Hynix LED display and programmable storage chips

[johnzbesko]

I received a marketing flat screen "tablet" that, when opened (magnetic switch) automatically starts a video presentation (sort of like those birthday cards that, when opened, play a tune.)

I would like to use the LED in an Arduino application, but I don't know how to salvage/use the parts. The three visible chips have numbers:

H27U1G8F2BTR
HY5DU561G22FTP (maybe HY5DU561622FTP)
FK30GMP 24C

The USB cable connection simply charges the battery. lsusb does not detect anything.

Attached is a picture. I'm hoping someone can direct me. Google is not helping very much with anything I understand.

Thanks!

Damn, can't seem to attach 1.6Mb jpg image.

I would always advise using the parts in the present assembly. All the promo materials of this sort I have so far can indeed be upgraded via USB. At least you are using a suitable O/S.

When you figure out (checked the instructions?) how to post that picture we may have some better suggestions.

[johnzbesko]

Trying again with the 1.6MB jpg image. Here's the error message I get:

Your attachment has failed security checks and cannot be uploaded. Please consult the forum administrator.

Hmmm...

Allowed file types: doc, gif, jpg, mpg, pdf, png, txt, zip, c, h, cpp, ino, pde
Restrictions: maximum total size 2 MB, maximum individual size 2 MB

So it should be ok at 1.6MB.

Is the file type definitely ".jpg" rather than ".JPG" or ".jpeg"?

Try a smaller version.

[PaulRB]

Oh. Is it that you are not allowed to attach files until you have reached a certain number of forum posts?

[johnzbesko]

So, any other method to display a picture of the board to the fine readers of this forum?

[Grumpy_Mike]

Try and convert it to a .png image.

[johnzbesko]

As a .png

And so everyone does not have to download the picture:-

image guide will tell you how to post an image in a post once it is an attachment.

[Grumpy_Mike]

The H27U1G8F2BTR is flash memory, this is where the video is probably stored along with the program to play it.

Unfortunately I can't see anything you could possibly salvage unless you have a desoldering station and way of mounting the chips in an other circuit. They are very fine pitched ICs and not easy to work with.

Start by verifying how many USB wires actually go to the PCB. If it is four, then it likely would be able to access it.

[johnzbesko]

Yes, there are 4 wires to the USB port, but lsusb does not seem to recognize it. Maybe the USB detection on my Kubuntu 16.04 PC is deficient?

I was wondering if the LED ribbon cable could be used with another connector. Maybe I should post in a Raspberry forum?

Well, I hope you didn't buy anything from them. What a shocking waste to send such complex electronics out as a maketing stunt! If they can afford to do that, what must the markup levels be on their products?

[johnzbesko]

I agree, and it was shipped from London to Chicago express. Three people in my group received one. Now I have all three and wish to reuse them.

Any ideas, tips, suggestions?

[PaulRB]

If lsusb does not pick anything up, perhaps the usb cable is just for power.

Sorry, I don't have any other suggestions.

[johnzbesko]

Well, the problem is USB detection on my Kubuntu 16.04 PC. When I plugged it into a Win10 laptop, it detected a USB storage device with a video directory, with a video file within. I was able to replace the marketing video with a Three Stooges short and now it plays that.

However, I still want to use the LED for an Arduino or Raspberry project. Not quite sure how to proceed.

Thought as much, just an oddity of Ubuntu finding the driver details.

Use the device as it is. Perhaps plug it in to a Pi as a slave.

Get a display - with a driver - that can be used with an Arduino or Raspberry project. Simple as that.

I have the simil board

[amolina]

I connect to USB, and start to load the battery, the USB driver NO is valid, pass time and open the screen (magnetic) the screen chan to USB Pendrive and now can see like USB PENDRIVE en windows 7

and the disk is 97Mb

an use this List VolumeConfiguration.plist -> http://www.apple.com/DTDs/PropertyList-1.0.dtd">
in the Spotlight-V100 Directory like the CHIP V100
