GPIO rotary volume

Ok, I can report that the script runs and works perfectly! I made the two modifications as the original author suggested to switch line 1 to "!/usr/bin/env python2" and to switch line 25 to "from multiprocessing import Queue".

But I have to start the script manually, "./volume-monitor.py" since it doesn't startup with the system. So, IF that was fixed then this would be working perfectly!

@dh04000 hi
The easy way to start it is to touch ~/custom.sh && chmod u+x ~/custom.sh and then edit ~/custom.sh to start your python

@Substring

So lets assume I have no idea what to add to custom.sh to start up my script. How do I do that?

[Substring]

@dh04000 just add what you'd usually tyoe on the command line say python /path/to/script.py

[dh04000]

@Substring Oh, that seems simple. Thank you.

I'l try it sometime this week/weekend and report how it went.

[Substring]

@dh04000 yeah we made it simple.for users with minimum bash knowledge to add a custom startup script, hence the custom.sh in the home folder

[dh04000]

@Substring @acris

Complete success! The script starts up with the system now! Thanks for the help!

@dh04000
good news , may be to make a complete tutorial ? please

[dh04000]

@acris

Ok. What form should it be in? A google document, typed into this forum thread, a new forum thread, something else?

Also, how do I do those cool code windows?

@dh04000 @acris the articld could be written directly in the wiki?
https://github.com/recalbox/recalbox-os/wiki/Mini-How-To-(EN)

[acris]

In the wiki

[dh04000]

@acris I'm still interested in writing a how-to use this script, but I don't know how to write to the wiki. Can I just send someone a google document with the how-to in it?

EDIT: Also @Substring once I wrote the how-to, would you mind checking it with your system since you also have a rotary encoder?

[acris]

No problem make google docs and a modo add your document on wiki.

[Substring]

@dh04000 mine is not plugged hahaha

the wiki syntax is farily simple, you even have a WYSIWYG bar to edit

[dh04000]

Done: https://docs.google.com/document/d/15gvyNhxF_knimoVxYE0X3E4Fe1n_DSU06Wli_QtnwxE/pub

@Substring @acris @lackyluuk It needs some minor editing work for the wiki. I put comments in blue on what needs to be done.

[dh04000]

I started editing the wiki, but I'm not good at it.... Also, please test those copy/paste instructions. I haven't had a chance to try it on my machine yet.

[acris]

Great !!! thanks a lot @dh04000

[dh04000]

@acris It's not done. I don't know how to add the text box with the script. Also, I want to show how to increase the rate of volume change, and change min and max of the script in the tweaks section. Which I still have to write. Got to test it on my machine first. Also, I need someone to test my instructions and verify that it works as intended.

@dh04000 you add code in 2 ways (wirks the same on the forum :

• either as a "span" lile this between back quotes
• either as a block

Like this

Between a pair of triple back quotes. But beware, you must start a new line after each triplet of back quotes. So my block above looks like :
3 back quotes without spaces
Like this
3 back quotes without spaces
Please note that on github you can specify which language is used in a code block. You just need to add the language name right after the opening triplet, say :
3 back quotes python
Like this
3 back quotes

The wiki langiage nme is known as markdown, and github has an advanced markdown for code
