Hi everyone
One thing that really annoyes me about the xda is that you have to go through a relatively complicated process in order to ascertain who is calling before you decide to answer the phone or reject it. So I've been wondering about an accessory that could change all that.
Since the xda2 has an I/O port (formally usb), wouldn't it be great if there was a way to hook up a small lcd display to a usb cord that could allow users to find out whose calling. It could be extended to become a fully functioning remote control for the xda / 2 including dialing numbers, selecting different mp3's etc.
Many thanks for reading

i agree
hey guys, have you seen this? i think this may answer your questions.

usb devices is devided up into master and slaves
himalaya and the rest (even though there were mixed answers about universal) are slaves and cant init connections to other usb slaves and masters
but the button connector in the himalay also have a old serial port type of connection which can init connection
and then there is the SDIO card interface where only the SD card manufactors set the limit what what you can do (within reason)

Hello everyone - my first post here.
It occured to me that if we could make the XDA2 talk to a hard disk we could fit a big drive in the car and then use the power connector to create communication between the pda and the drive.
Is this possible?
We'd need a new skin for the windows media player with huge simple, finger sized buttons to press to access the different folders and tracks. We would also need a pair of phono outs to go into the car hifi audio input.
Also it would be nice to have a hardware button which would fire everything up so the sequence would be : get in car, clip xda into holder and hit a button. Then you've got 120gb worth of music at your fingertips and if you've got wifi card in there you can take data from your house pc wirelessly and store it on the car's hdd!!! Just awesome.
Any ideas how hard this would be. I would be prepared to pay for development because as a car audio shop owner (www.audiolectrics.co.uk if you are interested!) I reckon we could sell these systems as PDA's like XDA are just phenomenal units - I have had mine now for a week or so and am just bowled over by it!!
the skins in the windows media website are huge enough to use it with your fingers.
or you can try the latest PocketMusic which rocks
Good stuff but how could I add a hard disc drive to it using only the pin outs for usb in the lower charging connector?
Actually I have a sneaky suspicion that the XDA2 won't function as a usb host which is a big problem.
Any ideas? Its' odd because obviously it works 2 way comms when active sync-ing.

The festesting way to adding a HD in the XDA II.

Yes but this is not convenient since you've got to keep taking the xda out of its case.
No, what I need is a wireless hard drive the xda can talk to or a way of making the xda a usb2 host.
Nobody got any ideas?
AHA!!!!
Had a sneaky idea.
What if I buy a backpack and insert a RATOC Compact flash USB host adaptor and plug this into a huuuuuuge USB drive.
Then, make up a cable that connects the xda2 to the BACKPACK which will be hidden out of sight in the car - I presume the XDA talks to the backpack via only the ordinary connectors.
I presume it isn't possible to make a lead up that would connect to a compact flash usb host WITHOUT the backpack - ie that the backpack contains some circuitry?
OK This will work for sure.
I just need someone to photograph the backpack connector where it joins the unit so I can get an idea of the engineering needed.
And one more thing - can I get proper sound output from the main connector of the unit rather than the headphone jack?
it would work if the drivers work ok i suppose
about the audio then all you should need is the connector pin out of xda2 somebody gave them once try search
Seems like there are few individuals actively pursuing this idea. See thread below :

There is also at least one Bluetooth harddisk solution
http://www.expansys.com/product.asp?code=HOPBIT
I recently saw an announcement for a similar product using Wifi instead of Bluetooth. This could be an easier option. Simpply bring the XDAII to your car with the SDIO WiFi card in it and pull the files via WiFi from the Storage Server (err... harddisk)...
OK!
Asus are just about to release their wireless Hard Disk drive! This will have an ftp style interface that will allow password encryption etc so this job looks simple with one of these!
Can anyone help with getting the windows media player sound out on the main connector?

i recently baught a usb 2.0 laptop hard drive case its 2.5 inches small enough to try and convert it to use on the xda2 see link
http://shop.store.yahoo.com/cablesonline/usb2025inlah.html
Yup. Managed to find a reference to this WiFi disc enclosure. Sounds like this will do the job nicely!!!
http://www.asus.com/news/2004/20040311.htm
So Mr Hobbit - we've still got to get XDA2 to talk to the USB though without the backpack for car useage.
This is where the WIFI disk comes in. Chuck it under a seat and feed it juice and hay preso 10000 songs accessible from your XDA control panel.
I love it.
Still need the audio pin outs on the main connector though?
Anyone?
after a quick search in the forum

thanks for that - must admit i don't fully understand what the definitive pin outs are! Could you translate into english for me!! Much appreciated in advance......(!)
I have another Suggestion for the Connection of a Hard Drive to your XDA.
How about connecting up an Ethernet Harddisk such as the one below to a WIFI Access unit or router ( these usually have a 4 port Ethernet Hub built in ) which will be installed permanently in the car ( wired through 12v/240inverter )
http://www.softjam.co.uk/products/index.php?prodref=CU-XIMMNE1040×tmp=1085611877282
This should enable you to access this harddisk over WIFI with the XDA+SD Wifi card?
You`ll then also be able to upload music to your cars Hardisk jukebox whilst its parked on your driveway.
This is what I plan to try anyway ( except I`ll probably add the Backpack so that I can Stream Divx movies from the HardDisk over the Wifi through the XDA2 through the backpage out the VGA Out into my Alpine 7" motorised display ) Fingers Crossed Tomtom will display on the screen also??? we shall see.
I still have to come up with a solution for the sound though as the mini jack is just too arkward.

Hi Guys
The network hard drive looks like a great idea..... combined with one of these http://www.expansys.com/product.asp?code=112376 youve got as much portable storage as you could want.
Hi, i have been reading about this, and i am getting conflicting information, and no real answer.
I have a 2.5" USB hard drive, and was wondering is there any way to plug this into the Magician, and then for the magician to see it as storage. I dont want to use it all the time, just when in the car, and plugged into the Car Stereo.
if its just a case of a lead convertion, then i think it would be simple, but if not.... hmmm.
So if anyone can help i'd be grateful
Thanks

This has been answered several times before, and should be possible to find by SEARCHING..
How ever, because I'm in a good mood, I shall answer..
Yes, it is THEORETICALLY possible.
To acheive this, you must gain USB host on your Magician.
This can be done in two ways: Backpack + CF card with host support or a SDIO card with host support.
This can be bought from several suppliers.
Then, it's the driver issue.
A USB disk should be usable on the WM200x OS, but I do not know the size limit.
It might be about 2GB or it could be lots more.
So in real life; NO you can't use a USB HDD with your Magician.
This MIGHT be possible with the new Universal, but we haven't got confirmation that it has USB host support yet.
---- Edit ----
You might be able to do it if you can get a device that has host support.
Kinda like those gadgets that connects digital cameras to HDDs..
It just occurred to me..
How ever, It might be hard to use the magician to controle the data flow..
You'll probably need two connections to the device.
One for telling the device what to send, and one to receive..
Maybe, but unlikely...
chack out this things:
http://www.semiconductors.philips.com/acrobat_download/applicationnotes/AN10034_2.pdf
..this is a pseudo-host controller for PDA but i don't know were can find such a thing...

http://www.cooldrives.com/usbotgshcou2.html
The PXA27x processor inside the magician does support USB-on-the-go...
If you look at the USB connector in the magician, you will see that it is actually a MiniAB connector...
So, from the pure hardware point of view, the magician should actually be able to operate in host mode and, for example, control an external hard drive/pendrive, or even a keyboard...
The point is, that most likely, there's no usb-on-the-go driver provided with the operating system...
IMHO, I think it be a waste. These devices we have are not meant to host power hungry device like a 2.5' HDD. It be a waste to what our devices would be known as "mobile." I think better stick to SD technology but that is also another issue. As the cards get larger and larger, the more processing time and power is required to fetch data and back.
there could be a way ....
After reading this thread, I think there is a possible way of actually having certain types of storages connect to the xdaii. I've seen some bluetooth 40gb hardadrives that connect to the pc. They connect using two methods. The first method connects the harddrive as a wireless storage device and the other method connects the hard drive as a bluetooth network storage. Now as for the second method, it's actually supported in broadcom's and widcomm's pda drivers. So in theory, your device should detect the harddrive as a local computer on your bluetooth network. But now, the main question is, can the bluetooth data transfer speed be sufficient to allow mp3 playback without lagging and frame drops ?? Well that's one questions I'd sure like to know the answer for. Anyways, just liked to share this info with u, it could be useful to u or for others on this forum. Good luck.
can we use this thing for i-mate jam with sdio wi-fi card:

Hi!
I want to use my G1 to do some special measurements. For this purpose I've created a microcontroller board (Atmel ATmega8) that does that. Now I want to transfer the data the board collected to the Android phone.
Because of the high powerconsumption the G1 has while Bluetooth is on this isn't a real alternative for me - the measurements will last about 2 - 3 hours.
I'm not experienced concerning hardware access within Linux and Android but thought there might be a possibility to gain a kind of low level access to the USB port. I do neither need high bandwith nor real USB functionality - so might it be possible to create an own kind of bus using that interface? Do you have any other idea?
Thank you in advance!
If you use micro linux system, the ones that are like a usb port, a network jack and a vga connecter, you could script some adb commands and have it run every few seconds to upload the data, not an ideal solution. As far as I know the g1 doesn't support host mode. But if you have a micro linux computer in the middle, it could work.
Something like this
http://www.pcpro.co.uk/blogs/2008/08/27/a-real-space-oddity-arrives-at-pc-pro/
I'm sure there are other ways to do it, maybe check there how to make a serial port thread a few pages back in the dev section.
Just wondering if it is possible to send raw information(1 0/on off, whatever) to say the audio port or the USB port. I would assume USB would be easier to code for, but the audio port would be preferred if possible. The obvious application of this would be for custom external peripherals which would be fun to mess with. If anyones got any info or a link to some docs that would help immensely.
Thanks.
Using Audio to communicate is entirely possible. It has been done for decades over telephone lines. http://en.wikipedia.org/wiki/Modulation
USB on the other hand is a bit problematic, there's no host support on most android devices (there exist hacks for some) so there's no real way of connecting a USB peripheral to the phone.
Your best shot would be bluetooth I believe. I'm not entirely sure but you should be able to set up a serial connection over bluetooth.

If Audio is possible then I think that would be the best bet. I just found this bag of IR LEDs laying around from when i was messing with wiimote hacks, so i thought hacking up a little light coming from some port on the device, i could make a remote app for it.
Found some good information for anyone else wanting to make use of the audio port.
http://perceptumvolo.blogspot.com/2010/01/demodulator-updated.html
Using audio is definitely very cool, but for real world use it is too intrusive. You can't listen to music at the same time and all notifications will screw things up. Bluetooth just works and was invented for this purpose.
I've got a Sony Xperia z, and I want to start playing around with what I can do with it. One idea that occurred to me was expanding its radio capabilities. I basically want to turn it into a mobile ham station. I want to be able to scan HF, VHF, and UHF frequencies and transmit on them... I have a basic idea of how to make the hardware for this project to work, but I have no idea what to do on the software side. I know the Z comes with the built in ability to listen to FM radio and it uses your headphones as an antenna, so I'm making two assumptions with that in mind: the input source comes in through the headphone jack, and this source can be expanded to other frequencies depending on what I plug into it. The wall I run into is I suck at java development. It's been years since I've used any programming language, and I know even less about hard ware/software integration on a mobile platform. Can anyone point me in the right direction to pursue this project?
Ok, how about this: I'm willing to pay someone to dev the app for me. I started looking into what it would take for me to program this and it's way beyond the scope of my skills. I was looking at buying a laptop just to work on this project, but I would rather spend the money on a quality product. Here's exactly what I want it to do:
A. Receive
1) Receive radio signals in the medium wave (mw) band all the way up to the VHF band.
2) scan a range of frequencies, with step options (I.e. Start a scan at a user in putted freq and then stop at another inputted freq and have the option to step up in increments as low as 0.001hz as the user desires)
3) store frequencies into a scannable Database or store freqs into a database of freqs to skip over
I'm assuming this would all be done by pulling in a signal from either the headphone jack or micro USB port.
B. Push a signal back out through the same port. So basically a receive or transmit mode. I get that phones don't have a built in transceiver. I can do the hardware as long as I have a signal going in one direction or the other and an app to interpret it.
So with pushing a signal back out I would like the option to either broadcast a stored file or directly from the microphone.
Now as for pay I was looking at spending 300 on a laptop so I could push that cost to a developer instead. Any mods after the initial app is finished would come with additional pay. Add on mods that is, not debugging issues. Any takers?

Have you seen detailed specs on the radio? All I can find is that they identify if as "FM radio", so it is most probably just the VHF commercial broadcast band (88-108MHz). It is very unlikely that they would include a more expensive multi-band radio. A single-band VHF-FM broadcast band receiver would be much smaller than a multi-band receiver.
2) scan a range of frequencies, with step options (I.e. Start a scan at a user in putted freq and then stop at another inputted freq and have the option to step up in increments as low as 0.001hz as the user desires)

I think this part would be native code -- C language.

And this would probably be handled by an Android application in Java.

I don't think I understand you completely but it is very unlikely that this radio has a transmitter. It is very likely only the VHF-FM single-band receiver, 88-108MHz in the US. With a rooted device you could probably create software which will scan and otherwise select frequencies but it would be useless to make the steps any smaller than 200kHz, unless you wanted to listen for very low power interstitial transmissions. It almost certainly will not transmit.
Again, do you have detailed specs on the radio? This job isn't for me though -- I don't have the device and I no longer have a suitable working environment for this kind of work.

ADDED:
Also, FM is essentially useless below 6-meters, although there is some rare Ham usage in HF.

Oh the phone def doesn't have a transmitter native to it. My thought process is to hook the phone up to a transmitter through either the USB port of the headphone jack and have it transmit that way.
I want the phone to be the interface of the system. I was thinking something like this: techlib.com/electronics/allband (it's .htm, I can't post full links yet) inline with the antenna and the phone (I.e. Antenna -> receiver/transceiver -> phone). The biggest problem I run into is I don't know how to make the phone work with whatever I plug into it.
And yeah, I accidentally left the g off of .002ghz so 2000 kHz is completely accurate.

That is reasonable. You could even use the device to work some of the data modes on a suitable tranceiver. I think I've seen this done with the Palm, so the Palm might be a source for some of the code.

I have not looked at the USB interface yet -- my last serial work was RS-232 -- so I don't know what these things will let us do.
These Linux/Android devices have been out for several years and there might already be some software for this -- have you looked?

I have been looking around for quite a while now. There is a ton of software for turning a computer into a controller station(SDR), but not a lot for mobile devices. Wolphi .com is the best I've seen so far, but their device isn't what I'm looking for. I don't want to have a full separate radio, just an inline receiver/transceiver and have all other "radio" functions controlled by the phone. I dunno maybe I'm reaching here.
Thanks for all the input so far btw

Back in 2003 and 2004 I wrote a controller on Windows NT for my FT-897, and that was not a difficult task because I wrote it as a command line program -- no GUI. Are you intending to build your own radio, or just an interface for the phone/radio connection?
I looked at a few of the applications at wolphi.com and they all use only audio input and decode the audio signal. To control the device you would need USB, as you said. If no one has done this yet for any radio then maybe there is something in the USB implementation which limits it. I would probably have tried it by now if I were still licensed and had a radio to try it with, so I'm really surprised that a controller hasn't already been written.
I'm pretty sure I saw a controller written for a Palm PDA to control the Yaesu portable low power HF radio. I don't recall if it actually did any keying and transmitting though.
I don't think you are reaching too far. It seems to me that this can be done and it would be very useful if you do accomplish it.

ADDED 07:42:
After thinking back I recall that I had two or three connections between my radio and computer. An RS-232 serial cable connection was used to send commands to the radio and to receive replies from it. There was also one or two connections to send and receive audio; this was through two ports on the computer but I can't recall if it was separate connections or a combined connection on the radio.
The program I wrote had several options and one of them was to function as an echo repeater: it recorded a signal when the squelch broke and then retransmitted that recording when the transmitting station's carrier ceased. It was handy for other hams to hear what their station sounded like. An Android controller would probably use the same dual connection; for example, a command is sent through USB from Android to radio to key the transmitter then outgoing audio is sent through the headphone port; then the radio is unkeyed through the USB port.
The Android application will be a fairly typical Android application, except that is would communicate with a native Linux application that communicates with the USB port. This does not seem difficult to me and I'm really surprised it hasn't been done.
