Guest lemmyc Posted November 8, 2009 Report Share Posted November 8, 2009 Hi all, I'm considering getting a pulse as a cheap way to start developing for Android. Does anyone know if the device might support multitouch if the OS was upgraded to Android 2? Seems to be a lot of confusion about the screen tech on the Pulse. Thanks.

Guest Boony123 Posted November 8, 2009 Report Share Posted November 8, 2009 if the G1 can do it im sure the pulse should be able to also. just a matter of "if" the pulse gets an android update any time soon. Link to comment Share on other sites More sharing options...

It doesnt have anything to do with the Pulse needing an update. The g1 supported this on 1.5 (same version of android as the pulse has). However the code to support multi touch has to be implimented in pulse kernel. To do this we need the kernel source, which should be along in the next week or two.

Guest steviem Posted November 9, 2009 Report Share Posted November 9, 2009 Are we all agreed that the Pulse has a capacitive screen? If it's resistive, multitouch won't work. Link to comment Share on other sites More sharing options...
Guest Paul Posted November 9, 2009 Report Share Posted November 9, 2009 It's definitely capacitive. Therefore theoretically it can do multitouch. P Link to comment Share on other sites More sharing options...
Guest steviem Posted November 9, 2009 Report Share Posted November 9, 2009 Awesome! I was unsure when I read conflicting reviews, but when I tried using the screen at the T-Mobile store, I knew the screen was just about good enough to replace the iPhone.

Guest blaze23 Posted December 19, 2009 Report Share Posted December 19, 2009 any news about multitouch??? im aslo very interested to hear about any progress in getting multiouch on the pulse. its a real shame that huawei didnt impement it like motarola and htc...

Guest iamdarren Posted December 27, 2009 Report Share Posted December 27, 2009 i really want to multi touch functionality, ive get envy of the palm pre and the htc hero with pinch zooming. i hope it can get working soon. Link to comment Share on other sites More sharing options...
Guest AndAddict Posted December 28, 2009 Report Share Posted December 28, 2009 (edited) I'm going to see if I can gather some information on this, hopefully see how its implemented in the cyanogen mod and if I can add it to the pulse kernel. Don't expect much soon, ;) I just got my pulse 2 days ago and I'm still playing around with the custom roms at the moment Any help is much appreciated :) Update: Ok, The driver multi-touch code is here: cyanogen GitHub The drivers appear to be very similar, I will see if I can edit the code in to the pulse kernel. Update 2:Most of the modifications look like they'll be simple drop in and compile, albeit with different filename's Update 3: I copied the driver and input.c from the cyanogen, will compile and test, I think I may be missing something as i don't think it will be that simple Edited December 28, 2009 by AndAddict Link to comment Share on other sites More sharing options...
Guest McSpoon Posted December 29, 2009 Report Share Posted December 29, 2009 I think the Pulse only uses synaptics_i2c_rmi_tm1319.c and cypress_cpt_i2c_ts.c cypress_cpt_i2c_ts.c has an interesting feature, CONFIG_CYPRESS_TOUCHSCREEN_MULTIPOINT, but enabling it doesn't make any noticeable difference as far as I could tell. Even if you successfully merge the cyanogen mod changes into synaptics_i2c_rmi_tm1319.c and it were to work, how would apps be able to use it? The 1.5 API doesn't have multitouch support. How did the HTC Hero do it? Did they use a hack? Link to comment Share on other sites More sharing options...

How did the HTC Hero do it? Did they use a hack? As far as I can tell, its just a modified driver and a modified input.c in cyanogen, that keeps passing it up till its available for the apps to use The input.c and the input.h on the pulse seem to have many methods like that, at one point I found methods for gestures; there completely non-existent on the G1's vanilla kernel :) Link to comment Share on other sites More sharing options...

Guest _Sebastian_ Posted January 10, 2010 Report Share Posted January 10, 2010 Sorry for digging in old Topics ... but i just found a kernel config regarding multitouch for those who want to take a look it's in msm/include/linux/input.h Within the menuconfig you might activate it via: Device Drivers --> Input device support --> touch screen gesture suport (NEW) A picuture of the menuconfig in the attachment Link to comment Share on other sites More sharing options...

Guest _Sebastian_ Posted January 10, 2010 Report Share Posted January 10, 2010 (edited) Does that mean that multitouch is already enabled in the kernel? It's not enabled by default. Maybe somebody give it a try .... Edited January 10, 2010 by _Sebastian_ Link to comment Share on other sites More sharing options...
Guest John Hamelink Posted January 10, 2010 Report Share Posted January 10, 2010 It's not enabled by default. Maybe somebody give it a try .... I would, but I don't have a pulse yet :) I can't wait to get one to be honest! On the topic of modifying the kernel, I've noticed there no videos of people with modded ROMs using the pulse on youtube (there are other handsets running modded pulse roms though), why is that? Is it difficult to make custom ROMs for the pulse, or is it just that nobody's uploaded a video yet? Link to comment Share on other sites More sharing options...
Guest Vince Scott Posted January 12, 2010 Report Share Posted January 12, 2010 I suspect that the only reason google haven't released multitouch in android is purely down to apple holding patents on the "technology" and i bet they aren't too willing to grant google a license to use it.
