HyperPixel 4.0" Drivers

HyperPixel 4.0 is an 800x480 or 720x720 pixel display for the Raspberry Pi, with optional capacitive touchscreen.

Installing / Uninstalling

This repository contains several branches for different combinations of Pi and HyperPixel4 boards.

You should use our one-line installer to install HyperPixel4 Rectangular and Square:

curl -sSL https://get.pimoroni.com/hyperpixel4 | bash

When prompted, pick the combination of Pi and touchscreen that you're planning to use.

Note: A HyperPixel4 setup for Pi 3B+ or earlier will not readily work if you move it over to a Pi 4, you should run this installer again to update the drivers.

Manual Installation

Here's a list of active branches and which Pi/display combination they support:

• pi3 - Pi 3B+ and earlier, HyperPixel4 Rectangular
• pi4 - Pi 4, HyperPixel4 Rectangular, use hyperpixel4-rotate to rotate once installed
• square - Pi 3B+ and earlier, HyperPixel4 Square
• square-pi4 - Pi 4, HyperPixel4 Square

To clone a specific branch to your Pi, run:

git clone https://github.com/pimoroni/hyperpixel4 -b <branch name>

Then cd hyperpixel4 and run sudo ./install.sh to install it.

Rotation

Rotation on Pi 4

HyperPixel4 is a portait display, so on first boot it will start in portrait mode with the USB ports at the top.

On Pi 4 we can take advantage of the rotation available in Display Configuration, and provide you with a command for setting both display and touch rotation together.

To rotate HyperPixel4 on a Pi 4 use the hyperpixel4-rotate command.

Landscape mode, HDMI/power ports on the bottom:

hyperpixel4-rotate left

Landscape mode, HDMI/power ports on the top:

hyperpixel4-rotate right

Portrait mode, USB ports on the top:

hyperpixel4-rotate normal

Portrait mode, USB ports on the bottom:

hyperpixel4-rotate inverted

If you're running this command over SSH you should prefix it with DISPLAY=:0.0

180 Degree Rotation on Pi 3

Note: You must build the latest dtoverlay file to enable rotation support:

1. Go into src
2. run make to build a new hyperpixel4.dtbo with rotation support
3. copy the overlay with sudo cp hyperpixel4.dtbo /boot/overlays/

To rotate your HyperPixel4 you must edit /boot/config.txt and change the following lines:

1. Change dtoverlay=hyperpixel4 to dtoverlay=hyperpixel4:rotate
2. Change display_rotate=3 to display_rotate=1

This will rotate both the display and the touchscreen input to match.

If you're using a non-touchscreen HyperPixel4 you need only change display_rotate.
