HARDWARE COMPASS IN ALL HTC DEVICES WITH THE AK8976A CHIP?!?!
As said by some (tuxhero for example => here) ,the Touch HD has a real hardware compass inside waiting to be activated by some clever dev.
If you are such a dev here is some bounty for you as a little encuragement.
Goal:
Build a little proof of concept application (for winmo) and open the sources for all xda devs.
As for the bounty:
050$ Draque:the_Plaque
050$ maati + additionl 100$ if it works in google maps. (But only if released before the HTC Leo
050$ tids2k
050$ LC40
--------------------
200$

reserved for more

It's nice but i am not sure. Please don't go on my words. Some one said that me and i said it to you. No real Proofs.

i thought the new Samsung OmniaII/pro was the only WM devices that has hardware for a digital compass

what other devices has this

it might be worthwhile to extract the compass application from the omnia2 rom dump for testing purposes

Is this screen from the omnia2 or pro?
And is this a test app from microsoft?

It doesn't work on my HTC Touch HD.

Hi, there is a test app that comes with the HTC Debug Tools set for this compass, some time ago I analyzed it and determined that it was likely present in the hardware, but I have never gotten it to function on my Raphael.
Lacking an HD device to test with, I can't say if it works there, but I can provide the app I will attach it shortly.

About the AK7986A sensor.
In the test application under help:
AKEMD 2007 (name and year is viewed)

The app is not signed.

Da_G, i just tried on my HD the soft you shared to us;
-open and close seem to be ok but nothing happens
if you choose to re-open without closing before it will give this logical error:board already connected.
edit:
-init, start and stop give this logical error without open : board not found
-init, start and stop give this logical error with open : board already connected
So the soft is probably ok but for our HD we need to use the good input/output in the dll

You have to copy the DDLs to Windows folder. However, "init" or "start" from the menu only brings up an error message "The board is not connected". Some graphical glitches as well ... seems to be made for QVGA.

So with a small possibility that Layar (3.0 ?) will come to Windows Mobile based phones, we really need a working compass for that to work.
Anyone still working on this? Would be a great addition for all our HTC devices!
Ps. For those who don't know Layar yet; it's an Augmented Reality app for Android and soon iPhone 3.0. Go visit http://layar.eu/ and think of trading WM for Android .

Same happens on a Rhodium, would be very nice to have it working.

It needs a device called ECS1:, this driver is not present on Touch HD.

Maybe first we should check if any of new WM devices actually have AKM chip inside?

Does Windows Mobile provide any kind of a compass API? How difficult would it be to write a program like Layar or Wikitude or build compass support into Google Maps?
I'm thinking about buying an Omnia II or waiting for the HTC Leo, both should probably have the compass hardware, but how about any apps that use the compass? How long do you think it will take until we see an augmented reality apps for Windows Mobile?

Does anyone know which compass is used in the htc polaris?
Ar are the cab files for the polaris hw compass available by chance?
btw: if anyone wants to raise the bounty for this project just pm me or write it directly into the thread.

I did some more research into this, I am working with a driver for this for raph right now..
Let's see what I can come up with

Use phone as a universal remote control

Is there an app where I can use my phone like a remote control similar to a harmony? If not, what are the prospects of developing one? That would be pretty cool if you could make this thing an all in one, and with its bluetooth capabilities, run the PS3 as well. Anyone interested in giving it a go?

Aren't most remotes IR? I may have missed it, but I don't think the EVO has an IR emitter. I suppose you could make a device that plugs into the headphone jack (or one of the other jacks) and come up with something that way, but then you'd need to keep track of a separate piece.

The only way you can do this is with a hardware update. And an application, but that will take some development.

Below is the closest you'll get until googleTV comes out (then there will be a dedicated Harmony app).
http://code.google.com/p/android-xbmcremote/

would be sweet. This would require a BT-linked IR transmitter somewhere in the room that could convert the phone's BT signal to IR.

I am pretty sure that the PS3 uses bluetooth in its controllers. I have a harmony and it isn't compatible with PS3 due to the Harmony using IR and the PS3 using bluetooth. This would be a pretty sweet app though.

this works for the PS3. Here's a link to what I'm talking about: "mobilesrc.com/MobileRemote.aspx"

just buy a Harmony Remote for $50 and you'll love yourself for it.
the 550 is one of the best investments and one of the more practical and more future proof piece of electronics I own.

I already have a Harmony Remote. Does nothing for PS3, and even if it did, it wouldn't function as a keyboard for said PS3.

Harmony makes a ps3 adapter. I have it and it works great.
Sent on my cursed EVO

Checkout the Logitech Revue. Google TV, access to your network content, harmony remote control functionality for IR devices, etc. Logitech PS3 adapter may complete the picture.
7/12 - If your television supports the Anynet+ protocol, you can use your tv to control your PS3. With Harmony Link you could even build macro to autonavigate through the menus as desired.

Also there is a app if you have a tivo to control it through your wifi network. I couldn't get it to auto detect the tivo so i have to manually asign a ip address to the program to get it to work.

Debian with gnome on A101

Hi everybody,
I managed to install a version of debian (with gnome) on the A101.
Most of the things works but the wifi is not yet fully operational. I work on it right now.
Edit : Wifi activated, and patch for sound available
Here is the file rootfs.img into two parts. For now, the only version is in French but soon I will upload an English version.
Edit : Supports english, see wiki for instructions
For more informations visit http://www.debian-archos.com
I will check this thread if you have any question about my debian.
Links are here http://www.debian-archos.com/download-debian-for-archos-gen8
Login : debian
password : debian
su password : debian
Enjoy
**Edit**
Added a tutorial on "How to create a rootfs.img" on my website
*******

That is very cool. I don't speak or read French, so I can't really check it out, but how is the speed compared to Froyo?

it take time to launch but after it's pretty fast, but the interest is primarily to release all the capabilities of the tablet!
And don't worry, i'm making an english version at this time, but it takes a lot of time, so be patient !

Well... that sounds very interresting.... Did you get the touch-screen working?

Yep As you can see on youtube : watch?v=m0gcIN6Vzo8
And it's not a VNC!
USB master works too, you can connect a keyboard, usb key etc ....
For the wifi I manage to connect via ifup and to ping google, but the internet does not work ... If anyone has an idea it would be with pleasure.

At this time the orientation Sensor and wifi doesn't work. Some internal devices like the screen are not recognized but works anyway, i have making a drivers package, but i only know the "isnmod" for integrate them

ok, let us know when you manage to get these working, almost done downloading it!
EDIT: I'll try and see if i can get them to work and if i do, i'll let you know

So, things that currently don't work are wi-fi, bluetooth, orientation sensor, hadware graphics and audio... a part from those issues I'm impressed on how well debian runs on the archos 70

Debian or Ubuntu on A70 it
Hello,
Really nice work, i hope you get the WIFI 100% and sound so it will be perfect for me !
As someone told you on your website, the coming Ubuntu release named "Natty Narwhal 11.04" will get the UNITY and GNOME interface, and it will be easy to switch from one to another, UNITY is also what looks like the Ubuntu Netbook Edition screen.
Maybe you can try to get UNITY inside Debian ? you will find more here :
//help.ubuntu.com/community/UbuntuNetbookEdition
Ex :With Ubuntu 10.10 a new desktop called "Unity" was introduced as default for the Ubuntu netbook edition. The new interface should use the small desktop of netbooks more effectively, give a better structured access to the installed application and be more touchscreen-friendly. It is already planned to use Unity as default desktop for Ubuntu 11.04

I am really exited for this. I have always wanted to use Linux as my main OS, but because of certain things I need (i.e. World of Warcraft ) that don't work well on Ubuntu, I always end up uninstalling and going back to Windows.
So I would love to have a nice Ubuntu/Android dual boot system on my A70. Keep up the good work.
And guys, don't forget to thank the OP. It's great when people do things like this to give us non-dev types better products.

The main problem is screen calibration. The pointer remains about 5 mm away from the screen borders, which make the menu totally unusable.
But as the center of the screen is usable, I managed to launch some applications.

head unit Xy auto 8227L_demo

hello everyone, I have the following equipment
Android: YT9216BF_00007_V004_20191226
Android 801 GO
can pro 3.0 (8227L) HIWorld -04 ~ 07 Megane 2
DDR: 2G FLASH 16G
CPU: A7 1.3GHz x 4
Radio: NXP6856
MCU1: 3.1 (8227L)
so i wanted to upgrade to android 9.1 and if possible change the ui which is quite ugly and the radio has a basic and ugly aspect.
can someone help?
originally it was 9.1 but I did a system restore and it became 8.1.
before I had access to the engineering setup and now asks for a password I don't know
Best Regards

can someone help me please?
I have searched through the forums and there's a lot of information but I don't know what to do also because I'm not experiente in this area
What can I do?
Upgrade? How?
New radio app that also work on background off louncher
I installed agama louncher and dosent show maps guide in center of de main screen of louncher
In settings I can choose ui from 1 to 5, doesn't change anything loooll
I've seen that hare many variations of software fromYT9216BF_00007_V004_20191226 and after the yt9216 it changes, I've no idea if will make possible the installation or not.
I admit....I'm lost
Best regards

AT YOUR OWN RISK, you could try this package: https://yadi.sk/d/Faw1HGZrNCwMCQ
nitial firmware in which some of the sound adjustment functions do not work, even the activated hifi button does not work, the equalizer does not adjust the frequency of sound on the radio, partially compatible with the YT-9216 GU.
In firmware YT9213A_00005_V004_20191218_HIFI for GU 9216 / 9216_AHD / 9217 (2/32) all this already works.
I tried to leave it unchanged, but nevertheless, there was a slight modification. Namely:
TWRP
ROOT
VIPER
Radio_RDS from mclaught with the completion of the button background
Editor for radiomclaught
Window skin Settings
Skin window GPS Test
Returned the buttons and the slider in the "Sound Settings" section
Set the equalizer with the HiFi button.
That's all I ’ve done ... I don’t know how much more, unfortunately ))))
Things to remember:
Perhaps, after flashing, you will have the device’s firmware name changed to YT9213A
Immediately after loading, reboot the device
Sound on a volume scale of 17 or more -18Vol, has a slight "plug". Not critical for me.
After a full installation and overload, adjust the sound using standard tools (EQ, hIfI, Viper). I really liked the sound (installed audio processor CSC37033 and ULF PA2030A)
Skins from the stitched and working device YT9216C_AHD, under the spoiler.

The stock bluetooth is locked down by the manufacturer. If you get a USB bluetooth dongle that is supported by the Linux kernel you will be able to connect other bluetooth devices to it.

Yes you might be able to load a separate BT device and have it function with the hacked BT stack, but you won't get the standard BT stack. Period. Yes I have reproduced on my MTCD/E.

I am not exactly sure what you mean by functioning with the "hacked BT stack". Android is based on the Linux kernel and the USB bluetooth dongle is supported directly by the kernel. The software interface for pairing devices can easily be changed with apps from Google Play Store or F-Droid. I use my bluetooth dongle to pair to my BluDriver OBDII adapter which will not pair with the built in Bluetooth.
So, are you saying that I shouldn't be able to do this or is there some other point that I am missing here? Not trying to be rude here just trying to understand. Thank you.

What I am saying is that the chinese developers wrote their own BT implementation, the standard Android rules do not apply.

What the manufacturer's did to the Android software was not done at the Linux kernel level. Yes, the default bluetooth software will only pair with certain devices but that does not stop the Linux kernel from working with a USB dongle to pair with anything you want.

Parking sensor interface for head unit

Hi!
I'm working in a hack for a universal parking sensor and I have the microcontroller code ready.
I would like to know if there's some Android developer interested to work in this project.
I don't pretend pay for this app. The project can be open source or the developer can sell the app in the Play Store.
The initial idea is to show the sensors readings in the head unit to eliminate the needs of a additional display over the console.

}
This feature is available in some stock head units as show below.
The app should work in float mode to allow the user to place over the rear camera image.
Also it could work on smartphone like FenSens.
Also there's this project as reference.
I have published some information about the circuit for hack the parking sensor and a code for test in this repository:
GitHub - FernandoGarcia/ParkingSensor: Interface for a parking sensor with 8 sensors.
Interface for a parking sensor with 8 sensors. Contribute to FernandoGarcia/ParkingSensor development by creating an account on GitHub.
github.com
The final code is not available yet.
Basically the controller will send a JSON via BLE to head unit.
If someone is interested let me know.
Best regards.

This seems damn cool how far have your gotten with this?

Hi!
I have the sensors installed on car and the microcontroller is sending data via BLE.
I can see the data using "nRF Connect for Mobile" app running in the head unit.
Missing an interface as shown above.
Best regards.

seen your github page seems like your solo working on this im impressed how far you gotten.looks like your inching closer and closer to having something amazing

Looks brilliant, it would be great if the app could work with factory fitted sensors too.

It's complicated because each manufacturer has your own communication protocol.

Hey @FernandoSouza - mighty cool project. Did you get it to work? I would try and replicate it once it runs reliably, if you permit. Quick question - many Android HUs can interpret sensor information that comes via the canbus, had you considered going down that route? Again: kudos for your work!

@FernandoSouza
Having been looking around for something like the end result of this, I would be quite interested in seeing what I can put together in order to display the output of your sensors, if you were still looking for an app developer? It's been a little while since I've done some mobile, so I'm a tad rusty, but if you have details of the message format you're transmitting, I can see what I can come up with for it? I am quite happy for any app code to be released under the same terms as the rest of the project details

This project is awesome! I've just stumbled upon this and would really like to help with development! What's the current status?

Hi!
I'm so sorry, I have missed some posts here.
@17sixa The MCU side is working fine but I haven't the Android UI for the head unit.
Canbus I think a little bit complicated since each manufacturer has your own protocol.
@Shojy the message is a simple JSON as you can see in green in this image:
Any help would be so much appreciated since it could be a kick to start the development on Android side.
Best regards.

Nice job.
Still, RFCOMM is the lowest of the food chain.
Maybe look into custom GATT and no JSON?

Hi @Renate !
I think BLE is cheap and simplest way to make a MCU talk to a HU but any more specific suggestion is welcome.
I have no idea about what GATT really is.
I'll publish the final code on Github so I can get more help to improve it.
Best regards.

BLE is fine. I like BLE.
I just meant instead of sending JSON over an unstructured RFCOMM it might be cleaner just sending GATT "characteristics".
Then you can "read" a value if you like or get a "notify".
Technically speaking, you're already using GATT. See that "Generic Access" at the top?
You save having to use Jackson or other JSON parser.

@FernandoSouza
Wow, that's just what I've been looking for since I installed my M700S. I will follow this treath. Unfortunately I can not help because I do not understand anything about computer science. Anyway thank you for the work you do and for what you will do

Hi!
I have published the current code that I'm using in my car actually.
It's available in this folder.
@Renate if do you have some knowledge about ESP32 code when you can please, take a look in this pieces of code and tell me what I have to change to use custom GATT characteristic instead JSON.
Best regards.

Hey man ,
I think this product is exactly what you are looking for right ? : https://www.aliexpress.com/item/100...3!sea!MY!185370336&curPageLogUid=EoVLhuQVO0C7
But instead of CAN BUS , implementation by BLE and overlay also sound neat

Good find! Thanks for the lead, will be interesting to see what units it is compatible with.
Keep in mind that units installed with canbus, this unit would take over canbus, disabling any factory canbus integration, such as heater controls.

Hi!
Thanks for your reply!
Yes, I need to work with BLE to make the APP compatible with any car model that has an Android HU.
The overlay is important to put the parking sensor interface over the rear camera image.
Best regards.

So far , from what i see , the speaker is also act as can bus transmitter to the android headunit . it connect via DISP port on the sensor box . My question is , does all sensor box using the same protocol when communicate with the DISP ?
Blue connector is to connect to the android headunit via CAN BUS port.
Yellow connector is to connect to the DISP port in the sensor box

I believe that the main box works as any other model and the buzzer can be replaced by a display like this:
The buzzer unit translates the main box signal to CAN protocol..
Each manufacturer has a protocol for main box that should be decoded as you can see here:
