[HELP] AUDIOPHONICS I-Sabre V3 DAC ES9023 TCXO

[rikardo1979]

Hi Rikardo,

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

Code: Select all

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.

Code: Select all

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:

Code: Select all

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

Code: Select all

systemctl disable oled.service

then reboot and try again

Code: Select all

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

Later you can enable the service again for autostart with

Code: Select all

systemctl enable oled.service

[rikardo1979]

tried again

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

Code: Select all

[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

Hi Rikardo,

happy to here that it works now.

A bit disappointed that users have to fix the stuff
