I have a Hyperpixel 4 touch on a Pi4b8Gb and i want to utilize a GPIO pin for the data stream to some Neopixel WS2812 LEDS, i’m sure i ve read one of the GPIO pins can be hijacked. Is it true, which pin would it be and how would i get access to it / program it?
Is there a better way i can do this, is there a USB to SPI I/O bard i could use? I have a seperate 5v10a PSU already.
Any help would be appreciated.
I don’t know if this will fully work for your needs but might be worth a look see.
It can also be done , as far as I know, on a Pi running PiOS.
If you have a spare Pi Zero kicking around you could have a go and see if you can get the control you need over a GPIO pin on the Zero.
