12:52.05szsoftwareis there any difference in /dev/block/loop*, mmcblk*, smd*, whatever in existance of special file or values of major/minor, depending on raphael/diamond/kaiser/polaris/etc.?
12:52.29szsoftwareomg, what a confuse question..
12:54.46szsoftwaree.g. should be /dev/smd* or /dev/block/mmcblk* be equal (also in major/minor) on devices running htc-msm-2.6.27 OR htc-vogue?

19:32.33AstainHellbringdismanteling it huh?
19:33.24cr2the quality is miserable, which i've expected.
19:33.40cr2but it's perfect for hacking. exactly what i need.
19:34.16cr2has usb io, mic in and sound out pins soldered.
19:34.46cr2pin 7 is does not have a cable connected.
19:35.06cr2hmm. need to find the pinout picture.
19:35.19cr2i also got the tvout cable.

21:44.22j0b0howsit going
21:44.48szsoftwarewhen I set "debug=1" in kernel cmdline in default.txt, I have no access to this var in my script,using ${debug}. Can you give me a hint?
21:45.38j0b0does it work for other variables (like 'deebug')
21:45.48j0b0if so, i would say 'debug' gets eaten by the kernel
21:48.14szsoftwarewait..
21:49.00szsoftwareoh, yeah. I think it's a reserved word.
21:49.30szsoftwareHmm, trying dot separated vars in this short notation now..
21:56.59szsoftwareDamn: syntax error: bad substitution
21:58.58szsoftwarej0b0: How do you fill ${imgdevname} with value[s]?
21:59.30j0b0from the cmdline in default.txt
22:01.19szsoftwarej0b0: yes I know. Like this "imgdevname=blah" ?
22:01.43j0b0yes sir
22:03.29szsoftwarej0b0: so unfortunately I just found out, that I can't have access to such a notation:"foo.bar=bla", it gives me bad substitution error in the script. Have to take the long way, grepping /proc/cmdline :-(
22:04.24j0b0variables may not have dots in them
22:07.00szsoftwarej0b0: yes, seems so. But if there is another way to hold this notation, it's ok.
22:08.57j0b0im not sure what youre trying to do
22:13.39szsoftwarej0b0: Ah, dont worry. It works so far. I have some vars, dot separated in cmdline. Like "net.ip=192.168.2.1 net.gw=192.168.2.100 net.service=telnet". You (indirectly) gave me the hint, to use ${foobar}, instead of grepping /proc/cmdline. I found out, that this doesn't work.
22:14.27j0b0use underscores in stead of dots
22:15.04szsoftwarej0b0: this is a logic conclusion ..
22:18.44szsoftwarej0b0: now I know why I took this way. It was the ppp.apn, ppp.username, ppp.password.And I want to have a similar syntax for the vars. So I will have to grep further the /proc/cmdline :-(
22:19.45j0b0..just for the sake of having dots, but its your call of course

22:38.40szsoftwareHey netripper!
22:38.47netripperhi there
22:38.49netripper:)
22:39.08szsoftwareAre you still developing htc-msm-2.6.27
22:39.10szsoftware?
22:39.15netripperno, not at the moment
22:39.30szsoftwarewhen the last time?
22:39.46netripperi had to stop as i needed to put my efforts elsewhere unfortunately
22:39.48netripperemm
22:39.49szsoftwareWhat is the status of the vkb there?
22:39.52netripperlets look at the commit time :)
22:40.08netripperfebruari
22:40.30netripperwhat status specifically?
22:40.33j0b0evening netripper
22:40.39j0b0good to see you
22:40.39szsoftwarehuh, long time ago
22:40.45netripperevening j0b0 :)
22:40.49netripperyes
22:41.03netripperMartijn Stolk, thats me
22:41.08szsoftwarehow is it realized?
22:41.36netripperthe initial vkb was first written by druidu i believe
22:41.44netripperit's hooked in the msm_ts driver
22:42.00szsoftwareok so nothing new
22:42.02j0b0i found that if you combine the data from +0x110 and +0x114 ,
22:42.11j0b0and do soe weird math on it,
22:42.30j0b0you can tell a bit whether you touch with a stylus or a finger
22:42.43netripperwhen the msm_ts driver receives a 'touch' event, it calls the vkb to tell it there's been a touch, and it figures out if it was one of the vkb.. if it was.. the msm_ts driver will ignore the touch and not send it to the linux input system.. if it was outside the vkb, it sends it to the input system
22:43.01netripperj0b0: ah, nice.. i've seen that work in winmo indeed..
22:43.11netrippersometimes i cant scroll with stylus, only with finger
22:43.29netripperi thought they used averaging to see how much of the area is pressed
22:43.41szsoftwarenetripper: thank you
22:43.52netripperthought it worked like, if it's a larger area, it's a finger.. if it's a small area it's the stylus
22:43.54j0b0in winmo, in explorer and settings and things, you can scroll with your finger or multi-select with your nail
22:44.17netripperthere are like 4 or 5 averaging registers
22:44.23j0b0but i havent found any registers or addresses that report size/pressure nicely
22:44.41netripperafaik the touchscreen doesn't support pressure
22:44.53j0b0ok, then its size
22:45.19j0b0it does increase if i push harder with the stylus
22:45.29j0b0but i can see how that would also kinf of increase area
22:46.09netripperhm.. but don't you accidently 'move' your stylus when you press it harder? i've been looking at the regs as well.. and i caught myself moving the stylus a little bit as i applied pressure
22:46.45netripperi think we're currently not using averaging regs in the msm_ts driver
22:47.04j0b0no. only the absolute position
22:47.14netripperyes
22:48.13j0b0so it seems that both 0x110 and 0x114 report position, but 0x114 is offset and scaled and skewed relative to 0x110
22:48.30netripperheh it's funny also.. i was working quite a while on the msm_ts driver to properly detect a "pen up" event.. as the interrupts seem a bit out of sync.. sometimes the last interrupt fires while it was a pen down.. effectively never releasing the stylus
22:48.37j0b0and the amount of offset and scale change as size / area changes
22:49.19netripperso i eventually used a timer to detect a release if there were no interrupts for a while... but then google released a msm_ts driver for the same thing.. and there they had a // TODO: comment that said they needed to add a timer as the last interrupt doesn't always fire
22:49.27netripperwas quite satisfying
22:49.27netripper;)
22:49.34j0b0nice going
22:49.52netripperah ok
22:49.57netripperthats a nice find
22:50.16netripperi think it's also dependent on the configuration we get from winmo
22:50.32netripperthose regs can be configured to report things differently afaik
22:52.00j0b0yes. so for every (x1,y1),(x2,y2) pair, there are a,b,c in x1 = ax2 + by2 +c that are pretty constant across the screen as long as you touch with the same pressure and size, ...etc...
22:52.30j0b0so i solve for those, see what gets bigger/smaller when pushing harder/bigger
22:52.55netrippernice :)
22:53.02netrippermaybe we can translate it to pressure as well

22:58.06netripperim reinstalling my server atm so i dont have time to take a look now
22:58.06netripper:)
22:58.21j0b0you can see how values change more by how tou touch than by where you touch
22:58.38j0b0except near the edges. its a bit unreliable there
22:58.56netripperprobably because the surrounding area is different
22:59.03netripperyou'd need to compensate for that
22:59.30j0b0also when you let got, the last couple of samples are off the charts
22:59.47netripperlol
23:00.05j0b0*let go
23:10.30j0b0so i have 6 values that all vary with how you touch, so i have to normalize and combine them to get a reliable reading
