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

[Lucius]

Hi adrii,

Sorry for the late reply, but I've been away.
I don't know how to program on the Raspberry Pi with C++ and yes, the display is part of a kit.

When I tried a fresh copy of Moode 7.3, installed mpd_oled, the display works properly:

Code:

● mpd_oled.service - MPD OLED Display
   Loaded: loaded (/etc/systemd/system/mpd_oled.service; enabled; vendor preset:  enabled)
   Active: active (running) since Sun 2021-07-11 15:00:26 CEST; 9s ago
  Process: 2286 ExecStartPre=/usr/bin/mpd_oled_launch_test (code=exited, status=0/SUCCESS)
 Main PID: 2296 (mpd_oled)
    Tasks: 2 (limit: 2063)
   CGroup: /system.slice/mpd_oled.service
           └─2296 /usr/bin/mpd_oled -o1 -r24 -D27 -b 21 -g 1 -f 15 -R -c alsa,plughw:Loopback,1

Jul 11 15:00:25 moode systemd[1]: Starting MPD OLED Display...
Jul 11 15:00:26 moode systemd[1]: Started MPD OLED Display.

But after the Moode reboot, not anymore. I get the same error:

Code:

● mpd_oled.service - MPD OLED Display
   Loaded: loaded (/etc/systemd/system/mpd_oled.service; enabled; vendor preset: enabled)
   Active: failed (Result: signal) since Sun 2021-07-11 15:03:23 CEST; 23s ago
  Process: 413 ExecStartPre=/usr/bin/mpd_oled_launch_test (code=exited, status=0/SUCCESS)
  Process: 1042 ExecStart=/usr/bin/mpd_oled -o1 -r24 -D27 -b 21 -g 1 -f 15 -R -c alsa,plughw:Loopback,1 (code=killed, signal=ILL)
 Main PID: 1042 (code=killed, signal=ILL)

Jul 11 15:02:33 moode systemd[1]: Starting MPD OLED Display...
Jul 11 15:03:23 moode systemd[1]: Started MPD OLED Display.
Jul 11 15:03:23 moode systemd[1]: mpd_oled.service: Main process exited, code=killed, status=4/ILL
Jul 11 15:03:23 moode systemd[1]: mpd_oled.service: Failed with result 'signal'.

I tried Moode 7.2.1 again and it doesn't work there either and it behaves the same as on Moode 7.3.0.

Sorry for my english

Edit: After removing 'dtparam=spi=on' from '/boot/config.txt' I get now this:

Code:

pi@moode:~ $ sudo /usr/bin/mpd_oled -o 1 -r 24 -D 27 -b 21 -g 1 -f 15 -c alsa,plughw:Loopback,1
Illegal instruction
