Updfating Library

[hokuto123456789]

hello. Please let me know because I can't get it right while I'm creating it.

1. Put MP3 files in Music folder
2. Menu Settings Select Update Library

I get an error like the one below and can't return to the menu.
Is there a solution?

pi@raspberrypi:~/PiPod_ePaper/Software $ python3 main.py
Traceback (most recent call last):
File "/home/pi/PiPod_ePaper/Software/main.py", line 142, in
music.updateLibrary() # Re-create the info.csv file
^^^^^^^^^^^^^^^^^^^^^
File "/home/pi/PiPod_ePaper/Software/playback.py", line 283, in updateLibrary
stringTitle = newtitle[0].lstrip()

I can think of a few things to do:

• look at the info.csv file. It should contain a CSV list of titles, artists, etc...
• look at the playback.py code near the end (lines 330-334). There are some debug print lines you can un-comment to see what the code sees as it parses the files in the Music directory.
• Make sure either your music files have filenames like "James Taylor - Steamroller.mp3" AND that the UseMeta is set to False (line 15), OR
• Set UseMeta to True. Once set to True, info.csv will be built/made/created using the metadata contained in the music file itself, ignoring the file names.

My guess is that the lines 330-334 will print out which music file(s) are causing a problem during the creation of info.csv.

If all else fails, you can modify the parser to extract the music file metadata from whatever system/method your filenames use.

Thank you. If you set the file name of the music file to something like "James Taylor - Steamroller.mp3", it will be recognized. I couldn't find this rule.
・ I was able to play music, but it is full of noise, so I will try to find the cause.
When D2 is removed, there is noise, but D2parts are arranged and reattached.

I'm talking about D2, not D1, but it always makes noise whether it's USB powered or battery powered. Is there a solution?
Especially when running on battery power, the noise gets louder and you can't hear the music.
Bluetooth and Wi-Fi are also turned off.

I created two boards, and both have the same symptoms.
