[HELP] AUDIOPHONICS I-Sabre V3 DAC ES9023 TCXO

guillaumesej

Hi,

I didn't modify the 16x2_oled_runeaudio.py script: this is the one I downloaded from this forum thread.
I already contained the

LCD_D7 = 27

line.

Also, running the script manually, and adding some debug print () in some places does print LCD_WIDTH = 16, so I guess the value is passed properly.

rikardo1979 wroteI would like to change the switching time between artist-title and also I would like to see IP address on display instead of runeaudio.local
search for "hostname --fqdn" and replace it with "ip route get 1 | awk '{print $NF;exit}'". This should display the IP instead of the hostname. The script is written a little strange. Wonder that the RasPi still has the time to play music.
thanks, working fine
Feel free to write a better one
Me and many more, we would be more than happy to use it

edit: any idea how to extend time delay between displaying artist-track info?
That is one of the last thing I miss

any help on this anyone please?

rikardo1979

It is very strange how is all the information on OLED updated?!?

Any idea how to fix this? To do normal 1s update of the playback time and 5s delay between artist/track information?

Give this a try...

thx, but OLED wont even come ON with this script. Not a single dot.
Maybe you can write down what your changes are?

edit: I can see at least one mistake

# Define GPIO to LCD mapping
LCD_RS = 7
LCD_E  = 8
LCD_D4 = 25
LCD_D5 = 24
LCD_D6 = 23
LCD_D7 = 15

should be

# Define GPIO to LCD mapping
LCD_RS = 7
LCD_E  = 8
LCD_D4 = 25
LCD_D5 = 24
LCD_D6 = 23
LCD_D7 = 27

So I have tried to change and reboot but still no good

Hi Rikardo,

this script (oled.py) is for version2.

You have to change the line

LCD_D7 = 15

LCD_D7 = 27

You should stop the "old" script and try the new one from commandline first. Maybe you have to change "...python" to "...python2" in the first line.

I did as I remember you mentioned this to me in past. but still no go

Hi Rikardo,

- where did you save the script?
- did you rename it?
- did you change the service file?
- what is the output from:

python /path-to-script/oled.py

?

Frank

- /usr/local/bin
- yes
- not sure what you mean by this

Rikardo,
I don't have an LCD/OLED attached to my Raspi, but the modified script should work. You may try the following and post back the output of the last commands. If the last command doesn't put any output you may remove the "#" in line 221 in front of the print command. Then everything put to the oled is also printed on the screen.

systemctl stop oled.service

Backup your old /usr/local/bin/16x2_oled_runeaudio.py and copy the attached oled.py to /usr/local/bin/16x2_oled_runeaudio.py

Now post the output of the follwing commands:

ls -l /usr/local/bin/16x2_oled_runeaudio.py
/usr/bin/python /usr/local/bin/16x2_oled_runeaudio.py

Rikardo,

there must be another OLED-Script running on your Raspi. So the ports are already in use as the output says. You could disable the oled service for the moment with

systemctl disable oled.service

then reboot and try again

/usr/bin/python /usr/local/bin/16x2_oled_runeaudio.py

Later you can enable the service again for autostart with

systemctl enable oled.service

rikardo1979

tried again

I had to uncoment that print line otherwise I had hang terminal. But than

[root@runeaudio ~]# /usr/bin/python /usr/local/bin/16x2_oled_runeaudio.py
^C[root@runeaudio ~]# /usr/bin/python /usr/local/bin/16x2_oled_runeaudio.py
  File "/usr/local/bin/16x2_oled_runeaudio.py", line 223
    message = message.center(LCD_WIDTH," ")
                                          ^
IndentationError: unindent does not match any outer indentation level

ingohz

the print line has to begin in column 3. Otherwise you have a wrong indentation level. At your first try there was no output on the oled?

rikardo1979

There is one thing I really hate, and that is digging into code

So I think I just keep what Frank made

But thanks for your effort

Here is a great how to guide from @dhrone on github

Works like a charm

Hi Rikardo,

happy to here that it works now.

A bit disappointed that users have to fix the stuff

I confirm it works for me as well, this is a great job !
