Guten Tag, Manuel, and welcome to the forum.

You'll find a lot of good company here including some other musicians. Sadly, I'm not...but I just attended a great Chris Botti concert last night.

It sounds like you are well on your way with moOde. Vielen Spass!

Hi Kent,

thank you for the warm welcome!
You may be right, at least another bass player has already contacted me ... (Hi Dorffen )

Surely your concert was great ....  my next one will be a gig of "The Hooters" - I'll let myself be surprised.

Concerning MoOde ... Well, I still stumble a lot:

As written in my last post, I replaced my previous Pi 4B board with a Pi 5B. Unfortunately, my connected (SPI) OLED display remains dark, even though I followed Adrian's great instructions meticulously. I repeated the test with a completely new installation of the SW and identical HW wiring: It works with the Pi 4, but not with the Pi 5 - too bad. I hope, I'm not alone with this issue .... so I will write a Post in the Support-section ...

Regards,

Manuel

Hi Manuel,
Welcome on board.
As already reported to Adrian, I had the same issue with moOde 9. A temporary workaround is to install from source instead of binary: please try to follow the Adrian instructions on his github.
Best regards,
Francesco

Hello Francesco,

thank you very much for your help !
I had already read your posts with Andrii and chose the source installation - unfortunately without success: The display remains dark with the Raspberry 5.
One reason will certainly be, that my display is a 2.42 inch OLED with SSD1309 processor... too bad, I'll probably have to stay with the Raspi 4.

Hi Manuel ,
Is your OLED with I2C interface (4 wires)?
Try the command

Code:
i2cdetect -y 1

To see if the device is correctly connected and runnng.
Regards,
Francesco

RE: Hello everybody .... :-) greetings from Germany - lepetitdiable - 06-07-2024

Hello Francesco,

Thank you very much for your help.

My player, which already works with a Pi 4, is connected to the display via SPI.

Rewiring would be difficult here (... but not impossible!)

This is how I wired both Raspberries (Pi 4 and 5) :

So I'll try the I2C variant - at least that would still be an alternative.
I haven't installed my Pi 5 yet and have another display for testing.
I'll get back to you as soon as I have a result - but it may be a while before I'm ready.

Regards,
Manuel

RE: Hello everybody .... :-) greetings from Germany - fdealexa - 06-07-2024

Hi Manuel,

With the OLED configurated as a spi device, could you please try to run

Code:
sudo raspi-config

option 3 (interface), enable spi.
After that please give these commands:

Code:
le -l /dev/spi*

lsmod | grep spi

And let us know the results.
Regards,
Francesco

P. S. The connection you showéd, seems correct.

Hi Francesco,

yes, I had already activated SPI in config.txt (to be on the safe side, I activated it again as desired and rebooted)

Oh dear, now you've caught me out cold: my Linux knowledge is pathetic.
Unfortunately, my system (and I ;-) ) can't do anything with the command ‘le -l’:

Code:
mg@moode:~ $ le -l /dev/spi*                                                                                         

-bash: le: command not found

I was so bold as to assume a spelling mistake and simply entered ‘ls -l’, that's what I got:

Code:
mg@moode:~ $ ls -l /dev/spi*

crw-rw---- 1 root spi 153, 2 Jun  9 14:34 /dev/spidev0.1

- and for the last command I got this answer:

Code:
mg@moode:~ $ lsmod | grep spi

Hope It helps ...

Thank you !

RE: Hello everybody .... :-) greetings from Germany - fdealexa - 06-09-2024

Hi Manuel,
I asked to use the "raspi-config" because the config.txt is now located in the / boot/firmware folder.
Now last question is: how is the mpd-oled invoked, in other words the command line you use to.
Best regards,
Francesco
P.S. sorry for le instead of ls

RE: Hello everybody .... :-) greetings from Germany - lepetitdiable - 06-09-2024

Hi Francesco,

the call is

Code:
sudo mpd_oled_service_edit -o 7 -r 25 -D 24 -b 21 -C 1 -g 1 -f 20 -c alsa,plughw:Loopback,1

(just like I do it with the Raspberry 4).

Haha, I had fun with the ‘le’, I didn't want to look completely stupid ... ... and searched like a big one Smile

G**gle has a new friend now.
No problem, Francesco ...
Thanks again for your help!

Manuel

RE: Hello everybody .... :-) greetings from Germany - fdealexa - 06-09-2024

Manuel,
Have you (obviously yes) enable metadata and loopback?
Would you please try to change the option: Config -> System -> Startup option to Firmware Mode (Legacy)?
Have you already tryed to run mpd-oled on rpi4 and moode 9.0?
Regards
Francesco

RE: Hello everybody .... :-) greetings from Germany - lepetitdiable - 06-10-2024

Hi Francesco,

... what a day:
first I tried a Raspberry 4 with an 8.3.9 version -> the display works fine... ,
then installed a 9.0.1 version + cava + mpd_oled on the Raspberry 4: the display works here too...

Last but not least, I completely reinstalled everything on the Raspberry Pi 5: Version 9.0.1 + cava + mpd_oled ...
The display refuses to work !.

I have switched ON ‘metadata’ and ‘loopback’ on all versions - also on the Raspberry 5.

Under ‘Config -> System -> Startup option’ I have set the following options under Moode 9.0.1 on the Raspberry 5:
‘Worker response’ set to ‘default’,
‘CPU governor’ set to ‘On-Demand’ and
‘PCI express’ set to ‘Off’.

Unfortunately I could not find the option (‘Firmware Mode’) here...

Regards,
Manuel

Hi Francesco,

Hum... surprise, surprise Huh

I'm sorry, I can't set this option:
This are my possibilities ...
