I finally got around to using the HyperPixel square touch for a cinipi project, and it doesn’t seem to do anything.
I’ve tried it witha pi 4, 4b+, 5 and zero.
It doesn’t even look like it’s turning on, no light or screen flashing, or really anything.
Hdmi on the pi’s work just fine.
I’m missing something on my end, or did I buy a dud?
Did you do the following?
If you’re using a recent version of Raspberry Pi OS (Bullseye or later) then you’ll need to use the built in kernel drivers - just add the following line to the end of your boot/firmware/config.txt (and then reboot):
dtoverlay=vc4-kms-dpi-hyperpixel4sq
You will need to have I2C disabled (sudo raspi-config nonint do_i2c 1) along with any other interfaces that use the GPIO.
Nope, still nothing. Also the cinipi V2 was made just for that screen, and it still did nothing.
I think this thing is dead.
