HDMI interface to the touchscreen

[BearBu]

Great projects @artsci and @BearBu!

Just curious as there’s an interest- is it possible to split the front and rear camera outputs to separate buffers for recording? I know there’s an interest in this, it’s a feature that Tesla has promised, and folks usually try to supplement with a separate camera. I’d be happy with a simple box that has a card reader and records off the video feeds. Is this technical feasible?

We have a board that taps the signal from rearview camera and converts to 720p HD AHD signal (which to be connected to Dashcam + Digital Mirror) for recording issue.

Details are in the following link:

I'm interested in this. I am planning on installing the FLIR PathFinder2 Thermal Vision kit in mine,

Did anyone else remember Cannonball Run just then?

This is a great little project you have going here. I would love something like this.

First attempt of image from the laptop computer thru HDMI port.



The output signal was not so stable and need some time for trouble shooting

Next step is to test the MHL detection function

Behind the Green.... Oh wait you meant the Thermal Vision... never mind.

This looks amazing. Will there be an audio feed to the stereo too?

Excited to follow the progress!

I suppose this is video only, no touchscreen and no sound. Would be awesome to have AUX audio input, or sound over HDMI would be awesome, but sadly not possible.

Well which ever device (android, iphone, PC, etc) you used to connect the video will probably have bluetooth. Just connect that device bluetooth to the car and you have audio.

Good luck getting the audio to sync.

Actually, the inverse might be possible with this setup. When viewing video directly on a mobile device, the problem is that the BT audio normally has a slight delay behind the video. If the developers of this solution were to incorporate a time delay on the video to compensate, it would be perfect.

Amazon firestick seems like its the best device so far to be used with this unit. It supports Bluetooth audio for an output, supports MHL (if it ends up working), and has an rf remote that will work wonders.

Lastly, lets not forget its super tiny

My roku has hdmi to TV and I listen to audio via headphones plugged into the roku remote. There is no sync issue with wireless audio. I also play video all the time on my tablet in the car connected to the bluetooth audio. No sync issue.

You are right , it is video only. The audio input has got to go thru Bluetooth

It is still in development stage and not quite yet to be a final product now. Please allow us some more time for more compatibility testings.

 

[BearBu]

Project status update:

- HDMI port testing ok , output to touchscreen ok
- Power supply : cannot use the 12V provided by the LVDS cable. Need external 12V power supply
- Upcoming compatibility testings:
i). MHL (smartphone mirroring)
ii) 360 around view system (getting a volunteer to install a 360 around view system , or maybe a more advanced 3D 360 around view system)
iii) Apple TV
iv) other HDMI devices such as PS4, digita TV or any other HDMI device I have at home

Can you test Bluetooth audio syncing?

Also, how are you designing the Switch itself to function? I would recommend you implement something like this
DC3V 3.7V 5V 6V 7V 9V 12V Mini Relay Wireless Switch Remote Control Power LED La | eBay

Which could be programmed into the MCU homelink system to switch video inputs.

 

[Krash]

Please put a HomeLink receiver on it so it's possible to change the video feed between rear camera and hdmi video on the MCU screen

Maybe include a Homelink bridge to another Homelink broadcast station so Homelink would actually work. Grin. Seriously though, this was a clever idea.

Ok, so this would be a tethered mirroring connection where you'd have to run a cable from this device to your phone?

Some implementations do wireless mirroring.

This is super cool! Was hoping someone would figure out a way to do this.

A chromecast would work for mirroring an Android phone (sorry iOS)...
