Rotate Pimoroni Hyperpixel 90°
Display Rotation
First change display rotation in /boot/config.txt
display_rotate=1
Edit Hyperpixel touch driver
Then you need to edit the touch driver. Luckily it is a python script. I have the Information from here https://forums.pimoroni.com/t/hyper-pixel-rotate/5276/4. But the script has changed.
sudo nano /usr/bin/hyperpixel-touch
So here are my changes.
In the upper part Exchange 480 by 800 and viceversa:
(e.ABS_X, AbsInfo(value=0, min=0, max=480, fuzz=0, flat=0, resolution=1)),
(e.ABS_Y, AbsInfo(value=0, min=0, max=800, fuzz=0, flat=0, resolution=1)),
(e.ABS_MT_SLOT, AbsInfo(value=0, min=0, max=1, fuzz=0, flat=0, resolution=0)),
(e.ABS_MT_TRACKING_ID, AbsInfo(value=0, min=0, max=65535, fuzz=0, flat=0, resolution=0)),
(e.ABS_MT_POSITION_X, AbsInfo(value=0, min=0, max=480, fuzz=0, flat=0, resolution=0)),
(e.ABS_MT_POSITION_Y, AbsInfo(value=0, min=0, max=800, fuzz=0, flat=0, resolution=0)),
(e.ABS_Y, AbsInfo(value=0, min=0, max=800, fuzz=0, flat=0, resolution=1)),
(e.ABS_MT_SLOT, AbsInfo(value=0, min=0, max=1, fuzz=0, flat=0, resolution=0)),
(e.ABS_MT_TRACKING_ID, AbsInfo(value=0, min=0, max=65535, fuzz=0, flat=0, resolution=0)),
(e.ABS_MT_POSITION_X, AbsInfo(value=0, min=0, max=480, fuzz=0, flat=0, resolution=0)),
(e.ABS_MT_POSITION_Y, AbsInfo(value=0, min=0, max=800, fuzz=0, flat=0, resolution=0)),
and in the lower part Exchange x and y and add flipping the coordinates.
write_status(y1,800- x1, touch_one_start is not None, y2, 800-x2, touch_two_start is not None)
Restart hyperpixel touch daemon
sudo systemctl restart hyperpixel-touch
