You have modified the script (LCD_D7 = 15 to LCD_D7 = 27) right?
As LCD_WIDTH is the next variable in the source, i think something went wrong doing this.
Please download the script an other time and try it again.
Do not use the standard windows editor to modify the file.
Use nano on your Pi or Notepad+ on your windows pc.

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
Code: Select all
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.

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?

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?

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


Code: Select all
# 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


Code: Select all
# 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
Code: Select all
LCD_D7 = 15

to
Code: Select all
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.

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
?
