4D SYSTEMS 4DPi-35 Primary Display – Raspberry Pi Compatible

4DPi

-35

Primary Display

– Raspberry Pi

4. Connecting the Display to the Pi

Hardware Connection

The 4DPi-35 is easily connected to a Raspberry Pi,

by simply aligning the Female 26 way header with

the Raspberry PI’s Male 26 way header, and

connecting them together – ensuring the aligning

is correct and all pins are seated fully and correctly.

NOTE: The 4DPi-35 is supported only by the 26

way header, and therefore pressing on the touch

screen may result in the 4DPi-35 moving towards

the Raspberry Pi, and therefore the circuitry

touching the Raspberry Pi. This could result in

damage to either product if a short circuit were to

occur. It is therefore highly encouraged to mount

the display and attach the Pi to the mounted

display.

If development is desired on the bench prior to the

mounting of the display, please ensure some sort

of support is provided between the 4DPi-32 and

the Raspberry Pi so they do not touch

inadvertently.

Included in the box is a small double sided sticky

rubber pad. This is optional, however can be

placed on the top of the Ethernet connector of the

Raspberry Pi, to provide some support to the

display.

Software Download / Installation

4D Systems has prepared a custom DMA enabled

kernel for use with the Raspbian Operating

System, which is available for download as a single

Debian Package. This can be installed over your

existing Raspbian installation, or it can be applied

over a fresh image.

If you are starting from scratch, start from Step 1,

else skip to step 3 if you already have a Raspbian

Image and which to apply this kernel to that.

Please note, it is impossible for us to know what

you have done to your Raspbian image, if you are

not installing from scratch – so if you encounter

issues, please try and use a fresh image to

determine if possible modifications are conflicting

with our kernel release.

1) Download the latest Raspbian Image from the

Raspberry Pi website:

http://downloads.raspberrypi.org/raspbian_la

test

2) Load the Raspberry Pi image onto a SD card,

using the instructions provided on the

Raspberry Pi website for Linux, Mac or PC:

http://www.raspberrypi.org/documentation/i

nstallation/installing-images/README.md

3) Insert the SD card into the Raspberry PI. Do

not connect the 4DPi-35 yet. You will need an

external monitor / keyboard / network

connection, else simply a network connection

to the Pi and the rest can be done over an SSH

connection. Start up the Pi with at minimum

an Ethernet connection connected.

4) Either log into the Raspberry Pi from your

keyboard/monitor using the standard ‘pi’ and

‘raspberry’ credentials, else SSH into your

raspberry PI and log in via your SSH session.

5) Once logged into your Raspberry Pi, you will

need to download and install the kernel which

supports the 4DPi-35. To do this, enter the

following commands in terminal/shell/SSH to

download the kernel from the 4D Systems

Server:

For the A/B/A+/B+/Pi2 use:

# wget

http://www.4dsystems.com.au/downloads/4

DPi/All/4dpi-3x_4-1-10_v1.0.tar.gz

# tar -xzvf 4dpi-3x_4-1-10_v1.0.tar.gz

-C /

Ensure there are no spaces in the links above

if copying/pasting.

By default the package is configured for

Raspberry Pi2. To use the kernel on Raspberry

Pi1, modify the content of /boot/config.txt.

# nano /boot/config.txt

Find and modify the following line:

kernel=kernel7_hat.img
