Multitouch possible in theory?

[Guest BigBearMDC]

Just for the record, that's what I get when I place both fingers on the screen (the red values are weirdly umping around)

If this is some well known bug will you please not making me liar, because everything I did, i did it for you.

I was thinking about the community, with the exception of big bear.

Okay, that looks interesting. I cannot say for sure though if that has something to do with the controller firmware. Could you maybe upload the apk you used so that I can try it also?

What would also be helpful is a longer snippet from your kmsg output (especially when you manage to resize the pictures) :lol:

First I'll upload the application.

I'll make the cat of kmsg wile I'm resizing the pictures.

But I'm wondering.

If u can get the same thing without the flashed touchcontrolle, then maybe:

1. The firmware I flashed isn't the real MT firmware we need?

2. The firmware that the touchcontroller already has is MT.

Also you can try the MT browser and maps.

Thanks Toti :lol:

Yap I think if it works for me that just means that the firmware wasn't necessary for MT.

My fear is that this only works because I patched the driver. I could easily integrate a pinch and zoom functionality in the driver without the hardware supporting MT, that's the problem =/

Best regards,

BB

[Guest BigBearMDC]

Oh well, exactly this works for me too with the stock touchscreen controller firmware =/

For me it even works better, and that's weird.

[Guest totiadrenalin]

Well I guess that I flash the wrong firmware then?

:/

Ok!

So Is there any chance to fix it BB?

Show us a teaser video :lol:

Well, I'm not sure anymore :lol:

Obviously the firmware you flashed didn't change anything although it is totally different from the firmware that was on the controller before.

I'll have to think a bit about this all, maybe its not necessary to flash the controller. Its weird, but we both saw that we get something from the hardware when we put two fingers on the screen.

Hell it would help so much if we had any I2C logger that we could just clip onto the touchscreen controller and see what it does. It just too difficult to say what's going on if you have to watch an Elephant through a 1mm hole ....

[Guest BigBearMDC]

Show us a teaser video :lol:

Actually I could enable pinch zooming in the kernel, if there's interest in that.

[Guest DanWilson]

Yah please! Do we need to flash the touch controller though?

[Guest totiadrenalin]

Well I think that we all need only that for our pulse!

That's why we need the multitouch at 1st. place.

And if u do this I think that it's about time to put an end of this MT project.

Because who plays "Piano" for example on the Pulse?

[Guest BigBearMDC]

Yah please! Do we need to flash the touch controller though?

Nope, not at all. You'll only have to flash the boot image.

But beware, you will be able to pinch and zoom, but not the usual way.

You'll have to put one finger in the down left corner of the screen. If you then move your second finger up and down you'll be able to zoom in or out.

Yap that's kinda true, although I'd really like to see MT on the Pulse :lol:

Well, I'll patch the driver now for pinch zooming. I'll upload a video once its working.

For me its enough :lol:

Well this is better than nothing.

[Guest BigBearMDC]

You can consider it as pinch zooming, but you only move one finger instead of both.

[Guest totiadrenalin]

You can consider it as pinch zooming, but you only move one finger instead of both.

So the second finger will be locked to 255 and the first finger will take control over the pinch and zoom?

Ham?

And then, I flash my touchscreen controll for nothing.

NICE!

:lol:

Ok Man.

Do it.

I want true multitouch on my pulse two.

But I guess that this is the true.

Sad but true.

I'm just wandering if you get that effect better than i get in the video I show, then maybee I have to restore the old firmware?

Ok!

I'll do it.

[Guest DanWilson]

Make it work with Froyo!

[Guest totiadrenalin]

Make it work with Froyo!

Let the froyo like it is now.

First the camera and the video playback to get work.

Then i guess it'll be very easy to patch the CPU clock speed and pinch and zoom.

[Guest flip360]

Make it work with Froyo!

i second that :lol:

[Guest DanWilson]

Yeah but if Bobo does this while making the Eclair version, he won't need to do it again later.

[Guest totiadrenalin]

OK!

I guess you'r right here.

Well do it for froyo two then.
