Hi all,
I'm new on this forum, and I'm building a DIY tablet with Orange Pi & A20 SoC (maybe I will change for LeMaker Bass) & Android 4.2.2 (v.5 with Bass).
This is a 17.3' screen tablet. I already have a IPS screen, and all works, 4h30 autonomy
Anyway, now I'm looking for a cheap but quality solution for a touch screen. So, multitouch, and easy interface: USB is the better choice for me.
I have seen the "HP ENVY TouchSmart 17 t" touch screen. About 90$ in Chineese shops. The others touch screen are about 180$, because not a serial manufacturing...
Here a pic of the PCB (attached file)
So, my question:It seems that the chip is eGalax (so no problem for the driver: /drivers/input/touchscreen/usbtouchscreen.c), and the interface looks USB (by looking CN1 ref) -> VDD, D+, D-, Ground
But, because of norms of USB VDD, D-, D+, Ground: D+ and D- are inversed... It distrub me a little.
Does somebody can confirm this is really an USB device ?
Thanks

Hello,
on htc hero, we have an adapter cable for video output?
Because I want to buy a TFT touch screen in my car is connect my htc hero on the touch screen is used in my car.
Thank you
Sorry, I don't think that is possible. As far as I am aware, the only output you can get from the device's USB port (other than USB and charging input of course) is audio output and possible (not sure) microphone in.
I am not aware of any video-out capabilities, and certainly have not heard of touchscreen input to allow another screen to be used. Unfortunately I don't think this is possible.
thx reply anon2122 ...
no luck for me
I saw discussion of this on the Dream forum.
It sounded like it was possible, but would require opening up your phone, and soldering new connections onto the MiniUSB socket.
I think no-one tried it
when a tester?
I'm leaving ...
but I need the schema.
I have heard something about Video long while back. But can't find that info again. I too am interested.
here is the pinout for the Hero's funky usb port: hxxp://pinouts.ru/PDA/htc_extUSB_pinout.shtml
still no solution in sight?
According to the pinout, there is no capability for video out through the port. There's
1 USB VCC +5v
2 USB Data -
3 USB Data +
4 N / C
5 USB GND
6 Left Audio +
7 Sense
8 Audio - (GND)
9 Switch (Talk)
10 Right Audio +
11 Mic +
12 Chassis Ground (GND)
but no mention of video. Any video mod would involve hacking the inside of the phone, replacing the screen connector to a new, compatible screen, dealing with touchscreen issues and resolution (latter easy to sort by a new ROM).
So, no, and I don't think there will be one for a long time (if ever)
I found a previous thread about hacking Vizio TV's but I noted a lot of the folks trying to gain access were doing so through telnet or over the network. I just picked up a Vizio M551d-A2R, and taking a look at the mainboard on it I see a couple of un-populated headers that could be a serial and/or JTAG interface based on the traces and connector layout.
Anyone have experience with trying to gain write access to hardware via I2C or Jtag that could help a relative newbie hack his TV to pieces?
(Before you ask, I'm doing this more for the fun of it than any practical purpose, and who knows, maybe we'll see a Vizio TV section pop up on XDA if this goes well)
Technical specs on the TV:
(U20) Mediatek MT5590 (looks like a specially built version for TV's and I cant find a spec sheet)
(U4) Micron 16GB NAND (located on bottom)
(IC9/10) Nanya 128mb DDR3L x2 (256mb RAM total)
(IC11) Nanya 64mb DDR3L Ram
(IC4) EEPROM (cant read label properly)
(RN21) Unpopulated, looks like I'll need to add a bridge or jumper resistor here as it appears to be sitting on the I2C bus traces
(CN3) JTAG(?) header
(CN33) I2C Serial Bus header

vizio d24-d1
yes, i just jtag this vizio d24-d1, you need to use a 3.3 volt usb to serial and then solder the ground, tx and rx.
then you can load a terminal on whatever com port the usb to serial you set to use. email me if you need help finding the pins on the board.. and looking at your photos CN20 is probably it
get a meter and test which is ground usually one on left or right
then so the order would be
GND,TX,RX,3.3 volts, (dont hook the 3.3 volt to anything)
but the tx and rx will show 3.3 volts as well
Are drawing tablets such as Wacom, Intuos, and Huion not compatible with Android tablets in general?
I plugged in a Huion 420 via USB OTG and all I got was a white dot in the middle of the screen. It says that it's connected as a mouse, but it remains fixated at the center with no cursor trailing anywhere else on the screen.
Is it a driver issue? Is there anyway I can get it to work since it has shown to be partially working?

Well the 'huion 420' which is a good product by the way...I use it all the time but..with mac yup it's only compatible with either pc or mac. You cannot use it with the note pro because it needs certain drivers to work which act as a link between your device and the Cpu so each driver works specifically for a specific hardware otherwise it cannot establish that 'link' so well there is no way for you to connect this with the note pro, however, you could use your tablet as a drawing tablet for your pc (reply if insterested i'll tell you) so well that's it..Glad to help! By the way I use my tablet for drawing using 'Artflow app' its better than 'stock sketchbook' has greater pressure sensitivity, options etc. Check that out too! Thanks for reading!

I heard that there's an old Intuos small you can plug into Android but now, I dunno if the drivers are still present on recent builds... For sure new tablets doesn't work at all but yes that would be an awesome option indeed.
Not that I know of, no. You could probably use it as a mouse if the tablet has that function, but as an actual drawing tablet, probably not.
I'll try my Wacom Intuos 4L when I get home.
That said, not entirely sure why you'd want to use a Wacom tablet to draw on a tablet that is a Wacom tablet.
Now, using the NotePro as a drawing tablet, that you can do with VirtualTablet. (I do that all the time, incredibly useful.)

Hi,
I have this tablet: http://en.senter.com.cn/products_detail/productId=183.html
It has this type of https://www.graperain.com/ARM-Embedded-MSM8916-System-On-Module/ SOM with MSM8916 CPU. Actual SOM inside the tablet has different marking on it but it looks exactly as the one in the picture. Dimensions are also the same. I googled a little bit and the SOM probably contains PM8916 power management IC. The board that SOM sits on contains ADP1612 boost converter that genereates 5 volts for OTG (at least I think so).
The tablet runs 5.1.1 Android (32 bit) with 3.10.49 kernel.
The problem is the tablet can't be charged while the USB is in OTG mode (I want to connect USB webcam to the tablet and at the same time to charge the tablet). This functionality is called accessory charging adaptor (ACA). I tried to connect OTG cable with 124 kohm resistor and to supply 5 volts for USB webcam externally but this way tablet doesn't enumerate the webcam.
Do you think ACA can be enabled in software? I don't need the tablet to generate 5 V for OTG, I can supply it externally. But I want it to enumerate the webcam and to charge from my external 5 V supply.
I extracted device tree that the tablet uses - http://gaminn.sweb.cz/dt.txt . Do you think it is possible to edit it in order to enable ACA?
Hello everyone.
my phone died at the same time as my PC last month (a coalition).
I bought the s23 ultra for its power hoping to be able to use it as a phone as much as as a PC (android pc).
Could you tell me what hardware is needed for this conversion (I already have a Bluetooth keyboard + mouse) ?
Best regards
Here is my setup (plug in a monitor for Dex to get a more desktop experience)
Dock 1 - (pictured) https://smile.amazon.com/gp/product/B095F4FZZY/
Dock 2 - (Raised) https://smile.amazon.com/gp/product/B08PFC2ZW9
Both of these have HDMI out and also plenty of extra ports for connecting things.

I had something like this and it works great if you are just wanting to hook it up to Dex. I have something similar and is great to have.
I switched to the Dock style like I linked because it allows me to use the phone without the need of an external display (but has the option to use one).
Either solution would work great and the best thing is you can plug in full size Mouse and KB to either option if you do not want to stick with the BT KB if it is not full size.
Thank for answers !
I've got something like that !
so Waiting for my S23 and let's go !!!
question more,

There are a lot of options to use S23U as an Android PC.
You can use a USB C dock. There are some docks that are more designed for desktop setup to be PC. I would suggest getting something that has passthrough power charging since there is only one USB port. Technically you can use Qi charging pad, but wireless charging tend to make batteries run hotter, which can shorten the life the battery in the long term.
Since Samsung has Dex on many of its phones, you essentially only need to hook the phone up to some kind of display. After that, it's about making it a better experience. This is connecting a keyboard, mouse, and so forth. I personally like Logitech ERGO K860 keyboard. Ergonomic, but has Bluetooth and a wireless receiver, and can be synced up to 3 devices. The Logitech MX Anywhere 3 Compact mouse it nice. Small, thus very portable. Also can synch up to 3 devices.
There are also lapdocks such as NexDock and Uperfect. These are basically like laptops but with no central processing or storage. They're a keyboard, mouse, and monitor. They're still pretty early in the product cycle and haven't gotten to a general population use. I have the Nexdock Touch and NexDock 360 wireless. They work very well, but there can be some quirks. The phone is all the CPU, GPU and storage. Most modern phones released in the last few years have the power any decent laptop; maybe more powerful in some cases. These can run $250-$600US, which some argue you can get a cheap Chromebook or laptop. The nice thing, when you upgrade your smartphone, you're "upgrading" the power of the "laptop". With NexDock, you can access the internals, which means, in theory, you can replace the battery. If true, it means you can keep/use the lapdock for years. I think YouTuber, JuanBagnell, does a good job explaining the pros and cons of lapdocks. He focuses on most people's everyday and most likely uses. He does not use the usual benchmarks; it's how certain programs actually perform. He has reviews of several Nexdock and Uperfect. YouTuber, ETA Prime, has some interesting reviews on some of them too; he is more gaming focused
You are going to want to read/watch information on Dex. It's one of the more "refined" desktop environments with smartphones. It's not like ChromeOS. Google hasn't only recently started to add a desktop environment to Android. It has a more Windows feel to it. Not apps play nice with it. Also realize, this is Android based. Thus, you're not going to be able to use Windows or MacOS applications. It has to be Andriod applications. Some apps have incorporated the desktop environment. Others not so much so they can look weird. Some applications are designed not to work in the desktop environment. On a side note, you don't have to use to Dex. There is an option to mirror your phone.
If it wasn't for a few specific Windows-based applications, I could literally ditch the home PC. This is why my home PC is very small and not a powerhouse. I recently upgraded to a Minisforum with Ryzen 9 integrated H6800 GPU from the NUC11. The GPU was an issue with a couple of applications I run and was starting to get annoying.

Looking for this answer too, did you find which DP version S23 Ultra usb-c port supports? 1.4?
I don't think the S23 is purely dependant on the USB C adapter being HDMI or not. There are USB C to DP adapters. I think it's more, does the hub support the output of the S23 into a DP signal that the display will accept.
The VGA thing, that will probably require another adapter since you're going to need to change a digital signal to analog. I haven't checked in quite some time, but you may have some luck finding an adapter with HDFury. I used them a long time ago for HDMI to Component video (RGB). It may be kind of pricey.
