Description: The 7.0” resistive touch LCD touch from 4D Systems is a cape specifically designed for the Beaglebone Black, and provides a 7.0” primary display for the BBB for direct user interaction and information display. The Beaglebone Black connects directly to the back of the LCD cape, and provides everything the cape requires such as power and display signals. 

The Beaglebone Black LCD cape features 7 push buttons below the screen, LEFT, RIGHT, UP, DOWN, ENTER, RESET and POWER, along with 2 LED’s to indicate Power and User Status. Mounting the cape is easy with the 4x 3.5mm mounting holes present on it, enabling standard M3 or #6-32 screws to fasten the the LCD cape as required. 
 
Note: This LCD is only compatible with the Beaglebone Black.
 
Features:
  • 7.0” TFT LCD CAPE for the Beaglebone Black
  • Resistive Touch Screen
  • 7 push buttons including LEFT, RIGHT, UP, DOWN, ENTER, RESET and POWER
  • 2 LED Lights for Power and User
  • 2x2 Jumper with shunts for EEPROM CAPE ID selection
  • Module dimensions: 179.9 x 114.9 x 19.5mm
  • Module dimensions with Beaglebone Black: Approx 179.9 x 114.9 x 25.7mm 
  • 4x 3.5mm Mounting holes

  • I don’t see this on the description above, so here is the resolution from the datasheet: 800x480.

  • I want to use this simultaneously with a raspberry pi and beaglebone black. So I could have them both connected at the same time and be able to choose which one I have on. Would that be possible, if so, what would be the necessary connections?

  • Has anyone gotten one of these to work??? I’m still not giving up just yet…

    • What’s not working? You checked the datasheet out, and the EEPROM jumper settings if you are trying to run Android? Go to the www.4dsystems.com.au website and go to the product page for the Cape, the datasheet above is out of date.

      • The EEPROM jumper settings aren’t the problem. I’m not getting the navigation bar so once I get into anything like settings (a few levels deep) there is no way to get back to the “Home” screen without a hard reset. It’s also VERY slow. If anyone can point me to someone who has android working on this like a real tablet… I’d appreciate it.

        • You are running Andrews version of Android it seems (http://icculus.org/~hendersa/android/) ?, which does not have the keys mapped for Android via a Key Layout file. This isn’t a problem with the display. The keys just haven’t been mapped on that version by Andrew. See something like this, however I personally haven’t mapped the keys (http://source.android.com/devices/tech/input/key-layout-files.html).

          If you use the TI version which is in the Datasheet from 4D, that one works great. Does depend if you are wanting Kernel 3.8 or 3.2 though, as the TI version is 3.2 and Andrews is 3.8. But hardware acceleration for graphics is only working on 3.2 so far I believe, so is actually quite a bit faster than the 3.8.

          • Is there a link to an .img file? or do I have to compile it??? This shouldn’t be so difficult…

            • http://downloads.ti.com/sitara_android/esd/TI_Android_DevKit/TI_Android_JB_4_2_2_DevKit_4_1_1/exports/TI_Android_JB_4.2.2_DevKit_4.1.1_beagleboneblack.tar.gz

              Instructions are inside. Its open source man, always expect to have to do some things yourself. The BBB is not a commercial product with commercial quality software, expect things to be a work in progress.

  • The one I have appears to work, but the mouse pointer just jitters around randomly in the bottom left corner when I’m not touching the screen (it follows my finger when I am). Is there something I need to configure, or do I have a faulty unit? (I reloaded the latest Angstrom onto it, just to be sure. Tried the calibration screen, it just got stuck while the pointer jittered around…)

    • Hi, yeah its a problem with the Kernel which has been acknowledged by the BBB community, and hopefully a fix is coming out soon. See this post, it has a bit about it: http://tinyurl.com/qzfxvm4

      and also this: http://tinyurl.com/nayalul

      You will notice if you load Android, the problem isn’t there.

    • I have the same issue. I am unable to use the touch screen. Plugging in a USB mouse stops the jitter. I contacted 4dsystems and was told it was an issue with the beaglebones and not the screens.

      • Touch issues solved with latest 3.8.13-bone37 kernel. Debian image with all fixes in place available from here. Works really well. http://rcn-ee.net/deb/testing/2014-01-29/

  • They don’t sell stands for the LCD capes. Why?

  • It strikes me that this might make a decent display for a DIY oscilloscope. 400 pixels vertical is ample, compared with most low-cost ‘scopes on the market, which are 8-bit precise in voltage. With the extra ~140 pixels, you could have some extra headroom for dual-trace, perhaps. But I don’t know yet how this screen is refreshed, and how fast. Is the entire display refreshed at regular intervals? Or, alternatively, does every pixel remain lit until it is individually addressed and turned off, the opposite for turning on a pixel? Any thoughts?

  • How is the LCD panel held in place? Double side tape?

  • Not mention above is the fact that this cape has pass-through sockets on the back so you can use other capes with it (depending on pin usage compatibility)
