Screen Driver ? - MDA, XDA, 1010 General

Anybofy knows if the 4096 colours in the XDA can be changed by a newer driver to more than that?
Or is it the maximum supported by these screens?
Gear

Probably a hardware limitation. But I am sure the techies know more.

Yep, hardware limitation: 4 bits per colour = 12 bits = 4096.

How comes and the H/PC Jornadas had a 65k driver then?
So much hardware difference?

Multi touch capabilities?

Can someone tell me what is the multitouch capability of the G Tablet? I'm thinking of buying it as it is the cheapest Tegra 2 tablet, but I'm not so sure about the multitouch. Is it 2-point multitouch or 5 point? If someone with the tablet would be so kind to just download like Multitouch Test from the Market and see how many fingers the tablet supports.
2-point.....

Is this a hardware or software limitation?
Thanks!
Just so your aware. On my gtab multitouch is only reliable when the two points are not on the same x or y axis. When zooming in for example it is necessary to pinch diagonally or else nothing happens. Other have claimed this is not an issue on their gtabs, but this has been an issue for across several roms.

Difficult to say. The kernel only gets the data for 2 (simultaneous) touchpoints from the ATmega168 microcontroller that the actual touchscreen sensors (2 Pixcir Tango 32C sensor chips) are connected to.
Can the ATmega168 uC be reprogrammed to send more than 2 simultaneous touches to the kernel? Can't say.
Do the Pixcir Tango 32C sensor chips register more than 2 fingers at the same time. Yes, very probably.
Whatever the case, you'll need a ATmega168 programmer and all the chip-specific datasheets to make it happen.

Different model, roughly the same hardware specs, and not under the Galaxy name.
Microsoft is very specific about the buttons on phones using Windows Phone 7.
It can only have the 3 buttons, Windows, back and search in the front. Every other button: Volume, Power and Camera can only be on the side or top. The Windows button must have Windows Logo on it.
There are differences, Windows Phones prefer to use PPP whereas Android prefers to use RMnet.
There are a lot of rather stupid reporters out there which really don't have a clue what they are reporting about. These pple include the ones that states Apple iPADs are computer replacements, and it is the end of Desktop PCs. The day I see an iPad run VM ESXi, play World of Warcraft, and Encode a Video in less than 24hrs in 720x240 resolution is the day I would agree.

Android Device with External Multi-Touch Screen

I have a couple of tablets but my primary is my Xoom. I'd like to use the HDMI output and the USB to connect to a multitouch screen that I have. I've seen some older hacks that are resistance hardware touch screens that are more hardware. I'm wondering if this is remotely possible in the newer version of android like ICS on the Xoom.
Thanks

I bought my head unit from this seller. Had good communication with him, reliable seller.
I have RK3188 SoM 16GB in stock
IN USA I can ship you one for 85$ plus shipping
Hi ! thanks for your inputs
Did you notice a real difference between the dual core and the quadcore?
Thanks !
Is this compatible with KYD model?
I have the KD-c1908 from Pumpkin audio and they have been upgrading this unit.
the RK 3188.
They quoted me 70$ us shipped to me in canada from china for the board and 100 for the front higher resolution panel (complete minus som)
Now the question is do I do the display upgrade as well
I have noticed twice the speed when using google earth and I can simultaneously install several apps much faster than with the 3066. Not much of a benchmark I know but I would say it was worth the investment in the quad SOM.

The lcd is hidden under that, I haven't disassembled it any further than that yet.
There are 3 connections coming from the lcd/digitizer. In that picture there is: 1 two wire white plug for the backlight on the left. One small ribbon on the top for the digitizer and one long one on the top right for the lcd itself.
Do you have a picture of yours that would be similar ?

Hi,
I'm looking for a place to buy the RK3188 SoM to upgrade my JY RK3066 headunit.
I saw the link to aliexpress on the first post but they are asking $120 (!) for something that I see others got for $70 shipped.
Any place to order it for a decent price?

MTCD - Swap Radio Module TDA7786 for TEF6686

Update 27/07 - did not improve the radio enough to recommend this modification/change.
Apparently the TEF6686 module has better performance than the TDA7786 - e.g. 7786 poor sensitivity, selectivity, multipath issues etc. My JY TDA7768 is terrible, even with an RF amp, so to find out if the TEF is any better, thought I would try and investigated swapping tuner modules. Reviewing the GS board I have as a spare part against my JY, I identified the modules are pin-for-pin compatible.
Sucessfully swapped the Radio module from a donor GS board containing a TEF6686 Module into my JY board originally containing a TDA7786. The GS board was quite difficult to unsolder the module, perhaps due to leadfree solder, fortunately the JY board was easy, the desolder wick readily desoldering the module.
As for results, I have bench tested and RDS, tuning, audio etc is OK, I am yet to test in the vehicle. Will update this thread with results.
See attached images. Note that the JY case had additional mounts that over time might short out against the non-ground PCB tracks, resulting in complete failure of the unit!
Welcoming any questions.
Did the reception really improved?? And RDS AF fuction is working well with malaysyk V3 firmware?
also interested in this outcome

Hi,
The tef6686 appears marginally better, is more sensitive and appears to handle multipath better. Im not sure if I would call it out as a worthy upgrade just yet - need more time.
wonder if it can be bought on its own.. seems like just the chip itself which is surfaced mounted on the riser card as pictured above.. so this would prove difficult to install

Ive seen a suitable module available on aliexpress that would need some modification to swap a couple of pins. That is the TEF6686-TDQ-230V-186 (10 pin) - a whole $6 bucks US.

Next week this module come to me , so in the next weekend I have time to swap.

That's great, don't forget these are not pin-pin identical and will have to figure out swapping pins. Search for the manufacturer PDF and check against the mtcd schematic. I'll upload the module PDF later today.
Hi, final thoughts - the upgrade in my experience was marginally better - not worth it!

could be something else in the implementation, not just the chip itself.
i have 2 boxes, one with 7786, the other with 6686 and the difference in reception is worlds apart. I mean even with the powered antenna not connected to 12V, i had no hiss on any station received.
7786 with powered antenna is just fine, don't get me wrong, but 6686 is better.

I had thought about that but there's no difference in implementation I can see after comparing from schematic. Perhaps I had a 'good' 7786.
- MCU is latest HA
- Both modules are digitally controlled by MCU/i2c bus.
- same supply
- latest HA android 6.
There's really not much to it, 5volts, antenna connection, i2c comms and audio out. I get multipath noise/crackles from stations between 99 and 102mhz. Same between both tda and TEF.
Can you clarify what you mean by 'better'.
Hi!
Maybe there are some differences in the Radio Software used in the different HU. The Chip is controlled by I2C and it seems to be possible to activate or change some behavior of FM Reception through some commands.
Is it maybe possible to extract the radio Software from the good HU so we can try it out on different devices (with TEF 6686).
It would be really nice if it would be possible to control some of the possible configuration of the chip manually...

No differences in android and same MCU, MCU controls radio module via I2c. The "upgrade " has no discernable difference.
Any more details? I need a more sensitive tuner. I have a full power mast but my car is all SMC so the radio needs all the help it can get.

Sure - there are two different tuner modules and neither of them are 'better'. I suspect its hit and miss in the production of either modules.
If you have a proper external antenna, which is properly connected, there's nothing you can do apart from using internet streams or DAB if available for best quality.
thanks, do you know if these unit have the 7786 or the 7786M IC?

Are you sure ? Cos on MTCB/C units the AF doesnt work and the PTY is plain wrong (I have an MTCD unit now but I havent tested the radio yet, its still on the bench), but someone (deffo Italian I remember that) made some changes and got PTY to work correctly and I thought he did it by modding the app ratehr than anything on the MCU side. Sadly I cant remember exactly what thread it was in, or who it was.

Unfortunately the only way to tell on MTCD untis is to open it up, unlike the MTCB/C units where you can select the tuner type in facory settings, which is strange cos MTCD MCUs are much more powerful 32 but compared to MTCB/C's 8bit . . .
. . . or maybe there is a way ? - @marchnz's dmesg output mentions "6686" in the first post.
Hi,
Can someone help with radio module pins schematic for XD-6686AF-0. This is same radio module that @marchnz has swaped. I am forced to change main that is not pin to pin identical to TEF6686-TDQ-230V-86-TDQ-230V-86-R that I have from aliexpress.
Thank you
P.S.
