New LCD device support: Samsung SPF Digital Photo Frames


Recommended Posts

I have a Samsung SPF87H frame that also only works for approximately 5 seconds. 

 

I'm running a clean install of Windows 8.1, with a registered copy of Aida 64 and the Samsung SPF drivers downloaded from this site.

 

Can you help get me running for more than 5 seconds? :-)

To all users of SPFs: I found the way how to control SPF brightness. I found the way how to switch back to storage mode after AIDA exit (however developer already knew it). I send this to developer

Would be great to add it next to the jpg 0-99 field ^^

Try to lower the compression setting even more, and see if it helps. As for the LibUsb drivers: you can only install them when the SPF device is in mini-monitor mode. Try to remove the Samsung drive

AIDA64 uses an unofficial, non-documented interface to communicate with Samsung SPF devices. If it doesn't work on your device, then I'm afraid we cannot help you out :( Only one thing you can try: in case you have a complicated LCD layout, you can try lowering the JPEG quality, but about the 5-seconds issue I don't think that would help :(

Hi thanks for your reply.  I have tried changing the quality to 50 %, I still only get a display for 5 seconds. 

 

Your reply does contradict the first post in this topic stating support for Samsung SPF frames in particular the model I managed to track down. Maybe this should be edited as I'm the second person to indicate problems with the SPF87H.

 

 

 

It now looks like I have to find an alternate display, can anyone recommend a USB display device that works ?  At the moment this is a disappointing outcome.

We've edited the first post, thank you.

How about using your cell phone or tablet display as a wireless LCD for AIDA64?

Thanks for replying Fiery.

 

I did briefly try using an old Ipod touch but couldn't connect to the IP address.

 

Ideally I would like a display big enough to show a number of sensors at the same time, that's why the photo frame option seems an ideal solution.

 

I would love to purchase a Samsung 800P but they seem impossible to track down in the UK.

 

 I'll keep looking. 

 

Final question, I was considering a Yocto Display, as an alternative.  Have you tested these displays and is it possible to have multiple pages as I'm not sure how much data could be displayed on the small screens?

We've tested the AIDA64 LCD module with Yocto-MiniDisplay and Yocto-MaxiDisplay, and they both worked flawlessly. But those are quite little screens, compared to a photo frame. And they do not feature buttons to change pages.

I try to use SPF-107H (LP10|PLERT/EN,  PID=$2036, VID=$04E8, firmware 1008) in Win7x64. It works only 2-3 seconds.

Do you use the Samsung Mini-Monitor driver, or our LibUsb driver?

Without installed "Frame manager" frame don't work at all. AIDA don't recognize it.

I can't install LibUsb driver - without "Frame manager" frame may be manually turned in "mini-monitor" mode for 2-3 seconds, after that it unconnect from USB.

For work I close "Frame manager" and start AIDA. It successfully turn frame from "storage" to "mini-monitor" and show picture, but only 2-3 sec. After that USB connection close.

Sad to hear that it doesn't work with either driver :( I've moved your device to the "not working" category in the opening post. I'm confused though, since it seems to work in some cases, while on a similar (or almost similar) device it fails to work. Maybe the issue is related to a certain hardware revision or firmware revision? Hard to tell, we have very limited knowledge about SPF variants :(

Maybe it will be helpful:

Controller of frame is MP630DTCG-B - http://www.modiotek.com.tw/index.php?option=com_content&view=article&id=62&Itemid=82〈=en
I try to use it in Windows similar to this projects:
http://web.media.mit.edu/~gracewoo/stuff/picframe/
http://www.puschmann.net/page/?page_id=62
But unsuccessfully.

 

Maybe this models (SPF-87H & SPF-107H) has "exit timer" and it close connection if frame frequency is very low.

I try to decrease LCD update time to 50ms (20Hz), but min in 5.20 version is 500ms. Can you expand this range to check it?

We've extended the update frequency down to 100 msec in the latest beta update to AIDA64 Extreme:

http://www.aida64.com/downloads/latesta64xebeta

But, I don't think it would help. Please let me know how it works.

I try both: LibUsb driver from post #38 and Original Samsung.

The same result.

Does the every 500ms there are "Device Vendor_Device" command - two zero bytes anomaly happen with both drivers?

My mistake - correct name of command is "Function Vendor_Device".

This command sending by "Frame manager" to 0 point. I try to do it from custom application and get good result - USB connection is stable. Also I try to increase frame update time to 500ms. Now "Function Vendor_Device" (two zero bytes to 0 point) and frames (packets to point â„–2) sending from one timer - 500ms. USB connection is stable and pictures shows correct.

I don't think I can follow that :( If by Frame manager you mean Samsung Frame Manager software, then you have to uninstall all SPF-related Samsung software and driver before installing our LibUsb driver. Otherwise Samsung's software and driver may collide with our driver.

But, in case you've figured it out and now things are stable, then it's great :)

Concerning the switch back from monitor mode after a couple of seconds for some Samsung SPF I have found on "http://pyframe.blogspot.de/2011_12_01_archive.html" this information (it's from a python script). 

  # This control function is required to keep the frame permanently in Mini Monitor mode. 

  # When the frame is switched to Mini Monitor mode, it remains there for a few seconds, but 

  # then switches back, unregistering from the USB bus.

  # This function is needed only once after connection of the frame, but it does not seem

  # to do any harm when transfered with every picture transfer

  dev.ctrl_transfer(0xc0, 4 )    

 

Perhaps you can add this byte sequence to the contol code sent to the frame, to solve the problem of the not permanent "mini monitor" mode.

That seems like a very useful information, thanks a lot! We've already implemented it in the latest AIDA64 Extreme beta update available at:

http://www.aida64.com/downloads/latesta64xebeta

Let us know if it helps to fix the disconnection issue.

If works for me (SPF 107H USB-ID 04e8:2035 / 2036).

Great (and unbelievable short time to make it happen)!

Your post came at just the right time to squeeze a new single line into the code before we rolled out the new beta update :) Thanks again ;)

      hi all, newbie here! this is my first post so i hope it has landed in the correct place..  be gentle!

      i have installed the 'simple' version of a64, is it possible to run multiple instances of the sensor panel? i have the sensor panel running in a 5 inch screen located inside my case but have a room change planned which will put the case high on a shelf out of my eye sight so i would like a second display for stats placed under my main monitor. i plan to use a larger screen say a 10.1 'ultrawide (if thats the correct term) as i like the extra real-estate. what are my options?
      on a similar topic, is it possible to create an 'unpublished' senor panel before removing the currently used panel? or would i have to save the current panel to file or something then start a new panel?
      also can anyone point me to gauge resources, ie pre made gauges? or an easy to understand tutorial for how to diy them? total novice here, but can follow an idiots guide!

      i have included the final evolution of my first attempt using the provided gauges etc, it took me ages to get rid of the green dials.. i finally gave up trying to figure it out in a64 so i just changed the hue on the 5inch monitor lol. really hoping to learn the skills to create something like i have seen on here.. some really nice work on the share your panel thread, some of those must have taken ages!!! impressive. 
      any advice greatly received, but remember your talking to an a64 absolute novice!!
      Thanks folks.

      Hey guys!
      Im hoping for some input regarding my question. I saw, AIDA64 is supporting a lot of different displays and interfaces. Now which one to choose? Heres some more input from me about what im looking for:
      [Mandatory] 5-8 inch LCD display [Mandatory] only USB powered [Mandatory] black frame design to match my case, if possible [Optional] A flat, not too thick one [Optional] small bezels if possible [Optional] No buttons neccessary, i want to place it inside of my case. [Optional] an internal USB connector to directly connect it to the motherboard At the moment im using some Aquacomputer Vision OLEDs which are working fine. But i can already see some burn in and they are pretty small. Since theres no LCD coming from Aquacomputer anytime soon, im thinking about using AIDA64 to get my data on screen. I have 3 of those OLED on each of the drive bay covers, this is more or less the space i have available
      I have attached a screenshot of the system with the OLEDs and their current placement for you to visualize.
       
      Thank you for your suggestions!

      Hey there,
      Installed the new card but i do not see all the sensors, like i did on my 2080 ti.
      Also, when the GPU is idle (low clock) the GPU Clock field on my sensor panel and LCD appear and disappear sometime. Also,
      app takes way longer to load.
      If any logs are needed just let me know.
      Cheers!

      Hey, new to Aida64 so be gentle,
      I have 2 Raspberry Pi 7" touchscreen display. One has a pi connected to it and the other is just the panel. The panel has just a usb port and a micro usb port. What's the easiest way to get this up and running as an external monitor? I've been running ModBros but I'm looking for something more customizable. 
       
      Also, other then the one forum post, is there anywhere to get templets to get a start from and build off of that?
