Hello All,
I started building a Langstone during one of the lockdowns and it's been in the cupboard for a while. I've got it back on the workbench and updated the software (./stop, ./update, reboot) - it all works with the exception of the touchscreen portion Hyperpixel display, which was working fine before the update. Any idea why it might have stopped?

Hyperpixel 4 Touchscreen stopped working
Re: Hyperpixel 4 Touchscreen stopped working
Updating shouldn’t affect the touch screen.
It is possible the screen rotation has got changed.
Make sure there is a line ‘display_lcd_rotate=3‘ in /boot/config.txt.
You could also try running HW_test which should report any screen touches.

It might be something to do with the IO use. That screen is only supported by the Langstone, not the Portsdown, so it's not going to be a conflict with Dave's updates.

It certainly won’t work with Portsdown. The display uses most of the IO. Langstone disables its IO use when it detects the hyperpixel display.
The touchscreen uses I2C.

Well, I fired it up to start troubleshooting... and it just worked. No idea why it wasn't working before it seems to be ok now. Thanks all anyway!
