In case you want to modify something to DT you can modify dtc and make an object file from. More information take a look at this website: Īll the DT in BBB has a extension (dts for source file and dtbo for object file). Connecting to the BBB and downloading desire device tree.ĭevice Tree or (DT) is the data structure which pass all the hardware details to the OS in a boot time. There is a very good tutorial on how you can make the image on SD card in "getting started" section of BBB original Latest image you can get the latest image from here. As BBB tutorial website suggested it's better you upgrade it with VirtualBox and Debian, you can find many YouTube tutorial in internet.īeagle Bone Black ship withe Debian Wheezy 7.4.

for running Debian you need to have image of Debian for download it go to this websiteĪnd under title " netinst CD image (generally 150-280 MB)"Ĭhose "amd64" after download done, go to VirtualBox and install Debian on it. Installing Virtual Box and Debian.įor keep this tutorial as consistence as possible, use Debian on Virtual Box.Īs you know you can connect to your BBB with "ssh" command from Mac command line.ĭownload the latest version of the Virtual Box from Īnd install it. usually all the back light LED needs 18 or more voltage to find out this read LCD datasheet) This is the datasheet for my LCD (I used the LCD with built in Back light driver, you have to beware about back light on your LCD. Please beware about LCD DATA 10 ~13, since they aren't in a correct order.
Please connect the correspond LCD pins to BBB as follow.
LCD CAPE FOR BEAGLEBONE BLACK DRIVER SOFTWARE
These are my hardware and software configurations and you will have all this configuration byīBB OS: Debian Wheezy 7.8 Debian (BeagleBone, BeagleBone Black - 4GB SD) To get your graphical output on your LCD.
LCD CAPE FOR BEAGLEBONE BLACK DRIVER HOW TO
I will bring all the steps you need to connect the single LCD to your BBB and how to configure them See your BBB graphical output on LCD by connecting correspond pins on LCD and BBB if you don't use LCD Cape. Since few month ago that I'v starting working on a project which involve graphic LCD I foundįor connecting the BBB to LCD there is LCD capes.īecause some of these capes was discontinued and on the other hand they are little pricey, theyĪll the capes has a EEPROM which configure the kernel in a boot time. It's very interesting for me to bring all experiences in HMI design with micro-controller on I was made a lot of custom HMI with graphic LCD and the micro-controller like AVR and PIC. * BeagleBoard-DeviceTrees/v4.19.x-ti-overlays/src/arm/bbb-bone-buses.In this tutorial I'm going to show you how to setup and configure the LCD for BeagleBone Black. * BeagleBoard-DeviceTrees/v4.19.x-ti-overlays/src/arm/bbai-bone-buses.dtsi * See these files for the phandles (&bone_*) and other bone bus nodes B: We set pin multiplexing for pins on the Beaglebone blac expansion connector P9Įxpansion_connector_p8_pinss: expansion_connector_p8_pins /* BACKLIGHT */ A: We set pin multiplexing for pins on the Beaglebone blac expansion connector P8 I also used node port to connect it to the frame buffer device node fb. I also read official Linux devicetree "bindings" as indicated in the code's comments and I defined my LCD panel device node panel.
LCD CAPE FOR BEAGLEBONE BLACK DRIVER MANUAL
I was referencing AM335x's reference manual & datasheet to do this.
LCD CAPE FOR BEAGLEBONE BLACK DRIVER CODE
Then I created an overlay &am33xx_pinmux for proper pin muxing as can be seen from the code below. a/arch/arm/boot/dts/am335x-boneblack-common.dtsi I used this patch: diff -git a/arch/arm/boot/dts/am335x-boneblack-common.dtsi b/arch/arm/boot/dts/am335x-boneblack-common.dtsi I first made sure HDMI is not detected on the I2C. I am trying to connect my LCD panel ( datasheet) to the Beaglebone Black's (BBB) expansion connector P8/P9 ( BBB referencce manual, p.
