Hyperpixel 4.0" Portrait, Raspbian Stretch Lite

Support
2

There’s an alternate driver for the HyperPixel4 touchscreen which might help- details here- https://github.com/pimoroni/HyperPixel4TouchScreen/tree/master/driver

And also discussed at great length here: https://github.com/pimoroni/HyperPixel4TouchScreen/tree/master/driver

Granted this repository doesn’t tell you that you need to make build and make install to replace the hyperpixel4.dtbo with a modified one before using the rotation commands documented at the top. ( I need to fix that )

Edit: For clarity the rotation settings specified in the normal hyperpixel4.dts for the normal driver are just for 0 and 180 degrees landscape modes. It’s been a while, but I think I remember issues with portrait that the alt driver fixed.

Edit 2: for brevity:

wget https://github.com/pimoroni/HyperPixel4TouchScreen/releases/download/v1.0/hyperpixel4-goodix-dkms_1.0_all.deb
sudo dpkg -i hyperpixel4-goodix-dkms_1.0_all.deb
git clone https://github.com/pimoroni/HyperPixel4TouchScreen
cd HyperPixel4TouchScreen/driver
make build
sudo make install

And then in /boot/config.txt use:

  • dtoverlay=hyperpixel4:rotate_0 - Portrait, USB ports on top
  • dtoverlay=hyperpixel4:rotate_1 - Landscape, USB ports on left
  • dtoverlay=hyperpixel4:rotate_2 - Portrait, USB ports underneath
  • dtoverlay=hyperpixel4:rotate_3 - Landscape, USB ports on right

These all match the number you supply to display_lcd_rotate=.

Note: both Portrait orientations must have framebuffer_width=480 and framebuffer_height=800 specified instead of the defaults in /boot/config.txt.
