I received the adapter and an LG E980 panel. I have not been able to see any picture on the panel yet after connecting the panel to adapter board and connecting the adapter board to an USB host for power and debug.

I connected to the debug serial port and was able to navigate the menu to select the E980 panel and then to save and restart the adapter - it initially had the iPhone 4 display selected on the first power up. Even after selecting the E980 panel and waiting for the adapter to reinitialize, I don't see any picture on the panel. I am able to adjust the backlight brightness through one of the menu item but no picture so far. I was expecting at least a "NO HDMI" image but I see only either a black frame or occasional vertical or horizontal strips or lines when I connect the adapter to an HDMI source. With a PC as an HDMI source, I can see the detected available resolution is 1080x1920 as expected. I have several pieces of the adapter board and E980 panels just in case I may have done something wrong to the first setup.

I would appreciate any insight. Thank you in advance.

I've tested a 2nd setup with another adapter and E980 panel but the symptoms remain the same.

Finally got my setups to work (adapters + E980 panels). First two panels were defective.

if there any way of getting these in india??

Got mine from creotech.  It's got the e980 flashed preloaded.  But it's only doing portrait 1080x1920 native.  I can't get the HDMI to work with a blueray player or the pi.  I got it to work with a meego stick.  Any ideas on how to get the resolution to 1920x1080 for other inpit devices?  Check the YouTube link i posted about it. 

Hi,

The device can only do portrait (1080x1920) because smartphone LCDs only support portrait mode. There's no way to force an E980 LCD to scan in another direction :/

An alternative would be to use the DDR framebuffer to implement rotation. I didn't plan it since it makes the device useless for VR applications it was primarily foreseen for (rotation introduces one-frame delay). If someone writes a video rotator core, I'd be glad to add this feature.

Concerning RPi - you need to edit the config file. I'm preparing an official user's manual that will explain this stuff. To set up the pi, you need to edit the 'config.txt' file on the SD card:

hdmi_timings=1080 1 46 1 45 1920 1 10 1 4 0 0 0 48 0 108330000 1
display_rotate=1
framebuffer_width=1920
framebuffer_height=1080

Cheers,

Tom

Thanks twl for the project and for replying to this so fast.

I guess I'm still having a hard time understanding why you can't switch rows and columns on a dumb panel.  I'm going to do some reading up on LCD panels and why this happens for my own curiosity.
I've been looking too for a rotator, I looked into the minispartan6+ for this but I'm not well versed in code and frame buffering.
I thought it was merely changing lanes or writing in the code that height is 1080 and width is 1920 to get landscape mode.  I wish they made panels in landscape too.
Does this mean that tablet displays like a Samsung Galaxy tab are landscape since it appears they were meant for landscape?

Hi Tom, do you think it may be possible for this to be a future update for the firmware, or does this require a hardware-based solution? I'm looking to use the E980 display for a HMD. Alternatively, I may want to use it for a field monitor. In both of these cases I'm not using something like a Raspberry Pi which can handle the rotation at the source of the video.

Your post gives me hope that my setup can eventually work. I also got adapters from Creotech and E980 panels separately but for now cannot see any pictures on the screen (my posts are on 2/24/2016).

When you say "got the E980 flashed preloaded", I presume you mean the adapter FPGA bitfile programming. Was it something you had to do? Or did you mean you had it configured that way as it come from Creotech? I would appreciate any tips you have on getting your setup to work. Thank you for posting a video too.

Hi Thomas,

Could you send me detailed photos of the LCDs you've bought and the way you connect them to the PCB?

Tom

Hi Tom,

Thank you for responding to these messages and offering to help (I can't reply to your reply - seems like the levels of messages and replies are limited to three).

I finally managed to get multiple setups to work (adapters + E980 panels).

Over the weekend, I figured out that the initial few LCD panels that I was testing with adapters were, disappointingly, defective. With good working panels, I can now see video on screen through the adapters. Thank you again for making this project available.

1080x1920x48Hz is working great. From reading the project notes, I understand that for 1080x1920x60Hz the 64-pin Analog Devices ADV7611 chip is required. Looking at the board Rev 1.1 schematics and PCB layout available in the project repository on Github, I see that this chip used to be part of the design (or was planned?). On the current Rev 2.2 board I see a 32-pin TI TVP5150AM1 chip for analog to digital video input instead.

Does the Rev 2.2 board support only 48Hz at 1080x1920 due to the direct connection to the FPGA?

please let us know about the project

Has anyone tried this with the PS Vita Slim screen? Considering screens for a project and a replacement Vita screen has better specs than the arduino project screens. 

Hard to tell if this thing is still on, etc.

The idea of 4k projector from smartphone salvaging is tempting inthe context of current pricing...

This particular project however comes short of the 4k screens because the mipi dsi controller goes full hd but not 4k or higher(Its under features)

Toshiba makes a 4k hdmi 1.4a to mipi dsi chip called TC358870XBG. They also boast that the chip is used by Oculus rift hardware.

http://toshiba.semicon-storage.com/info/lookup.jsp?pid=TC358870XBG&lang=en_us®ion=ncsa

Would be good to know how latency plays into all this, i.e. The Toshiba vs this hackaday.io project speed test, reliability etc.

P.S. I really like the thinking behind going for custom ASIC designs.

Would be great to just give ourself the stuff thats lacking ... Like hdmi 2.0 to mipi dsi/lvds and the 4k super mhl to mipi dsi/lvds or whatever they use to drive 4k and above

Great project! Any plans to make a 4k compatible ASIC ? Xperia Z Premium might be used to make a nice 'affordable' 4k projector!  

Very interesting project, I would like to order two pcs but Creotech is not responding :( Is is possible to place an order somewhere else?

Would it be possible to provide a working bitfile for the rev 1.1 board and iphone4 display e.g. on github?

Do you think that if we all pitch in, we could raise $22k for a custom ASIC?

If there's 400 people buying it (estimated from 376 on the poll http://doodle.com/poll/uv283rp366prppnt), that's a unit cost of $55 USD. That's more than the $20 FPGA, but power consumption would be lower and physical size would be smaller. 

It would also be so satisfying to see the amateur community finally reaching silicon. 

will this adapt to the iPhone 6 plus displays ?

For those interested in D-PHY DSI check the "DSI Transmit Bridge" Complete HDL Reference Design from Lattice. Works with MachXO3 FPGA. On DigiKey or Mouser there is a breakout board with MachXO3 for around 25 USD only. I'm not working for Lattice but their new MachXO3 FPGA looks interesting.

The project sources does not compile (in Xilinx). It is missing the dsi_pll_spartan6 Verilog file.

     This is all great stuff! I've been watching this project for what seems like all year and even though I've searched around and have found alternatives there's nothing that can compare to this.

     A lingering question I still have is will any work be done to make a case available for the screen and board? If a case can be made and sold seperately to make this look like a smartphone or a mini monitor that works as a mini high definition HDMI display. That would add additional appeal people like me that aren't interested in creating a custom case to house this hardware. 

    I plan on buying this either way, I've been anticipating it for so long that won't affect my final decision. I would definitely shell out extra $$ for a hassle free way to house this though :).

I need to stream video to a flexible display to make VR environment for an animal behavior study. Would your project work with flexible displays found on smartphones? 

i want to use the Creotech manufacture board for a 800x600 resolution 60 fps lcd, how can i configure those parameters?  

I am ready to buy your board in quantity ? What is the current outlook for purchase?

i am looking for PS4 hdmi direct connection to a smartphone display.. the CMOAR people need this too

Do you know that the note 4 uses MIPI as well?

can your send me  dsi_pll_spartan6.v file ? my email:  iamacoder@outlook.com

thank your very much!
