4D 4.3” LCD CAPE – BEAGLE BONE BLACK

1. Description

2. Features

The 4D 4.3” LCD CAPE is a cape specifically designed

for the Beagle Bone Black (BBB), and provides a 4.3”

primary display for the BBB for direct user

interaction and information display.

•

4.3” TFT LCD CAPE for the Beagle Bone Black

Available in 2 models, Resistive Touch (4DCAPE-

43T) and Non-Touch (43CAPE-43)

•

7 push buttons including LEFT, RIGHT, UP, DOWN,

ENTER, RESET and POWER

Available in both touch (4DCAPE-43T) and non-

touch (4DCAPE-43).

•

2 LED Lights for Power and User

2x2 Jumper with shunts for EEPROM CAPE ID

selection

The 4DCAPE-43 is not compatible with the previous

Beagle Bone (Beagle Bone White), and can only be

used with the Beagle Bone Black.

•

Module dimensions: 120.4 x 80.0 x 24.8mm

Module dimensions with Beagle Bone Black

connected: Approx 120.4 x 80.0 x 32.0mm

The 4D 4.3” LCD CAPE features a 4.3” TFT LCD

480x272 resolution display.

•

4x 3.5mm Mounting holes

RoHS and CE Compliant.

The 4DCAPE-43 utilises the drivers developed for

the CircuitCo LCD4, however provides a different

form factor and pricing point to the LCD4.

The Beagle Bone Black connects directly to the back

of the 4DCAPE-43(T), and provides everything the

CAPE requires such as power and display signals.

The 4D 4.3” 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 (normally heartbeat).

Mounting of the 4DCAPE-43(T) is achieved with the

4x 3.5mm mounting holes present on the CAPE,

enabling standard M3 or #6-32 screws to fasten the

4DCAPE-43 as required.

utility is closed, it is available again under the

System – Administration menu.

3. Getting Started

8. Complete – the Angstrom desktop should be

displayed on the 4DCAPE-43(T) and is ready for

use, else Andoid etc.

Requirements

The 4D 4.3” LCD CAPE is designed to work with

existing software and drivers already developed for

the Beagle Bone Black.

For support of the BBB and various distributions,

please seek support from the respective websites

associated with the BBB itself or the distributions –

See Section 5.

The Requirements for use are:



4DCAPE-43 or 4DCAPE-43T Cape

Beagle Bone Black (BBB) with suitable

distribution loaded

5V DC Supply suitable for the Beagle Bone

Black, recommended 2A @ 5V.

A good place to start for information and support

regarding the BBB and various distributions

available, is www.beagleboard.org



This website details how to update your software

on the BBB to the current version of Angstrom

available for the BBB

A Stylus is recommended for accurate touch,

however is not required.

How to use the 4D 4.3” LCD CAPE

This website details how to update your software

on the BBB for the current version of Andoid.

http://downloads.ti.com/sitara_android/esd/TI_A

ndroid_DevKit/TI_Android_JB_4_2_2_DevKit_4_1_

1/index_FDS.html

The following steps should be all that is required in

order to use the 4DCAPE-43(T):

1. Connect the 4DCAPE-43(T) to the Beagle Bone

Black while the Beagle Bone Black is not

powered. Outline of the BBB is printed on the

back of the 4DCAPE-43(T) as a guide for

orientation.

2. If using with other capes, ensure the 4DCAPE-

43 is not conflicting pin wise to any other cape

installed.

For support regarding the 4DLCD-43(T) CAPE

hardware itself, please go to the 4D Systems

website and either contact Support directly, or use

the 4D Systems Forum. www.4dsystems.com.au

3. Ensure the DIP Switch on the CAPE is set to a

different EEPROM ID to any other capes.

4. Ensure your Beagle Bone Black is loaded with a

suitable Linux distribution which is compatible

with the existing CircuitCo LCD4 CAPE or 4D

Changing the brightness (Angstrom)

By default the backlight brightness of the 4D CAPE

4.3 is set to 50% with Angstrom distribution

(20.06.2013). It is possible to change the backlight

brightness as the backlight is PWM controlled.

Systems 4DCAPE-43(T)

– See Section 5.

Angstrom release 20.06.2013 or later is

recommended. Android 4.2.2 has also been

tested and functions correctly. Other

distributions may also be compatible with this

display.

Please note, these instructions may become

obsolete as new versions of Angstrom are released,

or if different distributions are used.

5. Connect a 5V Supply to the DC Jack of the

Beagle Bone Black. It is recommended to use a

2A supply to ensure sufficient supply.

One method is to SSH into the Beaglebone Black

from your PC, and set the backlight value that way.

Note this does not persist over restarts, so this

would need to be entered into a startup script if the

setting is required to be set each startup.

6. Once power is connected, something should be

displayed on the 4DCAPE-43(T) as it is booted.

Once booted, the system should automatically

log in (assuming Angstrom Linux distribution is

used), and the Touch Screen Calibration Utility

should load automatically. If using the 4DCAPE-

43 without touch, this can be exited and

ignored.

At the command prompt, type the following:

cd /sys/class/backlight/backlight.10/

echo 100 > brightness

7. Calibrate the 4DCAPE-43(T) using the utility by

following the on screen instructions. If the

Where 100 represents 100%, this can be changed

to any number from 0 to 100 as required.

Changing the brightness (Android)

4. EEPROM Details

Changing the brightness on Android is simple.

Navigate to the Settings menu, and to the Display

option, and then to Brightness. Slide the slider to

the desired position.

On the 4D 4.3” LCD CAPE there is an EEPROM which

is used to configure the Beagle Bone Black with the

appropriate configuration in order to use the Cape.

Depending if the board is a 4DCAPE-43 or a 4DCAPE-

43T the EEPROM contents will vary slightly.

Android Information

Please note: some EEPROM content refers to the

LCD4 which is made by CircuitCo. This is the case

due to how the BBB identifies the CAPE and what

drivers to apply to it. Since the 4DCAPE-43(T)

utilises the LCD4 drivers, this must be the case.

The 4DCAPE-43(T) is compatible with Android 4.2.2

and has been tested with an image from TI (see

section 3.2).

It has been noticed however that the EEPROM

Jumpers both need to be connected/closed

otherwise the CAPE may not be detected by the

Android OS.

4DCAPE-43 EEPROM

EEPROM Support: YES

Board Name: 4D 4.3 LCD CAPE - 4DCAPE-43

Manufacturer: 4D Systems

Calibrating resistive touch (Angstrom)

When a distribution is used for the first time with a

4DCAPE-43T, the default calibration application

that comes with the Angstrom distribution is

started automatically (Refer to section 3.2) on

startup of Angstrom. If the calibration is however

input incorrectly and it is required to be set again, a

file must be deleted manually in order to then

recalibrate the display.

4DCAPE-43T EEPROM

EEPROM Support: YES

Board Name: 4D 4.3 LCD CAPE - 4DCAPE-43T

Manufacturer: 4D Systems

Note, this may change as newer distributions of

Angstrom become available, or if different

distributions are used, so these instructions may

become obsolete or inaccurate.

One method is to SSH into the BBB using your PC,

navigate to the following folder and delete the

specified file.

/etc/pointercal.xinput

One this file has been deleted, the calibration utility

can be run again.

5. Software / Driver Disclaimer

4D Systems has developed this 4DCAPE-43(T) CAPE for the Beaglebone Black, and is based on hardware already

present in the market. 4D Systems does NOT support any software associated with the BBB nor software and

drivers associated with this CAPE. It is up to the user to determine which software is used on the BBB and which

distributions are used on the BBB, and therefore which are compatible with this CAPE.

4D Systems has been made aware that there may be touch related issues with the Angstrom Distribution

(Possibly others if based on the same issue source) of Linux, and the mouse may appear to ‘self touch’ or jump

around the screen on touch, or generally behave erratically. Since 4D Systems has not developed nor supports

anything to do with the software associated with this hardware, 4D Systems is unable to assist or offer support

regarding this matter. ** A Fixed Kernel is now available, 3.8.13-bone37 while solves this issue **

The Android distribution listed in this document does not feature this erratic touch behaviour and effectively

illustrates the issues are software or driver related, and not hardware.

If these issues are encountered, it is encouraged to try the Android distribution to verify it is not a hardware

issue. If the issue remains, please contact the 4D Systems Technical Support. If the issue is no longer present and

touch works correctly on Android, then please contact the beaglebone.org community.

The 4DCAPE-43(T) utilises drivers which have been written for other devices on the market and the hardware is

set up in a similar fashion. Drivers for the Circuitco LCD4 are utilised for this CAPE and therefore if fixes are made

to improve compatibility with the LCD4, they should also function correctly for the 4DCAPE-43(T).

4D Systems is not responsible for issues regarding software or drivers associated with the BBB and the

compatibility with this product. Only Community software support is allowed via resources at
