCD.
Sorry to make you misunderstand.
BR,
Johnny.

Subject: Re: [PATCH] hxd8-touchscreen.patch
Hi Johnny, please make sure to keep [email protected]
always in the Cc (I've attached your patch to this mail for the
reference of other readers of that list).
I've also explicitly Cc'ed the author of the original 2410 touchscreen
driver, Arnaud Patard.
I'm not entirely sure if that patch really belongs into kernel space.
The kernel touchscreen driver has the task of passing on raw touchscreen
X/Y samples to the userspace, where tslib will take care of all the
post-processing.
Can you please explain exactly what you are trying to do in your code?
I can read it, but it is not entirely obvious to me what you're trying
to do. Basically you only want to report a touchscreen press after 30
consecutive samples have indicated that it was pressed?
Is this something specific about the touchscreen that hxd8 uses? Is it
particularly sensitive?
Once I know more about this, we can decide if the same can be achieved
by either a different tslib configuration, or a tslib module.
Thanks.
