beaglebone lcd display factory

The BeagleBone LCD7 Cape provides an LCD solution with touchscreen capability for BeagleBone boards. The 7" TFT LCD screen, attached to the topside of the board, can display up to a resolution of 800x480 and is a 4-wire resistive touchscreen. The board is equipped with seven buttons located at finger-friendly positions. These buttons include power, reset, and five user buttons, which are mapped to different GPIO signals. The backside of the cape is where the BeagleBone and additional cape can be mounted.

In revision A3 the Enter button has been moved from GPIO3_19 to GPIO0_3 and LCD_DVDD_EN has moved from GPIO1_31 to GPIO0_2. These changes in GPIOs are to support awake interrupt in sleeping mode.

The latest revision A3 have 10 eMMC pins removed from the LCD7"s expansion connector. This removal is due to the fact that this LCD7 Cape was originally designed for the BeagleBone (White); thus, when using with BeagleBone Black, these eMMC signals are subjected to load and noises, creating problems with booting and using the eMMC.

We have been reported by a small number of users that their LCD7 Capes revision A3 have some issues with BeagleBone Black. These issues could be hanging during boot or crashing when accessing Angstrom system menu. The LCD7 Cape was originally designed for BeagleBone (White), which boots from SD card. When using with BeagleBone Black and booting from eMMC, the integrity of eMMC signals on some LCD7 Cape may be affected. If your LCD7 Cape have this issue, there are three work-arounds below:

Cut 10 eMMC pins on connector J1 of your LCD7 Cape: 3-6, 20-25. You can visit this link for which pins are eMMC signals. The photo on the right shows J1 connector after the eMMC pins are removed.

Instead of permanently removing the eMMC pins on your LCD7 Cape, you can also use one of these Cape expansion connectors between the BeagleBone Black and LCD7 Cape. By using this connector, you can remove its eMMCs instead of the ones on LCD7 Cape. The photo on the right shows the Cape expansion connector is used and its eMMC pins are removed instead of the ones on LCD7 Cape.

Compatible with BeagleBone Black using Angstrom release 2013-06-20 onward. However, only booting from SD card is supported. Note: Using Angstrom release earlier than 2013-06-20 on BeagleBone Black and LCD7 may DAMAGE your BeagleBone Black. Ensure you are using 2013-06-20 or later.

Compatible with BeagleBone Black using Angstrom release 2013-06-20 onward. Note: Using Angstrom release earlier than 2013-06-20 on BeagleBone Black and LCD7 may DAMAGE your BeagleBone Black. Ensure you are using 2013-06-20 or later.

Note: The Auto Calibration utility is automatically displayed when the card is used for the first time. This utility can be run again under menu System > Administration > Calibrate Touchsreen

NHD-7.0CTP-CAPE-N | BeagleBone Black Cape with TFT Display | 7.0" Sunlight Readable LCD | Capacitive Touchscreen | EEPROM with On-Board Dip Switches | Developing with Android & Linux

Engineered in Elgin IL USA, we designed this BeagleBone Cape to be a perfect fit for our 7.0” TFT displays and upgraded it with the sunlight readable NHD-7.0-800480EF-ASXN#-CTP display model. With capacitive 5-point multi-touch functionality and 800x480 resolution screen, this cape works seamlessly while developing with operating systems like Android and Linux. It includes an on-board dip switch for configuring EEPROM and secondary headers for additional cape connections. In addition to the secondary cape slot, we added four 3.5mm mounting holes that are compatible with standard M3 screws, a reset button, write protection pins, PWM backlight control, and an LED power indicator. With this cape we’ve made it easy to take your design process from concept to reality. When paired with the BeagleBone Black board (sold separately by beagleboard.org) you’ll have everything you need to plug-in and start developing.

Choose from a wide selection of interface options or talk to our experts to select the best one for your project. We can incorporate HDMI, USB, SPI, VGA and more into your display to achieve your design goals.

Equip your display with a custom cut cover glass to improve durability. Choose from a variety of cover glass thicknesses and get optical bonding to protect against moisture and debris.

Continuity loss? Used a multimeter to check connections to the FPC. All looks good, nothing strange. Somewhere in between this testing the LED backlight wasn"t lighting up when I connected the LCD. Whoops! I burn 4 LED drivers in the process (but they seem to have open LED "protection"?). Add a 16V Zener across the LED lines to prevent re-occurrence. The LEDs are in a 3-series (and currently unknown parallel lines) configuration and draw 9.5V.

Maybe some signal integrity issues? It"s Scope time.Put cape on the BBB, LCD disconnected. Probe signal pins. The highest frequency signal, PCLK (@30 MHz) appears clean enough. Data lines look good as well.

Look at the LCD panel under strong light. Was able to make out the Beagle on the screen, once again. The screen looks stable (a direct consequence of the fact that the signals look good on the scope).

Okay, now that we know the issue, we should need to just add some bypass caps to fix it? Sprinkle a few 10uF 0805 ceramic caps, one before the LED driver and the other across the LED driver output still the display appears to be as unstable as it was before.

At this point I asked in the HaD channel, and with feedback that maybe the onboard 3.3V of the BBB is not supplying enough current to power everything, try to power the entire cape with a 1117-3.3 fed from the 5V of the BBB. An unstable display, still.

I look at existing cape reference designs (CircuitCo BB-VIEW7 and 4DSystems 70T) and find that they power their LED drivers off the 5V rail, and not the 3V3 VDD rail. Maybe they knew something about ripple from LED drivers affecting the LCD supply?

This 7" touchscreen cape creates a fully integrated system when combined with your BeagleBone Black. Provides full Angstrom support for easy BeagleBone prototyping and projects. A secondary set of header pins gives built-in stacking cape-ability.

Awesome videos and very informational and helpful. I was on the raspberry pi, but i just got my beaglebone black yesterday. I was curious about a few things.

2.) out of the box, is I2C enabled? i have some project i want to port over to the BBB that is currently running on my pi (support for a 128×64 LCD display)

If you prefer Ubuntu, you can download Ubuntu from various sites, or get a pre-installed and configured micro SD Flash with Ubuntu 13.04 for the BeagleBone Black from:

Hi, if you are sure that the IP address is correct (e.g., 192.168.7.2) and the BeagleBone is not appearing as a USB device on your PC, then you should flash it again with a freshly downloaded image — it’s likely that the image on the eMMC is corrupt. Derek.

I have an application built with IAR that I am running from SD Card on the BeagleBone “White” board. I boot my application using an MLO file from the TI Starterware and create an “app” file to load which both live on the SD Card. As you know this setup will copy the application into RAM on the BB White and begin execution at 0x80000000. I use the tiimage utility to convert the IAR binary into an MLO loadable app file.

As of a couple months ago I started working with BeagleBone Black for a work project. Recently, I’ve written a bash script that is supposed to install the software I’ve written. Sometimes (not every time) after running echo -en ‘\n\niface eth0 inet dhcp\n’ >> /etc/network/interfaces; /etc/init.d/networking restart the board will stop responding…which doesn’t make sense. Other times it goes through the entire script without issue, and after a reboot it will no longer respond….but sometimes it appears to work just fine.

I’ve followed instructions from many different websites, but I can’t seem to get the BealgeBone Black (Rev B6) to load an image off the SD card. I’ve tried FAT16/FAT32 formatting on the 16GB SD card, used the latest Debian image from beaglebone website, and other combinations of stuff, trying to figure out how to get it to work. Sometimes when I hold the s2 / boot button, D4 will stay lit for most of the time, instead of D3…other times it’s reversed. Sometimes when trying, after waiting 30 mins, it appears to be finished by lighting up D3 and D4 solid, and no flash from the other 2.

I am trying to install ubuntu in beaglebone but ubuntu desktop environment wont’s came.Now i am trying to restore angstrom to eMMC on Beaglebone Black. I searched all things related to this but nothing found .please hlp me .

Frank, if you don’t need anything on the beaglebone then you should be able to reflash it using the usual steps. The alternative is to boot the BBB from a SD card (not flashing image) and then mount the FAT partition of the eMMC as a device. You can then edit the uEnv.txt file using an editor like nano. Hope that helps, Derek.

Derek, thanks a lot. I will try it. My objective is to stop booting at uboot. So that I can setup nfs and tftpboot. Since I messed up uEnv.txt Do you think I have to reflash it first? I was thinking it should at least try to boot and stop on uboot but not load kernel. That is why I modified uEnv.txt in first place. I am new to Beaglebone it is different than OMAP 3530.

Please help me because i want to restore angstrom os in eMMC in Beaglebone black. I was formatted my beaglebone because i want to restore anstrong os . When i am connecting beaglebone with my system then nothing is shown .I am not getting any solution how my beaglebone is working.plz Derek help me . ..plz

I did a procedure with beagleboneblack-save-emmc, but after a long time (with press the boot switch S2), nothing happen, the leds are OFF. no blink or anything.

I solved that problem. I downloaded emmc flasher from here http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBB_Rev_C_.284GB_eMMC.29. After that everything went as you stated. Thanks.

I hope this was not already posted, but I thought it was worth mentioning. The LED flashing sequence I saw when updating my eMMC was a back-and-forth (cylon eyes, KITT) pattern, and D5 did not stay on at all. My little HDMI display showed activity during the process before going all white, not sure why. When the process was done, all 4 of the LEDs when on, but they did not stay on longer than maybe a minute or two before all going dark. ?? The flashing worked though.

Hi there — try again, but make sure that if you have a REV-B BeagleBone that you use the 2GB flasher image, not the more common 4GB flasher image. Kind regards, Derek.

I have a BeagleBone and I did write an Angstrom image on provided sd card. Later when I connect it to my PC it’s not getting detected. The led’s are not glowing. Please help me. What should I do??

I believe I’m being a little rude in the above, but I’ve been scouring hundreds of articles for weeks now, all I want to do is update to the latest jessie images. Despite following vaguely written articles that point every which way to more vague articles, nothing works the way it’s should. If the BeagleBone was upfront and said “Hey, this is a really small project and is intended for people very familiar with a Linux Operating System” then I wouldn’t be as upset.

However that’s not the case. The BeagleBone was supposed to be “as easy as Pi” referencing the more widely supported Raspberry Pi project of which I am more familiar (but still nowhere near expert).

Exploring BeagleBone came yesterday and I found the info on page 90. Somehow I missed that on the on-line copy. I do better looking a a book than a monitor.

I have flashed the 3.8.13 bone79 on my BBB but now my 4D Systems 4DCAPE won’t show the IDE but does show a cursor arrow. Do you how I might get the display showing the IDE again? It did show the IDE before i upgraded to 79. I wanted to do the upgrade in hopes that I could get the BBIO ADC to work.

2) Then I booted up that version of Debian and logged on as root (w/o SD card in BBB). From here you can change the /boot/uENV.txt file as stated by: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBB_Rev_C_.284GB_eMMC.29.

Secondly, do you know of a definitive tutorial for QNX on Beaglebone? I’m thinking of using it for my final year project and really need a good introductory tutorial.

I am working on beaglebone where i have to log real time data which requires me to log the terminal output onto the SD Card of Beaglebone. When i plug in the Beaglebone, it doesn’t display the external storage. I have tried mounting it but in vain. I have created a log file in Cloud9 IDE. How do i export it to the external storage ?

I am trying to flash my beaglebone black board with a kernel that I build by following : “https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSDcard”. As I try to flash the board it seems to be writing the eMMC and says to restart the board after the process is finished. I remove the card and restart it, them after a while it shows the following message and does nothing.

I use BeagleBone black REVC with 4Gb eMMC memory. I followed above steps, and I wait over 1 hour, just USR0 LED and USR2 led still blink. USR0 led blink in beathearth pattern. I use USB as power supply. I can’t figure out what’s problem?

Green LCD Cape with Resistive Touch is designed for SeeedStudio Beagle bone® Green or Beagle bone Black with a compact 5-inch LCD which is smaller than a 7-inch one but provides a resolution of 800x480 using a layer of 4-wired resistive touchscreen for user interactions. It"s easy to setup by just connecting 2x46 pin headers to SeeedStudioBeaglebone®Green/Beaglebone®Black, which provides everything the cape requires such power supply and display signals. In addition, the cape can be powered by the built-in micro USB on the back. Buttons below the screen, LEFT, RIGHT, UP, DOWN and ENTER, provide an alternative way to interact with your screen. Two LEDs are used for power and user status indication.
