Hi,
I’m using the rotary encoder plugin, installed through the plugins menu. When I set everything up, the encoder works perfectly, but after I restart volumio, it stops working. If I open the rotary encoder plugin menu and just hit the save button it will start working again.
I’m using Volumio version 2.834 and Rotary Plugin version 1.2.2, on a Raspberry Pi 3 Model B.
I’m using GPIO 27 for CLK and GPIO 22 for DT on the rotary encoder.
I’m also using the Official 7" Raspberry Pi touchscreen display and a pHAT DAC.
The pHAT DAC uses GPIO 18,19 and 21, so I don’t think it’s an I/O conflict.
The encoder is a Spectrol DE2-0-1-32 ( http://www.farnell.com/datasheets/319882.pdf )
I have the input (Vs) pin connected to 3V3 (pin 1) and the common pin connected to GND (pin 9). The output signals are clean and the encoder has built-in CMOS debouncing.
Any suggestions as to why the encoder stops working after a restart?
I’ve somehow got this working, but I don’t actually know how.
Here’s basically what I can remember doing…
I took a copy of the rotaryencoder plugin from /data/plugins/user_interface/rotaryencoder
and placed that in ~/ so I have ~/rotaryencoder
I added an extra debug line somewhere in the index.js file of the plugin to check that any changes I made were rippling through
Then I cd into the plugin folder and did: volumio plugin refresh volumio vrestart
After this, the rotary encoder continued to work after a restart, although the changes I made should have made no functional difference.
So then I undid the changes and refreshed and restarted again.
So now I effectively have undone all changes, so the files are back to how they originally were, but now the rotary encoder works after restarting!
I honestly wish I knew why this has “fixed” it, but I’m afraid that’s all I’ve got!
Hi. Do you have any further details on what you did to get this rotary encoder working? I too have the same problem. When I first start Volumio the encoder does not work. If I open the plug-in settings and without changing any settings I hit the ‘save’ then it works fine until next time I shut down and re-start.
I am also using Volumio version 2.834 and plugin version 1.2.2
My rotary encoder is a KY040
As far as I can tell, I literally only did what I outlined above. I’m not particularly savvy with Linux stuff, so I used Filezilla to copy the plugin folder from /data/plugins/user_interface/ to ~/ and then ran those two commands and it seemed to work. I feel like I must have done something else, but I don’t know what, if anything. It’s still working now, weeks later.
Thanks for the help so far. The problem for me is that I have absolutely no experience in using python and don’t know where to start.
Al I have done with my Volumio installation is to add a couple of lines to the config file using notebook. This was to enable me to use a shut down button and indicator lamp. Other than that I have been using Volumio ‘out of the box’ except for installing a couple of plugins.
I don’t know how to sort this. Any ideas?
Further info.
I have now managed to get to my Volumio from my Win10 PC by enabling SSH.
I opened in putty and now am beginning to feel my way around. If you could clarify what you mean by ~/ rotary encoder - the location that you pasted the copied file into, I could give it a try.
I have tried going into Linux files and making changes. I seemed to have only caused more problems so I reinstalled everything.
Is there no other way to get over the problem with the rotary encoder not working after a restart?
Has it never worked with the plugin or is there maybe an earlier version I can use that works? Apart from this problem, my rotary encoder works perfectly as a volume control.
Hi and thanks for your reply. I just had a look at the link you gave but it looks a bit beyond my knowledge and abilities.
Could you possibly explain to me (a complete beginer) how to do what you did - to get it to boot using systemd.
Ok. Many thanks for that. I have had a look through the coding. I will change a couple of things to match my setup. My gpio pins will be different so I’ll change those to suit. Also, I am not using the push button through the plugin at the moment but have set it in another plugin. I am thinking that I can just delete any lines that you have in there for the push-button.
As I am a beginer, it may take me some time to get this working but I will report back when I get there.
