help setting gpio with rotary encoders

[pisuke74]

hi to everyone

i am from Volumio and in previous system I ve setted

GPIO 27 - 22 function  prev /next title
GPIO 4 - 17   function decrease / increase volume
GPIO 9 - 10  function seek in title

i am using 3 rotary encoder on my dac

i ve read about gpio control in system menu but I don't know what insert in CMD space...

thanks for any help

If I am on correct path.. is there a list of CMD that I can insert?

thanks

Try the mpc commands. Separate the command arguments with a comma when entered into the CMD field of GPIO Config.

Examples:

Code:

# Playback control
mpc,next
mpc,prev
mpc,seek,+10%
mpc,seek,-10%

# Volume
/var/www/vol.sh,up,5
/var/www/vol.sh,dn,5
/var/www/vol.sh,mute

ok thanks. not clear how to use it. how to integrate with the web interface.. is there a walkthrough ? thanks

so if I understand for seek and next I have to set like screenshot and tested works...

also volume works.. but how to set the degrees of knob .. tried to set debounce to 1 (like Volumio) seems great

is there a limit of 8 buttons in moode?

[Tim Curtis]

What do you mean by "how to integrate with the web interface"?
What is your usage scenario that requires more than 8 GPIO?

vol + vol - seek + seek - track + track - . with the 3 knob I have 3 press ... 6+3 = 9... I can use for mute, pause and if possible reboot.. (how can I set pause mute and reboot if possible?

[Tim Curtis]

The GPIO Config screen is limited to 8 pins.

You might want to use a rotary encoder for volume instead of two dedicated push buttons.

ok thanks. I have 3 rotary encoder but they have the push function . 

I use all encoder for volume seek and ff function. ok if limit Is 8

It sounds like you are using up and down on the rotary encoders as discreet buttons? If you look in the Audio Config section of the moOde UI, under the "Volume options" section, you will see a built in rotary encoder volume section which you may find works more like a traditional volume knob (the further you turn the knob, the bigger the effect).

Hey all, not wanting to high-jack the thread so let me know if I should start a new one.

I'm wanting to actually retro-fit an motor encoder into my analogue amp.  I don't want to use the software volume as it effects the quality but I would love to use the mood interface to control the volume of my amp pot.

Is this possible using the setup you describe here or is it only for reading from a rotary encoder?

[Tim Curtis]

You should start a new thread in Support.

Describe the "motor encoder".
