Butchered keyboard

I have done very little research on my question. Looking at the pinouts on an XDA, and the pinouts on a mouse, would it be possible to butchera keyboard or create an adapter for a PS2 or USB keyboard to work with an MDA/XDA I??? II???? Let me know if anyone has tried.
I know someone else had butchered a mouse to work; I'm going to look for that thread now. ALSO, do you need a driver for something like that?

The developers successfully adapted an ipaq keyboard to work with xda, if you want to use a full size keyboard there is a cheap irda adaptor that allows this. Keyboards for pda's have dropped in price dramatically, check out www.ebay.co.uk and type xda or xda keyboard. There is a link for the full size keyboard adaptor in my earlier posts. Regards the driver, the special edition rom contains one that works fine for many keyboards including my genuine xda keyboard, only proble is that it activates after every reset so has to be disabled for wired gps function as it grabs com 1.

USB data input use on a non USB Host smartphone

Hy everyone,
First of all, thanks for this great forum which never fails to impress me.
I have a question which some of you might help answering: I'm wondering if it's possible to use the mini-usb port of my smartphone to get some data input.
Let me explain myself a bit more: I know that smartphones (HTC Touch for me) aren't USB hosts. However, the data connexions are still present.
Here's what I'd like to do: even though the smartphone can't control another peripheral, I'd like that external peripheral to send data to the smartphone, and the smartphone to use that data to control the screen. That would give an alternative way of controlling the screen.
The input would come from another touch surface, so my guess is that using the data to control the screen shouldn't be much of a problem.
So? Any idea if it's possible? What kind of platform/language would be nice to do that? C#?
(I have JAVA development experience, but I'm quite a newbie as far as Win Mobile devs are concerned. I'm willing to learn though
I think I searched this forum (and others) quite extensively before posting. If by any chance I missed a related post, I'd be glad to know about it

No ideas? Anyone?

Last up before I stop...

prob. not
i dont think that is technically possible. i think one has to be the host, and that host provides power. so to power the input device(im thinking keyboard) it would need the smartphone/ppc to be a host....
but i have no clue in this area...maybe someone could prove me wrong?

Hey, thanks for your answer.
The powering issues could be overcomed by cutting the cables and giving power from an external power source (I think several people have tried doing it, I need to find the links again). By the way, the peripheral itself is plugged on 110V, so there's plenty of available power
I'm not seeking here to "control" the device, just to aquire the signal it's sending... Does that seem feasible, or does the peripheral need to be somehow "activated" by a Host before sending anything?

Well, in order to get data, the host must ask the slave each time it needs some. Other things must be done by the host, like usb enumeration. That means there has to be a host or it won't work, unless you use usb on-the-go, but I do not know many devices that support it.

according to the qualcomm website, the msm chipsets support otg

[Q] Does any eInk Nook have hardware that could support a physical keyboard?

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.

Help with creating hardware keyboard

Hi everyone. I'm an Engineer and I graduated back in 2007. Since then, I've been a Systems Engineer working software and I'm fairly clueless in modern hardware development. I'd like to start playing around with android hardware creations. My first desire is to make a keyboard. I want it to be as simple as possible, to work through the usb and include a pass through so as to allow charging and other peripherals, and to have it's own power source that would be charged while charging the phone.
I'm not worrying about the casing/buttons/manufacturing right now, I just wand to get the hardware working. Anyone have any suggestions for getting started? I've found a few of the development boards through the android developer site, but the look like a bit of overkill for my needs. I do have experience with PIC microprocessors and so the pic one doesn't look bad.
Basically, what would you recommend and what resources should I be looking at to make this happen?

Can't comment on specifics regarding the keyboard, but I've programmed a lot on PICs and recently moved to an Arduino, which I've found much quicker to develop with. I can't post a link as I'm < posts, but google "Android Open Accessory Development Kit".

With cheap keyboards selling for under $5 I don't really see the point.
If you wanted to do some custom USB HID device, that's a bit different.
There are some things already to support this easily: http://www.ultimarc.com/JShopServer/section.php?xSec=13
If your goal is just to make a wired docking station,
I'd just use a back-powering hub and an off-the-shelf USB keyboard.

It has been done, look up "Motorola lapdock" and "USB otg android" and "USB host android".

honestly, the whole "making a keyboard" thing is just so I can get going understanding hardware development and USB access. I've got some ideas for accessories I'd prefer not to discuss, but I still want to learn the tools I need to do this.
Consequently, I'm looking for a way to learn to interface a simple hardware accessory with an android system. I'll probably need software and hardware.

so no more replys?

If you are just looking to experiment with creating USB hardware, the ATTINYs have V-USB, a software implementation of a USB stack. It should be fine for playing around with simple HID stuff. Some PICs have USB support too, but this V-USB will run on some of the cheapest attinys, if cost is a concern.
Google "HIDKeys - a USB Keyboard" for a a simple USB HID keyboard project which you can base your own code off of.

CS918s Android TV box

This unit is quite widely sold but there doesn't seem to be much of a community supporting it. There was some stuff over on DragonDevs, in particular a custom ROM by dvalin21, who also hangs around here, but that forum seems to have died.
The manufacturer of this box isn't exactly supporting it with firmware updates, last official update is over a year old, Android 4.4.2, I have some problems and was hoping there was a community out there to help solve it:
- remote control stopped working - LED still blinks on the device, but most commands not carried out by the OS (other than Power Off I think) - I have factory reset but it hasn't fixed the problem, also tried programming a universal remote from the C918S remote and it receives input but doesn't work with the box still
- xpad.ko not present, the box doesn't support xbox 360 controller out of the box, it seems, and I was hoping someone would've come up with a module for that (dvalin21's custom rom may contain it, but I can't download it and anyway it's old now). Annoying, all of these Android TV boxes would make neat little games consoles if only they included this support.
Any other savvy users of the OTT CS918S out there?

Hello! I have a CS918S also more than four years, very good, I had some problems got around with some roms. Maybe I can help on something. What problems your presented? If you have any error in English is due to be using a translator ...
