Pi3B+ and Hyperpixel 4 rotated - is this supported?

I’ve been trying to get the Hyperpixel 4 in Landscape working on a pi3b+ for 2 days now.

I’ve worked through;

:warning: PSA: Make sure you disable i2c, SPI and any other interfaces since the…se will cause a conflict in device-tree with HyperPixel :warning: :warning: A fresh image is recommended, but otherwise make sure you also disable the `hyperpixel4-init` system service! :warning: Pi 3B and Pi 4 users running the latest and greatest Raspberry Pi OS should forego our installer and use the instructions below. > :information_source: If you're tied to an older OS and you want to install the legacy drivers, use: > `curl -sSL get.pimoroni.com/hyperpixel4-legacy | bash` This new OS can currently be found in Raspberry Pi Imager under "Raspberry Pi OS (Other)" ![image](https://user-images.githubusercontent.com/1746967/162789702-0c95f165-e482-4d47-a179-d841b903985c.png) Once installed you need only one line in `/boot/config.txt`: * Rectangular: `dtoverlay=vc4-kms-dpi-hyperpixel4` * Square: `dtoverlay=vc4-kms-dpi-hyperpixel4sq` You can rotate these in config.txt by adding the `rotate=` parameter, like so: ``` dtoverlay=vc4-kms-dpi-hyperpixel4sq,rotate=90 ``` This supports rotation in console, too, for all you CyberDeck builders! ## HyperPixel 4 Rectangular Rotations Ensure rotation is set to "Normal" in "Display Configuration" And that the dtoverlay is in `/boot/config.txt`: ``` dtoverlay=vc4-kms-dpi-hyperpixel4 ``` Finally use one of the following `dtparam` lines immediately underneath to set the parameters: * The default is portrait with header on the right, no extra line needed * `dtparam=rotate=90,touchscreen-swapped-x-y,touchscreen-inverted-y` - Landscape with header on the bottom * `dtparam=rotate=180` - Portrait with header on the left * `dtparam=rotate=270,touchscreen-swapped-x-y,touchscreen-inverted-x` - Landscape with header on the top ## HyperPixel 4 Square Rotations HyperPixel 4 Square does not correctly swap or invert touch input, so you may want to use the Xorg config method below. Ensure rotation is set to "Normal" in "Display Configuration" And that the dtoverlay is in `/boot/config.txt`: ``` dtoverlay=vc4-kms-dpi-hyperpixel4sq ``` Finally use one of the following `dtparam` lines immediately underneath to set the parameters: * Default is header on the top * `dtparam=rotate=90` - Header is on the left (wonky touch, see below) * `dtparam=rotate=180` - Header *still* on the top (doesn't work? Same as default) * `dtparam=rotate=270` - Header is on the right (wonky touch, see below) :warning: The `touchscreen-swapped-x-y` parameter does not seem to work with Square. You may need to use the script below for Raspberry Pi OS with Desktop. ## On the fly rotation Rotating the display via "Screen Configuration" ("arandr") results in inverted touch input and other weirdness- use the dtoverlay params. If you want to rotate on the fly you can use the below bash script to rotate either display and persist settings into Xorg configuration files. :warning: Note: You *must* remove the `rotate=` argument from `/boot/config.txt` for these to make sense. You can remove the rotation config by deleting the `/usr/share/X11/xorg.conf.d/88-hyperpixel4-touch.conf` and `/usr/share/X11/xorg.conf.d/88-dsi-1-rotate.conf` files. ```bash #!/bin/bash UTILITY="hyperpixel4-rotate (Rectangular)" XORG_TOUCH_CONF_FILE="/usr/share/X11/xorg.conf.d/88-hyperpixel4-touch.conf" XORG_CONF_FILE="/usr/share/X11/xorg.conf.d/88-dsi-1-rotate.conf" OVERLAY_S="vc4-kms-dpi-hyperpixel4sq" OVERLAY_R="vc4-kms-dpi-hyperpixel4" function success() { echo -e "$(tput setaf 2)$1$(tput sgr0)" } function inform() { echo -e "$(tput setaf 6)$1$(tput sgr0)" } function warning() { echo -e "$(tput setaf 1)$1$(tput sgr0)" } function set_xorg_conf { if [ "$DISPLAY" == "" ]; then inform "No DISPLAY variable set, trying :0.0" export DISPLAY=:0.0 fi inform "Rotating display $1"; xrandr --output DPI-1 --rotate $1 MATRIX="$2 $3 $4 $5 $6 $7 $8 $9 ${10}" inform "Setting libinput Calibration Matrix: 1 0 0 0 1 0"; xinput set-prop "pointer:$DEVICE" "libinput Calibration Matrix" 1 0 0 0 1 0 0 0 1 inform "Setting Coordinate Transformation Matrix: $MATRIX"; xinput set-prop "pointer:$DEVICE" "Coordinate Transformation Matrix" $MATRIX inform "Saving xorg touch config to $XORG_TOUCH_CONF_FILE"; sudo tee $XORG_TOUCH_CONF_FILE > /dev/null <<EOF # Auto generated by $UTILITY, edit with care!

NOT WORKING ON RPI 3B+ despite the many "fixes"

It shouldn't be this hard to get a ~50 GBP monitor to work... I have tried t…he solution mentioned in #177, but still not working. I do get an image though, however it's stuck in portrait mode. And the touch is working if I want to click anywhere else but where I want. So it's not a complete waste of money, as long as I don't expect it to work the way it should.. 👍 I see that other people have a similar issue with no responses (#183 and #181 ) and no solutions, so here's to hoping the money goes to some sort of development 🥇

A few youtube tutorials - and got nowhere.

Is this supported use? or has the screen been deprecated?
