One of the biggest features I'm looking for in either the EVO or Streak (still not sure which I'm going with, gotta wait another month for the Streak to come out) is to have the Android desktop/UI/home screen sent out via HDMI. What I would hope to do is:
- be using the phone
- dock it (with HDMI to display)
- have the display show up on the TV (preferably fitting the aspect ratio and resolution of the display, though not necessarily a requirement)
The thought then would be to use a mouse and keyboard via either Bluetooth or USB (in host mode, obviously), and use the phone on the larger display to function basically as a netbook replacement (web browsing, music/videos, light gaming, light office prod. stuff).
I've seen other people on here asking around if it was possible, which it looks like it ISN'T out of the box...but maybe a developer looking for something to do might pick up on this post. You'd make a lot of people very happy!
I am also very interested in this.
So basically something like this?
http://sven.killig.de/android/N1/2.2/usb_host/
I think a good example would be the functionality that matches the current Touch Pro/Fuze TV-Out functionality... Unlike the HDMI output restrictions that are currently on the Evo device, I am able to use the entire OS (Winmo) to select start, programs, play programs, games (Tony Hawk), etc. The TV acts a full clone to what is on the phone screen itself..
I am looking for similar functionality so I can play a movie, nav, on a HDMI connected slate while the Evo is out of site (examples - vehicle screens, portable screens ). Obviously there would no input commands from the screen attached device, but a bluetooth air mouse could help out with that.
Yeah... would be nice, imagine HID bluetooth devices(wii mote controller) hook the phone to a tv, and play some classic games...
RIGHT ON

Yes, as far as input goes, but it would also need software (or a core OS update?) to push the display out via HDMI, at the same time.
I was really interested in this as a possibility, and certainly took notice of the nexus one with host USB capability. Bear in mind the Nexus One was not pushing the device's display out, it was running an X server, but still a neat idea.
I know that currently only the HTC software can push anything out of the HDMI port, but I expect it is simply a matter of applications knowing to take advantage of it, probably not even drivers.
A quick google of htc evo hdmi API gets you sprints android development site, which says the guide includes info on how your applications can take advantage of the HDMI port. I haven't messed with the android API much yet, but the only issue would be for someone to write an application that can grab the entire display, and then push it out to the port via the API.

Only thing I'd worry about there is that it isn't actually "grabbing" the screen (as in screen captures, polling it for changes, etc) because that could absolutely kill performance. That's why I wonder if it wouldn't require driver access or update, in order to actually "push" the display out the HDMI port (note: I'm not a developer, so I can only do my best to keep up with what potential issues might be. )
Any update on this?
I noticed if you read further down on the USB Host Mode page, there's info on a USB TV driver (TV IN sadly), an X11 driver (not sure which way they mean), and also DisplayLink although I think that is some kind of device you need to buy. If I could X11 remote host my Android that would be PIMP but I doubt I'll get that lucky!
I desperately want to do this myself (TV OUT from Android), whether it be HDMI or USB or whatever. I need to output the OS and apps (for demo purposes).
i was thinking the same, somewhere along the lines of PdaReach for palm devices. but the monitor being an actual TV for entertainment purposes. ...trying to get my extra ten dollar fee to use. so if and when netflix decides to make a platform for android devices we could hence watch movies on our televisions via our phones streaming to the TV

The framebuffer is unprotected on stock Evo's & rooted Evo's alike, so if you just grabbed every frame as it went through the framebuffer and outputted it to the display, it could be done easily on any Evo. That is unless HTC plugged the unprotected framebuffer bug on a new update.
In any case, it wouldn't be that hard, it'd hurt performance a little, but I don't know for sure. An app wouldn't be that hard to make, think a high speed screenshot app, talk to the devs of ShootMe about how they grab from the framebuffer.

That IS Genius!! Is anyone going to do this, or do I need to? (I have no Android programming skills sadly!)
I finally got a working HDMI cable from Sprint. My Amzer cable is bad apparently!
I'm happy now!
But still, ANYONE want to embark on this project??

i hope someone figures this out because i really need HDMI out on slingplayer to work
I wonder if we can just find the piece of code that the stock Youtube & HTC Gallery uses to take advantage of the HDMI and then implement it as a system service? Or at least have HTC tell or post on their website how to implement the code in their app, especially for the slingplayer!
Ill buy someone an HDMI cable if they're willing to work on this lol

That won't work. It's already in the Evo developer docs as posted by the person above me. All it does is take any VideoView object in any app and broadcast it over HDMI unless you specifically tell it not to in the application manifest.
There is no way to run that as a service. As of yet I've tried the following:
Copy frames via CLI from /dev/graphics/fb0 (the main screen framebuffer) to /dev/graphics/fb1 (the HDMI framebuffer) to see if it is possible to work it like that. It isn't.
Symlink the two framebuffers so in theory whatever happens to one, should happen to the other. It doesn't work either. It does do something since it breaks HDMI output, but it doesn't display the screen. This could be because the resolution doesn't match one of the TVs supported resolutions.
I'm still going to try a custom kernel once I get my build environment set up (hopefully tomorrow) with a few changes, but I can't promise anything. Anything more complicated than Java is a little over my head, but I can do a little.
I'll keep you posted.

So i would like to install a 7" LCD monitor in my car that would take the VGA feed from the Atrix in the HD dock to be able to display things like the GPS functions, MP3 player, etc.
With the 7" LCD's on the market that have touch screen capability (through USB) i was wondering if this could be possible. The touchscreens usually require a driver to operate and i am not sure if there is a way to get the driver to work on the atrix where the USb port from the touchscreen would plug into the back of the HD dock.
Your thoughts would be appreciated.
VGA input on your screen won't wor - the atrix uses HDMI and you will need to convert between the two to get a signal out (VGA is analog, HDMI is digital).
Unless someone writes drivers for a USB touchscreen, as well as getting HDMI mirroring to work in the horizontal position (currently the hack only works for normal vertical orientation), then you're pretty much out of luck.
Using the Motorola Atrix as a CarPC brain is something I'm looking for! I have a Lilliput 669GL-70NP/C/T 7" with HDMI video-in, the touchscreen works over USB and it has a Linux driver. Shouldn't be possible to implemente it in Webtop?

As far as I understand, the driver would have to be precompiled for ARM, or the source code to the driver would have to be available, short of reverse-engineering it.

Yes, this concept is trivial, the questions are if it can be done, the amount of work necessary and if someone is willing to do it.
I personally have very few knowledge in Linux, limited to some terminal commands in switches and other devices, which is far distant to compiling something to another processor architecture!
I've been interested in doing this same thing in my car. You know there's an alternative on ebay but theyre expensive sitting at a litter over $700 and I only see them available on ebay. Its basically a double din dock that functions with or without the included docking device. The device is just a tablet that I believe stock is running froyo & it has capable specs, with 64 or 128 gigbabytes max memory, 1ghz, 512mb ram, I think its a nice size too, a little smaller than most tablets. I'll try and find a reference or link on ebay.
& has video inputs, etc.

I'm wanting to do the same thing using an HDMI connection, not sure if I can use the Atrix or have to build a car PC and connect the Atrix to it though
For all those interested
I have posted an offering for someone to see if they can bring this solution together using the Lilliput Linux drivers. If they can get it to work i have offered to pay. If it does indeed work, i will be happy to share with all of you and defray the cost to me, and or provide more $ to the develper that succeeds.

Would it be possible to use the current webtop hacks to change the webtop to ubuntu and get a touchscreen to work with it? Just brainstorming. Dunno if it's even possible or not

it's a sound thought pattern, however that is not the issue.
the touchscreen usb drivers are designed to run on the i386 architecture, where our phone runs on the ARM architecture.
aka our greek phones dont understand english
I'd translate it myself if I had the source code to the i386 driver and some learning material XD
depending on the filesize of the i386 binary, it would be possible to reverse engineer, however extremely time consuming (probably looking at months)
I too would be very interested in this!
The other option I was thinking about was to buy a 7 inch tablet and mount it behind the bezel in the dash.
In the car I am planning to play with, I would keep the stock Bluetooth-enabled head unit, and just sink it back into the dash some more with either a tablet or a touch-screen monitor sitting in between the head unit and the bezel so it looks good.
The good thing about doing it this way is that the stock head unit has steering wheel controls which will remote-control a Bluetooth stereo device, and also means no need for an additional amplifier.
I.E if I pair my Atrix phone to the head unit by bluetooth, I can play music and use the skip prev/next buttons on the steering wheel to control the Atrix.
So ideally I would dock my Atrix in the car and bring it up on the touch-screen monitor, be able to control through the external touch screen too.
Otherwise I would have a tablet permanently mounted in-dash, connected with Bluetooth to the head unit. Once again could control using the steering wheel.
Please forgive my ignorance - I'm a fairly new developer and know very little about hardware.
The subject line of the post pretty much says it all. I'm looking for something inexpensive with an eInk screen that I can use to type on, as regular monitors tire out my eyes after a while. If no software exists, I'd be very happy to contribute to that development, which is part of why I was looking to the Nook (I'm most comfortable in Java).
Does the current model or any previous eInk model have the capacity to connect a physical keyboard? If not, are there any other eReaders that do have this ability? (I know I can get an eInk screen for a netbook, but I don't want to spend that much if I can avoid it.) I saw a few old threads discussing whether or not USB Host was possible, but none seemed to have a conclusive answer one way or another.
Thanks for your help!
I'm not quite sure if the current version has Bluetooth. But since it is android and if it does have Bluetooth. Chances are there would be the possibility of connecting a Bluetooth keyboard.
Another possibility is getting an eeepc network and replacing the screen yourself with a pixelqi screen. That should be easier on your eyes (though probably not so easy on your wallet)

Sorry, Volcanolotus, but the STR does not have bluetooth. One further option for that would be use the usb connector, converting it to usb host, and adding the physical keyboard. It is just a concept, but it may work.

Hm. I thought so too. Fret not! I just thought of a solution. It has wifi right... Use this! https://market.android.com/details?...?t=W251bGwsMSwxLDEsImNvbS52b2xvc3l1a2l2YW4iXQ..
Though its really a clumsy solution but a solution nonetheless
Though i love the nook, would not a kindle, already having a keyboard be a better option?
Now, in regards to using the USB port as a USB host, in regards to cell phones running android, the hardware is there, though software uses have been hit/miss on. ICS (Android 4.0) enables usb host functionality natively in the operating system, this will probably be your best bet for the functionality you want. The downside is that I would expect it to be atleast a year or longer before ICS comes to the nook.
keyboard now working
I asked verygreen to work on this and 24 hours later, voila.

Please read the post before reply. Device is hard bricked. Software solution not applicable. Hardware solution required.
You probably already gave up on this, but I am answering this so other people get at least sortof an answer.
For the display alone you could try to use a display driver board (Just google for "make your own monitor, DIY LCD controller board" Sadly can't post links yet..)
Will be hard as soldering to the connectors of the display is annoying/nearly impossible.
Next would be touch, and there you would also need to find a driver board (designing this yourself is way out of the scope usually) and then calibrate the coordinates. (Probably okay under linux/unix, next to impossible under windows)
Overall cost would probably surpass what you would pay for a cheap, new device which could run a software solution. (which would be more portable and cleaner looking.)
If you are a linux user, you can tether the tablet to your pc, get a vnc server running on it and then stream the feed via ADB over the usb-cable to your tablet. (ADB can connect ports from your tablet to your labtop and vice versa). This means that you dont have to pay anything for an app, and also do custom stuff like just sharing certain parts of the screen to the tablet etc...
Hi,
I have a Z3 Compact with a broken screen. It displays everything all right, but the touch is pretty much dead. Shame, I loved that phone.
Thus I am looking for interesting ways to make it useful again. It runs Android 6.0.1 right now.
I have an OTG connector, so I am still able to use the device with an USB mouse - BT controller is an option as well. My most basic options are:
- emulation-handheld for old consoles like PSX and SNES
- PC Camera (with apps like DroidCam, IP Webcam)
But before that my most basic question would be:
Will I be able to use the mouse after reseting the device to factory settings? Seems like the easiest way to clear all the data.
Also, I know there are unofficial Android ROMs available - is it possible to install and use them without the touchscreen, only with USB mouse?
And now to some wishful thinking...
Are there any Linux roms for Z3C akin to Raspbian for Raspberry Pie? Z3C most likely has enough power to act as a simple desktop PC for internet and youtube, it also has peripherals (was it called MHL?) to connect it to a monitor via HDMI that should be dirt cheap by now (the question is, is it still possible to connect K&M at the same time? Is USB-hub enough?), so... maybe?
Any other ideas are welcome!

Make sure you have one of the magnetic charging cables so you can at least keep the mouse plugged in at all times AND keep the battery charged Keyboard & mouse possible IF you use something like the OLDER Logitech models with the proprietary dongle. The newer "unified" stuff won't work. BT keyboard / mouse too sluggish in my experience. If you are feeling courageous, and especially if you don't need it as a daily driver, a replacement screen is something like 25 dollars USD on eBay - get the one with a frame unless you are experienced in replacing screens - the replacement screen only units are somewhat FRAGILE.

Thanks, Nezlek! [I pozdrawiam współ-Warszawiaka! ]
Fortunately I have the magnetic cable, so no worries there. I wasn't planning on replacing the screen, definitely not that courageous. I loved that phone, but I am just not good with tinkering inside of small electronic devices. That is why I was thinking about ways of using it with other input tools like OTG mouse or BT controler. Right now I am thinking about getting a MHL cable for HDMI output and giving it with a BT gamepad to my friends kids with some games loaded. I have no other ideas, sadly.
Do you happen to know if OTG works right away after full-reseting the devicse? This is my main concern now.
Good Question ......

I assume that OTG would work right after a re-set. Why not? The support is built into the ROM. As for the MHL cable, another good idea, but you could just as easily screen cast, no? But, for 5 U$D, or 18 zł PLN (take your pick) an MHL cable is a "worth it" experiment. And, if you're feeling adventurous

From personal experience, the only real issues with the Z3C are that the LCD panel is held in place by adhesive, so you have to position those templates rather precisely, OR use glue :crying: OR double-sided tape AND, you have to be CAREFUL re-positioning the speaker. Caution and patience is all you need.
