Line-In or ext.mic. - possible in stereo? - MDA III, XDA III, PDA2k, 9090 Software Upgrading

Hello people,
i would like to connect an external mic. to my Blue Angel,
and i allready know about the pin assignment of both connectors (22pin or 2,5mm plug).
My question is:
is the analog to digital converter in the blue angel able to do stereo?
if yes, (where) can i solder a stereo line-in to the curcuit?
btw., i'm very happy i found this (wonderful) forum...
merry X-Mas to all of you!

'Philips UDA1380' chip -> stereo sampling!
on that page:
http://handhelds.org/moin/moin.cgi/BlueAngel
they say that BA uses a 'Philips UDA1380' chip
and they have a link for a datasheet (68 pages, pdf) for that chip:
http://www.nxp.com/acrobat_download/datasheets/UDA1380_4.pdf
'Philips UDA1380' chip is capable of doing stereo sampling,
so a BA could be a stereo recorder!
if anybody knows how this could be done,
please give me a hint ...

some things i found:

... if anybody knows if it would work to solder an line-in to the chip
and use that line in for 44khz/16bit stereo recordings,
please let me know...

Well, I took a look at the hi-res photos of the boards on the wiki here:
http://forum.xda-developers.com/files/naked-blue-insane.jpg
and if you rotate the image around 180 degrees, I think the chip in question will be in the top centre of the image on the right.
From looking at the photo, these pins are already hooked up to something. They might even be connected to the same thing, it's hard to tell from the photo. I've not opened my BA myself as it's under guarantee.

hi fraser,
yes, that one is the chip, and yes, it looks like all pins are soldered to the board, but i'm quite sure that they are not connected to anything,
because there is no 'line-in" anywhere on the board (not even a stereo line signal), and thats the purpose of pin 27&29...
the blue angel mic(s) (internal and external) are quite sure connected to pin 31.
i have 2 problems:
1.
i don't know if it's ok to connect an external line to the chip directly,
or if there have to be some 'signal tweak' before sending it into the chip
2.
i don't know if the 'default' driver is able to 'receive' or use stereo signals
- is there some sort of 'software mixer', like in a regular windows pc?
i really need help from an electronics guru...

$5 for anyone who makes this simple program for me

Hey, I've got a 'ghetto' little in car computer system set up and it's a pain having to tap-tap on a 7 inch onscreen keyboard obviously not made for fingers. A full size keyboard just isn't practical in a car environment, however the Kaiser already has a very nice petite one built in.
If anyone can make me a program to send keystrokes FROM the phone TO the computer via USB or bluetooth (usb preferred) I'll paypal them $5, or whatever they see it worth. Thanks a lot!
Good Luck finding someone to do THAT much in depth programing for $5.
But Hey You could get a Sub Sammich!

It's not that much work... (although I'm not taking on any more projects at the moment).
You just need a RAPI Client/Server App coding that can pass the key strokes back and forth.

I'm confused if by car computer system you mean a legitimate computer in your car. If so, GRemote should do the trick http://forum.xda-developers.com/showthread.php?t=427097
you could also use mymobile. It mirrors the keystrokes to the computer or vice versa. not sure if this is what you need but thought I would throw it out there.
ill do it
and retire to oz on the payout..... all £3.28 @ todays exchange rate
It could be helpful. I plan to install a computer in my Nissan Xterra, ITX board and 7" touchscreen LCD. I have the ITX board and everything is ready to install but it's too much money to buy the touchscreen LCD. So instead I deside to break a laptop a part (Dell LH400 NON touchscreen 12") I plan to have the screen in the front somewhere and the board will be in the back and control the laptop with my tilt (w/USB cable or BT). It will be nice to have this kind of software on my tilt.
mayby it should have shortcut to to find application on the computer, like video, pix, gps software, players and more
Gremote
as haywiremonkey said Gremote works very well for that i use it all most every day, i use it over wifi but it says it works over bt also just never tried it. i found gremote in the touch pro software section of the forum.

Windows Mobile as Camera (DSLR) Remote

Hi all,
I am looking for a piece of software that will let me use my Kaiser as a remote for my Canon EOS 450d / Digital Rebel XSi.
This should be possible, both wired and/or through IR, but I can't seem to find this software anywhere!
I have found a program remote controls pentax cameras over IR:

The program can be found on http://gastaldelli.googlepages.com/
or on http://downloads.ziddu.com/downloadfile/1777010/RCFP.rar.html
(more info here: http://www.pentaxforums.com/forums/pentax-dslr-discussion/33345-windows-mobile-pentax-remote.html)
Also, I have found a program that remote controls Nikon Coolpix cameras from Windows Mobile (wired).
found here: http://www.ruwebit.net/article/81
These programs show exactly what I need! I just cant seem to find it for Canon cameras!
(Other relevant software: http://www.idruna.com/remoteediting.html -> a bit too complicated for my intention though!)
Can anyone help me out with this? Any help would be MUCH appreciated!

Would you mind typing the right way up?
In reaction to your post; using a remote would allow for time-lapse shooting, reduces vibration when shooting, etc.
I take it youre not a photographer?
jor3l, hw do u type upside down?
You do know the remotes only cost like $25, right? Probably why no one's bothered to write any software to replace it. http://www.bhphotovideo.com/c/product/116234-REG/Canon_2467A001_RC_5_Remote_Controller.html

[Q] Nook Color wl1271 unlock?

its a long shot but maybe some here can help or at least refer me to someone who can...
i was wondering if anybody was able to enable the Bluetooth and/or FM capabilities of the Nook Color. as it has the wl1271 which according to TI supprorts BlueTooth and FM Transmitting and receiving . it seems to me that it might be a simple software change to enable both of them.
i tried building the original kernel and inserting the BT firmware scripts i download from TI (Froyo_L27.5.2_Connectivity_1271_Panda-1.0-Linux-x86-Install)
and i still cant get the blutooth to show up :-/
any ideas? is there a possibility that the UART interface is not connected on the NC to the BT and therefore cannot control it? i assumed that this chip has only one Host interface which the wifi uses and therefore there shouldn't be any problems with the other capabilities
This isn't the Q&A section

Apply your question(s) in the proper sub-forum, or it might result in a temporary vacation
Actually i'll leave this open, see where it leads to
Here is a thread about the BT and the FM by pokey9000:

very interesting read...
wow
it is a great post but it got dirty with all bunch of other topics, i think this issue deserves its own thread as it can lead to enabling 2 amazing features for the nook.
so, basically we need to see if the HCI interface pins are connected right to enable this feature...
the minimum requirements according to the document are:
12 BT_EN <--> GPIO on OMAP.
13 HCI_TX <--> UART lines on the OMAP. UART2_TX
15 HCI_RX <--> UART lines on the OMAP. UART2_RX
17 HCI_CTS <--> OMAP UART CTS line. UART2_CTS
19 HCI_RTS <--> OMAP UART RTS line. UART2_RTS
but how can we check that? is it possible that B&N didnt connect this on purpose ?
that would be such a waste, on the other hand they didnt put a Mic support 3.5 headphones jack even that its supported...
Someone needs to open the NC... trace and measure...
as the USB host will not provide any data...
Edit:
I found this link from ti... pre-compiled linux drivers...
you may need a panda board...

The WL127x doesn't work like that. It goes through the UART, so there's no enumeration. The kernel doesn't know if it's working until you run succeed in running an hciattach on the interface.

e-Cigarette Mod with a touch screen and music capabilities - firmware upgradeable

Hey there guys, I'm writing in the off topic section about this e-cigarette I've just got, it's called Joyetech Ocular C and it comes with a color touch screen , music player and photo viewer capabilities , bluetooth conectivity, a pedometer to count your steps and from what I understand, it has around 2Gb of memory , it is firmware upgradeable and I'm wondering if there is more that can be done to it in therms of functionality.
It's true that vapers, the people who smoke e-cigarettes as their called, dont really need any of this functionality in their devices since they mainly use them purely for smoking, it's nice however to have something a little extra to go with it.
I've looked online for custom firmwares or methods to customise your firmware for these type of devices, but i've only found info on old devices that come with small monochrome screens and the most you can do is upload logos on to the device.
My interests are on how you can access the root of the system built into these devices since it must have a processor and a file sistem inside, how to edit some of these files , per example, you have the option to upload around 100 pictures and some songs ( the memory on it is 2GB ) but there's no way of deleting them once uploaded, in case your storage gets full.
Also it would be nice if users could implement or extent more functionality in the device, par example it only suports .jpeg files in the photo viewer , .png &/or .gif to use as a screen saver would be nice, more so even video playback capability .
And before I get laffed at for asking so much out of an electronic cigarette, I think that since it does come from the factory with all these functionalities and hardware, it's a shame they dont use it to it's fullest.
So is there anyone having any clues on how to "get inside" these devices and tuning them up ?
I've included the latest firmware I could find for the device as well as the program they offer for you to upload it onto the device. If anybody could crack it opn and take a look inside and see at least what's in there, that would be a start.

Need help finding a new 10.1 Joying Sofia Digitizer screen

Ok, I have a sofia 3gr atom quad core based Joying JY-UL134N2 digitizer screen thats slowly failing from the bottom up.
Joying support have been unhelpful to the point of rudeness and tried to use the problem to sell me another unit, this will be the last Joying device I ever buy.
All Im looking to do is replace the digitizer panel so I can give it to a friend, as everything else still works. I'd hate to scrap it just for such a simple problem.
Its a standoff 10.1 screen model with soft buttons down the left side.
I took it apart and printed o the ribbon cable was the following :
JR-010-GT9271
2016.10.11 J
0817
010
Unfortunately thats all the identification I can find and it doesnt seem to be enough to search for.
In system info :
touch : gt9xx_i2c 9217_1020 (b3f1341c) (0)
Ive double and triple checked (ad flashed) joying update files correct for the unit, and now its on GTX Rom (correct 1024x600 resolution is set).
The MCU file is correct afaik :
2017-10-25 19:26:31 JY_(_R76)_90_C9_7706_5009_CAN(All)_Newlap_AMP
Ive exhausted all options now and I have to conclude its a faulty digitizer unless someone can spot different, and I am hoping someone can link me a suitable replacement digitizer panel.
GT9271 --- Capacitive Touchscreen Driver (CTD)
Hi, we are having similar problems with a Funrover head unit with a failing digitizer. Only purchased in July for GB£255.
It has developed a dead area at the top of the touch panel which also suffers from ghost touches.
Our Funrover is almost identical to a Joying unit. Perhaps both manufacturers used the same Board Reference Design? Supplied by the System-on-Chip (SOC) developer? In our case, Unisoc / Spreadtrum.
Funrover are equally unhelpful in supplying spare parts. Evasive and messages ignored.
However, that part number GT9271 on your screen flex flat cable is for the 10-point Capacitive Touchscreen Driver for MID - the controller IC made by Goodix®
That touchscreen controller uses a standard i2c serial bus interface with the Intel Sofia host.
See https: / / focuslcds.com/content/GT9271.pdf
Is it possible to replace with another GT9271-driven touchscreen? Of identical dimensions and FFC cable type; there are (at least) two types - with 12-contact and with 6-contact.
