[TT] Peripherals possible?

While looking around my phone I came up with a couple of thoughts. First would it be possible to make devices that plugged into the miniusb port on the top of the phone and could it be plug and play? Heck maybe even make the driver if necessary built into flash memory on the new device. It seems like it just takes an kernel update to make something like this possible if it's not already.
The second thing I thought of is if the above isn't possible, why not create an attachable mirror that sits at the right angle to take advantage of the rear camera for video chat. You could project your image onto the mirror and the camera could catch that. The top idea is alot better, the bottom requires alot less knowledge. Either would get us video chat.

Interesting, i like the first idea.

I like the first idea, though for video chat I would rather someone figured out where to pick up the actual modual that goes inside the phone (there's a thread about how they left the mounting brakets in place for the front cam.)
However for other things, like maybe a gamepad+extended battery combo, or an IR blaster to operate my TV

This is the thread you were talking about.

From what I understand about micro usb is that there are five wires/confections. The outside connections are ground and power. The two next to the ground are for data (one + and one -) and the last one next to power is a identification connection. If the wireis connected/has power then its a source device (i.e. computer). If its not, then its a peripheral (portable hard drive, out in our case, our phone). Its been a bit since I read up on that, so it might be vice versa.
Last time I tore the phone apart, I didn't look, but it may be a setting that is hard-wired (literally), or its a switch controlled by software. If it's the latter, then its possible, if its hard wired, then its not.
Adding things to the kernel or loading drivers isn't cut and paste. It takes available source code, which isn't always available, for both the phone and the device you want to use (that works with android), as well as understanding of how to make it work.
That last part I am not well versed on. But we have a couple devs trying to get the vibrant opened up. They are few, and the request list keeps getting larger.

I was just thinking today that it would be great to have a micro-usb device that could house a camera for video chat... I like your mirror idea...I'm prius owner and that's how the dashboard works. The usb is right there...really I think someone should incorporate a device in a mod of the back cover...i don't know anything about code but I could make the case.

Devices require a driver of some kind so the controller knows how to talk to device. For example, if I wanted to hook up my DSLR and control it, I would need a driver ported over and then the SDK for the camera would have to be ported over. An OS like Windows 7 has literally thousands of drivers built in and many other devices require you to install a driver. The only time "plug and play" actually works is either with the OS has the driver already installed or if the device is designed around a generic driver.

Incredible idea! I'm going to make the second idea. I have my own twist on the concept but it shouldn't be to difficult.

I like the first idea but I also had a similar idea and I'd like to see the attached camera come with led's and somehow acct as a flash for both cameras. It could be tiny, if the camera app could be figured out to trigger the flash on all galaxy s models, well at least the vibrant and captivate this could sell.
If a third party app was developed it could be added to any android phone in theory. If that third party app was as good as the galaxy s stock camera app then you'd really be in business.
If I was talking to my brother I'd have tried to convince him to help me develope something. Well I hope one of you talented devs has success with this idea. I'd also like to see success with the guy adding the extra camera internally, I'd be interested in performing the mod if the software end is figured out.

I can take or leave peripheral support, but I'm DYING for USB host mode!

That's the thing, devices that support USB host generally don't use a mini/micro B port. They have specific ports for that. Of course, the USB controller in there may well be able to be a USB host, but we don't know how to enable that from what I have seen. IF the controller can be put into host mode, loads of options like this become possible. It would require kernel mods, but that's not a huge deal. However, as long as we are in USB client mode, the only things we can connect to the port are chargers and computers, as that's all the phone knows how to deal with.

Makes me wonder if you can still take power off of the port and communicate to the device via blue tooth. But I don't think it would come to that.

Oh, it's host mode built in already. One of the major pluses that I weighed in on when buying the phone.
"Both the S5PC110 (smartphone chipset) and S5PV210 (its netbook alternative) are optimized to ensure long battery life for mobile devices, using a 45-nanometer (nm) Low Power fabrication process and low power architectures. With the 1GHz clock speed and 512KB L2 cache, these processors should also manage to provide performance unknown to the ARM world so far.
The two processors have built-in 3D graphics engine and support 1080p full HD video playback and recording at 30 fps. The final nice features of the new chipset include a wide variety of interfaces and peripherals, including HDMI 1.3and USB 2.0 host interface."

Hate to kinda go off topic with the USB Host mode stuff again, but it seems like since the interface is built into the chip, host mode should be enabled in the kernel.
Yes? No?
Has anyone tried to get an OTG cable in there to see what happens?
Just saying.

I've been curious about this since I saw it done (rather impressively) by sonic7406 (YouTube) on the Nexus One. Since then, I hear it's also been hacked on the Droid. From my research, I'm pretty confident this should be possible with the right drivers installed on the Galaxy S series. I've gathered together an (supposedly) OTG "compatible" cable (the Nokia CA-101 for Nokia 6600 Slide/N900/etc), an extra-beefy powered hub, and female-to-female USB-A adapter. I have yet to dive into the kernel to load any special drivers, try mounting drives, etc. I'm still unsure of the "OTG" cable and may still need to manually ground that fifth pin to kick it off. Though, as far as the cable is concerned, that is the only thing that makes it OTG on one end.
Host Mode Background Info: OTG Wiki
Here's a modoco thread that includes most of the relevant links I've seen.
Ideally, I'd like to find a microUSB to USB-B OTG cable that connects directly from my phone to the powered hub, but I couldn't find any. Let me know if anyone knows where we could find these.

It seems like we could create an entire new category of toys to attach to our devices if the micro USB port could be figured out. To me that's ultra exciting!
Let's go a few steps further, Being able to physically attach a printer or hdmi (Yes, I know about AllShare) to the tv could require a simple adapter that plugs into the micro USB port on the handset. We could also have a nice flash that has brackets that mount to the handset for support to get better pics in low lighting (instead of just saying "oh, I've got night mode", bugger that).
The capability to do this has to be written at the kernel level and then we need hardware manufactures willing to make the products. Therein lies the problem, how do we get that to work?

My neighbor is an electronics engineer and I'm a machinist, my friend is a tool and die maker.
My neighbor has an idea to make a device for surface mount soldering using an inert liquid with a boiling point equal to the soldering temp. This would be a cheap alternative to infrared soldering.
Other than that I might be able to come up with a housing.
I wouldn't want to commit myself untill the software works and we've tested the soldering machine.

Do you think will GTab have USB host?

You may not know how useful USB host is. You can use USB stick (up to 32GB), USB keyboard, USB mouse.
If it had USB host, I'd buy it for sure (wifi only).

Sadly NO...
On German Amazon its possible to pre order the device and the datasheed isnt saying something about USB Host
http://ecx.images-amazon.com/images/I/B1gfmv71YkS.pdf
http://www.amazon.de/gp/product/B0041RSF6Y/
This one was my favorite (because of the Phone capability) until you asked this very good question
Maybe they got it rooted in future and then its possible? (depends also on hardware...)
Greetz Tokl

I'd guess that its not going to ever have the capability without hacking. I don't think any device has that at the moment.
I guess what gets hacked depends on what the hackers think is worth doing, and I can see that USB host would be an especailly awesome thing for the Tab so hopefully it will get some interest.
If its a game breaker, you may well be disappoited for a long while tho. This kind of hacking doesn't happen over night.

This is SO true. I remember people trying for years to hack USB host mode in to Nokia's Linux Tablets: the N770 and such. I wonder: Did they ever manage to do it?

Please someone correct me if I'm wrong (as I don't have the device in question) but doesn't the Nokia N8/E7 support just that? I seem to remember a video demonstration of the N8 supporting an USB memory stick.
Also, the Tab will have a dock that has a keyboard, so it's not totally impossible for it to have USB host capabilities.

I don't know about the N8, sadly I just don't have much interest in that part of the mobile space. However, some googling seems to indicate that it is possible (news articles say so) but I don't know if its naitive or needs hacking.
As for the keyboard and stuff, thats a good point. I can't see them using a non-usb standard for that, so it must just be the proprietary connector that makes the difference. In that case, all we should need is a Tab-USB connector, and a few drivers. That would really give the tab some muscle.
In general can mobile devices support the USB min-harddrives ? The ones that power from the port ? If thats possible then the tab will kick serious ass. 250 gigs in your pocket for cheaper than a microSD card.

I'm not really a fan of Nokia's products either, although they USED to make great products they haven't done so in awhile. And I *hate* Symbian. Anyways, at least the N8 DOES have some USB Host capabilities:
"Among the Nokia N8's neater tricks is its support for USB On-The-Go, which basically lets you connect USB peripherals (flash drives, for example) to the phone and have it act as a host..."
http://www.engadget.com/2010/05/30/nokia-n8s-usb-on-the-go-support-demoed-lesser-phones-turned-in/
That was almost perfectly offtopic, sorry for that ^_^
Oh, or not, perhaps! Look what I JUST found:
"USB Standard port adapter
With this kit your Galaxy Tab becomes a standard USB port. With this USB port you can synchronize your digital camera or other devices."
http://www.oled-display.net/more-sa...s-bluetooth-pen-standard-usb-adapter-and-more

Well if they are going to officially make an adapter then maybe we are going to get USB Host... I can't see how you could transfer things off a digicam without the Tab hosting it as a drive.
Well... This looks pretty awesome then.

But they *CAN* cripple the functionality to just mass-storage devices or perhaps just cameras, like Apple did with their USB Camera connection kit, or whatever it was called.
Let's just hope that Samsung doesn't go that route.

Hopefully samsung aren't that stupid Although in theory we should be able to hack it back open anyway, and its a good start at least.

Sorry to resurrect this old thread, but I'm also wondering about usb host (or at least OTG) on the Tab (as I'm considering buying on to port Meego to).
Could someone who has the keyboard doc post the dmesg output once it's been plugged in please?
From some dmesg output I saw elsewhere (but not with the keyboard dock), it appears that the USB chipset is an OTG version, and seeing it act in host mode with the keyboard doc plugged in would be a nice confirmation.

I Would be interested to see the anser for this one.

Yes it is launched (mainly for photographers) i have seen it's price, very cool cheap at £10000 plus something!

It's not the Fools Day yet, so keep your jokes at bay.

OK, I just ordered a keyboard dock and I'll have a look. I'll post a dmesg output and open it to see if the PCB is marked in any way.
According to the pinout (http://forum.xda-developers.com/showthread.php?p=9925838) there seems to be no other way for data to flow apart from USB.
So one of the following must (should) be true:
1. Samsung is reusing the pins for a proprietary protocol -probably reconfiguring the device by pulling up or down other pins.
2. The device is capable of host/OTG mode but it is probably unpowered and it probably needs a pin pull-up/pull-down to enable.
3. The keyboard is using unidentified pins, and the USB pins are used simply for the PC connection and power.
Does anyone know if the keyboard acts as a proper dock? i.e. when you connect it to the pc does it work at the same time as (say) KIES or drive mount?

Just a quick update, the keyboard was just shipped, and I should have it by Tuesday.

USB host
This is a good concept. I have an Archos 70 and a Galaxy tab. Archos has a micro usb port with which I connected my USB host adapter and the key board and mouse works . Flash drive and router dongle says more power required. So I am looking for a powered USB connector for this.
Unfortunately, Galaxy tab has different cable and I dont know if I can find a host cable for this. Any suggestion?

Worth a shot?
After reading this thread:
http://forum.xda-developers.com/showthread.php?p=9925838
I checked the G-Tab pinout :
http://en.wikipedia.org/wiki/PDMI
and tried to ground pin 13 to put the tab in host mode last night... needless to say since I'm typing this on my computer... epic fail. However, I'm curious if anyone else has had any success with this.
I'm not too much of a fan of buying something to destroy... but if I have to disassemble a dock to get the pinout for monitor mode... suck!
Anyone have any advice as to what I jacked up here?

[Q] Any one tried TV-Out Capability on Captivate

Hi,
I am a new user to the forums. Recently I have purchased TV out original samsung 3.5 to RCA cable for TV out capability but I see distorted image on TV. Thought it was a cable problem and went to at&t device support center but they couldn't help me out because they can't test my device at there center. I wonder any one tried it and if so is there any limitation on hardware/software for captivate.
Please help.

Mine works just fine, quality is comparable to an old VHS vcr.
Some cables you have to switch the red audio out with the video to get them to work right.(use right audio for video, and video for right audio)

Thank you Nick for the quick input. I appreciate your concern.

Might want to also try jacking with the cable on the phone end.
The 3.5mm Jack isn't exactly a "Great" output mthod for Video. Try just pulling it up and pushing it down a little. You can fell where the grooves are. Just try to move them around in there to get a better connection.
Thats what worked for me @ least.

I'm slightly miffed as to why Samsung decided no HDMI out, and instead stuck with a crappy 3.5mm headphone out for video.

Works fine for me....can't seem to get the volume any louder though

I also get the same distorted video and a buzzing-hum that drowns out the audio with my 3.5 to RCA/AV cable. I have tried both tv out settings on the phone and swapping the red and yellow ends of the cable. I can, however, use my Play Station 3 to watch, copy and save videos and pictures with the usb cable. It works great and gives awesome audio and video.

Same here.

I just ordered an RCA out cable and am really excited to get it. Even thought it isn't HD it will still be really nice to do.

I was surprised with how good the quality is. I use a cable that came with my Zune dock. It matches correctly to the inputs. My phone looked much better than the Zune did using the same cables.
The audio was great, and the video was as others said VHS quality. Definately watchable. I will say the landscape quality was much better than the portrait quality. On my HDTV I want to say it wasn't full screen, but using the zoom in the TV menu it became full screen, correct proportion.
I agree that Samsung leaving out HDMI support is bad, and disappointing after they told everyone a micro-usb to HDMI cable would fix that, then changed their minds.
This is a problem I won't trouble myself with much longer, I plan on getting an Atrix when they come out.

I just use the usb cable that came with the phone or any other micro usb to usb 2.0 cable. Just write folders on your phone's sd card named PHOTO, MUSIC and VIDEO. Put your photos, music and/or video into the corresponding folders. Plug the phone to the PS3 via usb cable. Turn on usb debugging on the phone. Now look on the PS3 in PHOTO, MUSIC or VIDEO for USB MEDIA STORAGE. There will be all your stuff. You can copy back and forth or just play it on the tv or sound system.

Nexus 7 in-dash car install in Citroën DS5

Hello all,
I've installed a Nexus 7 model 2012 inside my Citroën DS5 (French car). The project is to replace the small original LCD monochrom monitor for car audio (for multimedia only, no GPS).
There was no important mechanical modifications needed, because the original dashboard supports 7 inches first mount original GPS.
The original radio unit FM + CD reader + control buttons are kept. The tab will only be used as external peripheral for multimedia :MP3 and GPS.
In this car I've a duplicate screen on main driver dashboard about FM radio station, so when using FM Radio I can see the selected channel on this screen.
So in fact the main radio unit will 90% be left in "Auxiliary" source and the other 10% "FM radio" source.
Part list :
- Nexus 7 2012 with USBROM
- OTG cable
- USB Hub
- DC to DC 12V to 5V - 5A converter (found on ebay)
- 3 push buttons extracted from an old credit card format IR remote control
- RF cable
- Some wires, soldering material...
Applications :
- JetAudio Music Player (My advice, the best one for in car use)
- Night mode
- Android Weather Clock Widget
- Mappy GPS free (French GPS app), alternatively Tomtom
Installation schematic :
Coming soon. I'm not able to post image links as new user. See attachement.
Notes:
- I've added external GPS antenna because reception was bad using built in antenna. I've just soldered a RF cable on the GPS antenna connector on the mainboard and soldered the small GPS antenna at the end of RF cable,
- The 3 power on and volume buttons have been deported to accessible part of the car. I don't need to use them usually, but in case... I will be able,
- First tries by connecting DC 5V to the USB hub were showing really slow charging. I'v found a thread studying that and it's mainly due to the cable loss. standard USB cable are low section, and as I was going through USB Hub + USB cable + OTG cable... I was measuring less than 4.85V at tablet connector instead of 5.1V at DC converter output. So I've soldered highest section power cables directly after Micro-USB of the tablet and limiting the length to 50cm... Now good success with fast charging.
Tablet Installation :
Coming soon. I'm not able to post image links as new user. See attachement.
I'll try to let this thread as alive as possible.
Thanks for reading, and sorry for my English langage mistakes.

That looks like a very clean install. Nice post.
I have been trying to figure out how to install my Nexus 7 to my car but as it already has a stereo I want to keep i have to find another method.
awesome stuff though !
---------- Post added at 03:15 PM ---------- Previous post was at 03:10 PM ----------
I forgot to ask, is heat a concern for the unit when installed like that and... with the tablet screen on for extended hours is burning an image into the screen not a concern when doing these installs into cars?
I have a S3 which i use as my GPS and do some long road trips. It has now got the point where the map app has burned into the screen faintly. I am wondering if the Nexus 7 would suffer the same result?

Nice, thanks for sharing.
I'm tempt to start something like that in my car, but for now i'm only collecting ideas.
How did you managed to get FM radio on N7?
So far, AFAIK people can get radio on Nexus 7 with bluetooth tethering (unless your N7 has 3G). But then you need a 3G or 4G plan in other phone...
I'm maybe build a customized menu with Zooper Pro, with icons for GPS (tomtom), Radio and USB Audio (jetaudio)..(something fancy like XBMC) and maybe later could add other functions like video or internet browsing.

I've edited main presentation, but I would like to precise that the main stereo unit is kept in this project. Only one simple screen has been removed to be replaced by the tablet. I had the chance in my car to be able to find easy area to put the tablet without needing to remove important unit and replace main stereo.
I'm suprised and not aware about LCD screens that could burn when same image shown during long period. Thought it was for the old screen technolgies. On the other hand, a lot of actual cars are embedding touchscreen tablet similar by default. So I think the technology is now proven. Anyway, I am not using any specific dashboard app for the tablet and so using directly the applications and switching for instance from GPS app to music app.

As edited in main presentation, the main radio unit is kept. So FM radio is left to the main radio unit. I'm using the original buttons below the tablet to control the radio. I'm also still using the original stereo volume buttons including the ones at steering wheel.
For the moment I'm using the standard android desktop and widgets that fits to my utilization, as I only use 2 main application for my tablet ; One for GPS and the second for music.

Few updates since last time on this topic.
I've encountered slow charging issue already encountered by some people. It was discharging faster than charging...
It's linked to the connector inside the tablet between USB PCB board and Mainboard. The solution I've found is to solder directly the USB power to the ribbon cable by removing plastic protection enveloppe on it. Now no issue anymore.
Sometimes I had also issues on GPS reception. I've also soldered a 2m length RF cable to the GPS connectors on the board, and passing it to the dedicated windshield area (UV metallic shield free area). I let a 5cm length internal wire of the RF cable visible on this area, and get better GPS fix statistics.
I need to work on this part to finish a proper installation instead of wire visible on the top of the windshield.
On the other side I've also finished the installation of the rear view camera. I'm using USB video grabber (EASYCAP type) + car camera rear view (easy to find for few dollars on the net).
Presentation of the system available on youtube keywords "Nexus 7 DS5" (sorry I cannot post hyperlinks as new user and sorry again comments are in French):

Want to use phone remotely from pc as security cam. What gadgets do I need?

I just upgraded to an Lg G5 and would like to make use of my M8 instead of sell it.
So I've got one those Y OTG cables but apparently the charging female port is for charging other devices rather than the phone itself. So I'm guessing I need something like this cable but that actually charges the phone too. Any recommendations otherwise, and in addition, can anyone recommend a solar charger that could keep this bad boy powered whilst video recording with motion detection? Otherwise I need that cable if it exists.
And what is the process to connect to a pc and have your phone display pop up on the pc screen? Is "plug-n-play" or more involved? Just need a little direction.
Thanks!
