Hello,
I’m wondering what the best option is nowadays for using the GPIO pins on a Raspberry Pi in Pure Data.
Wiring Pi seems to be no longer available, as far as I can tell. I’m not sure what other options there are?
One option suggested elsewhere for inputs was to use the “retrogame” script to turn GPIO pin activity into keyboard presses and use the [key] object in Pd, but I can’t seem to get that script to work properly yet.
Any suggestions would be great, thanks in advance.

Hello,
an alternative is about using a python script that communicate with PureData through OSC, it can be done with abstractions on pd side and examples provided by python users.
Best regards,

Use pd-l2ork. It comes with disis_gpio and disis_spi (for analog inputs, like the ones found on Lots-of-Pots shield) which should cover all your needs. It includes both hardware and software PWM, as well as all the usual I/O GPIO stuff.
Best,
Ico
Thanks all. I ended up going with Patrice’s solution, making a python script that accesses the GPIO pins and sends the data through OSC. I have no prior knowledge of Python so I had been avoiding this approach, but it turned out to be pretty straightforward.
If anyone now or in the future would like an extremely bare-bones but functional example that takes button inputs from Raspberry Pi GPIO pins and sends them to Pure Data, I’ve put a minimalist example up on my GitHub along with some documentation. This is primarily for my future self, but perhaps it will be of help to others: https://github.com/yannseznec/gpioOSCpd
