GPIO rotary volume

[Substring]

@dh04000 indeed, much easier. Can't say if it's python 3 or not, but it looks rather easy to setup

[dh04000]

Is there any hope of a gpio volume by button or rotary encoder in the future, or should I start working on a new plan for my arcade box? Do you know if usb volume controllers work on recalbox?

[Substring]

It's hard to tell. We just lack devices to test. Almost everything in recalbox is ready to handle it, except the gpio handling

Lacking devices to test, does that mean that you lack a rotary encoder to test? How much to the recalbox paypal would solve that? There's an issue withe the gpio handling? I thought recalbox could read gpio events already?

@dh04000 we don't have any rotary button such as yours we do handle gpio, hopefully lol

Post a link to the cheapest amazon listing for a compatible rotary encoder with free shipping in France (do you have Amazon PRIME?). I'll put the listing money in the Recalbox paypal after my next pay cycle.

It's not a question of price, but time (wire, code, test), finding something that fits the needs, being able to make a description of how the button works so that anyone can find a similar rortary button.

Let's take a shortcut : does it work like this

If so, that's as we would expect it and it is easy.

I offered money because it is what I can offer Recalbox. I can't code, so the only things I can offer is time, and money. Time is me finding this and trying to talk about a feature that users (like me) might enjoy to have. I'd be willing to test it as well, tell me when and I'll purchase myself a rotary encoder. Money being to purchase the parts needed to allow you and others to attempt to implement it. If I could code, I would do it myself and contribute the code, but I can't.

Anyhoo, the github code matches an Adafruit rotary encoder, and from what I can gleam from the data sheet (https://cdn-shop.adafruit.com/datasheets/pec11.pdf), that image you posted matches the functionality, where the button is a simple on/off mechanism, and the left and right turns are a series of A or B connections to the common ground (middle post), depending on which direction is turned.

Seems to be what you expect.

Well @supernature2k can handle this, just leave him some time. But it should work one way or another if it's just a pair of switches

Hello @dh04000
look this script : https://gist.github.com/savetheclocktower/9b5f67c20f6c04e65ed88f2e594d43c1
may be you can create same for recalbox .

[dh04000]

NECRO'ing because there was an update on this rotary script by the author.

One of the author's said," the only things that need to be adjusted in this to make it python 2 compatible is change line #1 from: #!/usr/bin/env python3 to: #!/usr/bin/env python2, and change line #25 from from queue import Queue to from multiprocessing import Queue".

Ok, simple enough, ha!

Does recalbox run system.d and allow scripts to be started at start up?

Thanks.

@dh04000
like this ? https://github.com/recalbox/recalbox-os/wiki/Add-your-own-startup-script-(EN)

@dh04000 I finally bought some rotary encoders, but had no time yet to work on that tbh

[dh04000]

The next time the raspberry pi zero-w is available on adafruit, I'm buying and the rotary encoder suggested on the scripts githib page. I'll test it when I get it and report back.

[dh04000]

@Substring @acris

Ordered my rotary encoder!

[dh04000]

Rotary encoder received. Will try it out this weekend with the python script + author's modifications provided by the github page.

@dh04000 sadly i'll be off on holidays till 16th of April, so you may feel drown in a void if you're facing problems ...

[dh04000]

@Substring I always feel like I'm drowning in the void. I'm a research scientist in real life. Poking holes in the darkness to reveal the light is what I do.

[Substring]

@dh04000 well hopefully the void shouldn't turn to a black hole neither, you may just lack a few changes required in the python scripts, but it should work.

One important thing i'm thinking of is the setting of the bounce time if the scripts are using the wiringPi library. The idea (wiringPi or not in fact) is to let a delay between 2 "clicks".

But I'm pretty confident, it should work.

I tried following the guide here (https://gist.github.com/savetheclocktower/9b5f67c20f6c04e65ed88f2e594d43c1#file-monitor-volume-L1), but recalbox's file system seems different to retropie's. Also, does recalbox have systemd? Here's my terminal output following the guide, so you see how I failed.

# mkdir ~/bin

# echo $PATH

/bin:/sbin:/usr/bin:/usr/sbin

-sh: /bin:/sbin:/usr/bin:/usr/sbin: No such file or directory

# nano ~/bin/monitor-volume

# chmod +x ~/bin/monitor-volume

# nano ~/monitor-volume.service

# monitor-volume

-sh: monitor-volume: command not found

-sh: -sh:: command not found

# nano ~/monitor-volume.service

# chmod +x ~/monitor-volume.service

mv ~/monitor-volume.service /etc/systemd/system

mv: can't rename '/recalbox/share/system/monitor-volume.service': No such file or directory

Maybe you can figure out whats wrong @Substring ? I'm sure its trivial.
