Thread: Mini MK802 install attempt. Have questions.

I believe that is too small of a unit for you to do much with. They are cheap but you are asking it to do a lot.

You would be better off with a Beagle Board or similar. Or you could go to a place like Boundry Devices and pick up a small Atom Processor based board or if you can run ARM based Linux then something like the Free Scale i.mx6 would be well worth the difference in price.

There are other boards available under $150 that would work much better for your project than that thing.

As you know all touchscreens need a driver to convert the touch signals transmitted through the usb into mouse signals for the OS so if you can find such a driver for Android then it should work.
It has built-in capability for usb wireless mice and keyboards but so does a standard PC yet they still need the touchscreen driver.

Can't see why a usb hub won't work...I would suggest a powered hub because you might not have much current capability in such a small device.

Yea, but I like the size and simplicity. Im so tired of having a complicated install, lol. These units do all that I want, im just not sure if a touchscreen will work on them. I dont know if you know redheadedrod, but I have wasted tonsssssssssssss of money and in my opinion not got anywhere. I feel that by going the Android route, I will have a setup that is 97% worry free and is geared towards a mobile environment. Its to bad I was so pig headed and praising that the PC was the all mighty God of the car pc. In my view, its now just a fading relic.

I want something I know well (Huge Android fan). I want something thats not going to drain me of money anymore. Remember I have to by everything in multiples of six.

It was confirmed from another site, http://www.squidoo.com, that you can use a USB hub. That means I can use the KVMP switches, since they are seen by a normal PC as a USB hub. One concern that is really left is the touchscreen part. If I had to find a driver, would it be the one for Linux? I dont think they would have a native one for Android, since they use multitouch screens. The shared unit will be the upgrade from the MK802, the MK808. It has dual core and should do well in a shared environment. Now that I know hubs work, I just have to hope this unit will allow six touchscreens.

I have some other questions, basically my new idea is growing. I have decided to change my main dash screen out with a Nexus 7. To bridge the audio, I am simply going to use a 3.5 headphone cable and go from Nexus to Car PC audio. I still have to work out the phone and texting part, but I am sure Android has solutions.

Here is where I have questions. I have a serial OBD2 scanner, which has a serial to USB converter. I know for a fact drivers will be none existent. Would it be better to just buy a BT version, but if I do that, how will my phone pair with the Nexus? I also have the HD Radio and TPMS, which I would still like to use. I intend to keep my Car PC, so is there a way I can have them there, but the Nexus somehow accesses it?

What you may want to do is similar to what I plan in out Sienna. Get as many of these (http://mtxone.com/products/matrixone) as you need for remote screens and something like a nexus7 for the control point. I plan to use the matrix one's as rear viewers with bubbleupnp installed so they can all select their own media to play or I can force one open for them, for the smaller kids. Then on the control unit I can still have my music playing through the main speakers and/or use nav. Those Matrix one's cost about the same as the MK802 but you don't have to worry about making the touchscreen stuff work.

Well I went ahead and bought a MK802 to test, but also bought its bigger dual core brother, the SS808 (MK808). Problem is my car has already been modded and fitted with the screens I have. I was doing some reading and it looks like Android has the drivers built in. It can sense when a 4 or 5 wire touchscreen is connected. Also any Android device with Android 3.xx and up can connect multiple USB devices, granted there is a software to run it. Since Android has the drivers, I should be set. Will not know till the units get to me.

Ive basically changed my whole setup. It is now Android powered. The front dash will get a Ainol Novo 7 Flame Android 4 Tablet (ordered). This will link with my Nexus for 3G/4G, Phone and Text, and GPS. Then of course the Android Mini PC units for main media control and independent media control. I am keeping the Car PC for audio processing (the tablet will connect directly to the PC), BT Headset emulator, Media storage and management. Every feature I thought only a Car PC would have, I have found a Android solution for. That includes USB OBD2, GPS (the tablet doesnt have it, but it can share the Nexus GPS), and even TPMS (its called TireHawk Bright+, but also seeing if the PC version most of us use can be adapted).

Rewind..... Are you saying Android devices with USB host can accept the usb plug from a touch screen and the android ow will recognize touch input?

It depends on the brand of the TS. I noticed that Lilliputs work, with only a small flaw that its inverted. My assumption is that you can locat the driver and flip up and down to work correctly.

As far as my VM70 units, it will not see the TS at all. A driver has to be written.I have been reading that I may be able to take the Linux touchkit TS drivers and embed them into Android and get functionality. Its the only hurdle left and I got a full PC install thats actually geared towards mobile.

Well they sell the ts kits with the controller on ebay so I actually wanted to fabricate my own wired touch controller onto my armrest at angle but have it be transparent so mounting it on plexiglass would be the idea for me.

Over on my project thread, we have been talking about TS. The people chiming in say that a capacitive touch screen may work. They are native to Android. So thats the route I am going to look into, but also look into ways of getting the current panels to work. Either way way I am going to keep my screens.
