It looks like you've got a mix of old and new settings in your `/boot/config.txt`- The non-fix settings are: ``` dtoverlay=hyperpixel4 dtparam=touchscreen-swapped-x-y=1 dtparam=touchscreen-inverted-x=1 ``` You need to remove these and,...

> There is also flickering and ghosting when connected to 0x5d as you can see in this short video of the display: https://www.dropbox.com/s/y98anzsv20uu9a4/IMG_3753.MOV?dl=0 I've just seen this flickering on a...

Run the command `hyperpixel4-rotate left` or `hyperpixel4-rotate right` to rotate screen and touch. It's actually a portrait screen but the Pi4-native commands to rotate it don't work until it's installed/rebooted,...

FWIW (and I know I'm a day late and a dollar short here) those are - indeed - I2C and SPI busses. All logic levels on the Pi are necessarily...

It mostly involves removing `dtoverlay=hyperpixel4` from `/boot/config.txt`, but there are also other lines that might look something like this: ``` dtoverlay=hyperpixel4 enable_dpi_lcd=1 dpi_group=2 dpi_mode=87 dpi_output_format=0x7f216 dpi_timings=480 0 10 16 59...

I guess this happens because `raspistill` draws directly into the framebuffer, ignoring the rotated, composited desktop produced by X. It's not something I can fix. And it's not really even...

The rotate script hooks into the Screen Configuration utility which uses a somewhat arcane method of persisting rotation settings across boots - it will write a file out to `/usr/share/dispsetup.sh`...

Any reason why would you remove the pin versus soldering wires directly to the underside of the pin header? The 5V pins are tied together on the board, so you...

Looks like I need to investigate the underlying xrandr commands to achieve rotation and set up some kind of launch script for usage where a standard Raspberry Pi OS setup...
