Re: [PD] Current best practice for GPIO pins on Raspberry Pi?
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 > On 8 Nov 2023, at 16:13, Patco wrote: > > 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, > > patco > >> Le 8 nov. 2023 à 15:14, Yann Seznec a écrit : >> >> 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.

Re: [PD] Current best practice for GPIO pins on Raspberry Pi?
Maybe not exactly what you need, outputs only: GPIO ASR If you need to drive GPIOs with soft PWMs for solenoids or the like, there is an Pd external for Debian Linux, Arm A20 processors, but should work on Raspberry Pis also, since it adds an linux kernel driver using libgpio. It can drive up to 140 GPIOs as PWMs on an Olimex A20. - https://git.iem.at/pd/gpioASR and needs a kerneldriver: - https://git.iem.at/ritsch/gpio-asr There was a plan to expand its functionality for standard GPIO use, also encoder for bldc motors, but... time flows by ... and no urgent need ... ;-). mfg winfried Am Mittwoch, 8.

Re: [PD] Current best practice for GPIO pins on Raspberry Pi?
My old 'gpio' object was from 2013. it just issued linux reads and writes to some device. I don't know if it would still work. I've stuck it on msp.ucsd.edu/tmp/gpio.c in case you get desperate enough to want to revive a 10-year-old bit of system hackery :) Miller On 11/8/23 19:07, Dan Wilcox wrote: I believe there was a basic [gpio] object, perhaps from Miller but I don't find it on his site now.

Re: [PD] Current best practice for GPIO pins on Raspberry Pi?
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.

Re: [PD] Current best practice for GPIO pins on Raspberry Pi?
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.
