[How to do instruction] 128x64 OLED with Song Status and Spectrum Display on Raspberry Pi

Hi drei

The order of options doesn't matter. You could add it at the end

Code:

sudo mpd_oled_service_edit -o 3 -b 21 -g 1 -f 20 -c alsa,plughw:Loopback,1 -R

Good day adrian! mind me to ask what command should i use to operate this single button for many function such as eg: i am using rotary encoder ky-040 the middle/switch button that i want to use for
single short press  = play/pause
double press = next
long press like (3sec) = safeshutdown/sudo,poweroff


regards,

Hi drei

Sorry, I don't know.

Hello adrian! It's okay I'm manage to work it now. Long press shutdown and shortpress for next. 
I made a small circuits that avoid interference on each pin. Anyways,thank you for helping me.

Best regards,

Hi everyone! Mind me to know if there's anyone here have tried to use pcm5122 Dacpix920 from https://wiki.geekworm.com/X920
Running with raspberry pi 3b+ and oled display 0.96inch.
I'm a bit frustrated with to work with this. Every time i reboot the system. The i2s driver like st400 or iQaudio dac driver are losing after a reboot/restart.

It seems that dacpi has also controlled by i2c and there's having interference with i2c signal, as you can see here on i2cdetect.
$ sudo i2cdetect -y 1

And after i took i2c wire of oled display and do execute again.

Also, here are the output device after restart the system. 
The output is supposed to be suptronics x400 then it will doing fine. 
Unfortunately , only oled is showing good sign after the restart not the dac hat. But, if i remove the oled from pi the output device is showing again.
It seems the result in alsa also changed.

[fdealexa]

Please try to lower the dtparam=i2c_arm_baudrate=800000 at 400000 and let us know.

It is working fine now so far. after i comment out the all hdmi related so it won't bother to show up in the output device.
