======For User======

For those who want a simple installation package
Can use the following update-package made by mali100, thanks to mali100
mali100 made an update-zip to install multitouch through CWM
[NST][CWR][RC2] Clockworkmod based Recovery



For thise users want to install manually
Can achieve Multi-touch by 2 Steps:

| Replacing Kernel:
| -make sure you haven't changed it before, otherwise u have to combine the changes and compile a new one
| -remember, a backup is a MUST
| for firmware 1.1 users
| Use Noogie or other methods, change the uImage with the attached one ( or the combined kernel mentioned below )
| arkusuma teaches us how to change uImage using ADB here
| *Thanks to arkusuma!
|
| Adding Permission node:
| in "/etc/permissions/required_hardware.xml", add
|

<feature name="android.hardware.touchscreen" />
<feature name="android.hardware.touchscreen.multitouch" />

|
| Reboot



For those users who also want to achieve USB host
Can find the combined kernel here: ( Thanks mali100! )

Known Issue:
Sometimes the nook would act like un-responsive when it is in screensaver.
To solve it, try to drag the screen with two fingers.
The reason for this is, a cache is added between hardware input and linux subsystem, if the driver missed one of the "finger up" event before, it would result it leaving a phantom finger touching in your next touch. The screen cannot unlock by 2 fingers. But when you drag the screen with 2 fingers. It will clear all the cache, so as to erase the phantom touching.

======For Developer======

It is done by editing the kernel + adding permission node

*Thanks to arkusuma, who improved the code, added a cache for touching data, which prevents the pervious "un-stable" situation from happening

Kernel: just replace zforce.c, then compile
Two main changes on zforce,
first one is process_touch_event ( report touch information ),
second one is zforce_probe, this one just added a few input_set_abs_params ( register for device capability )

Permission node: in "/etc/permissions/required_hardware.xml", add

<feature name="android.hardware.touchscreen" />
<feature name="android.hardware.touchscreen.multitouch" />

Thanks to arkusuma for improving the code again !

Why not work multi touch zoom in Opera mini?

Yes, you're right. Thank you.
PS: in UC Browser works too

Congrats on getting multitouch working!

wheilitjohnny,

Congrats on your feat! Maybe you should do a tutorial on how to install those files, for those poor lame souls like myself who can do simple things like run installer and such, even run a rooter, but need help on anything else.

Thank you for your support, I also wish to make a 1-click-install later.

But since the multi-touch is still not very smooth when the fingers are not moving, I want to package the things when I have a better release!

Wish that day comes earlier ^ ^

Could anyone say if kernel for 1.1 will work on 1.1.2? Then could someone compile one if it does not?

Hi, I've made some adjustment of wheilitjohnny's source. It seems to be working properly now, even when there's no finger movement. Changes can be viewed at github:

github.com/arkusuma/nook-touch-multitouch

I'm attaching the resulting uImage for those interested.

Cool ! Thanks arkusuma

You added a cache !


Seems that it is perfect now...

I wanna also improve the noRefresh app, make it being enabled when we are dragging......
But seems difficult
