ProffieOS has several spoken error messages. While spoken error messages are meant to be user friendly, it can sometimes be difficult to hear what it's actually saying. Luckily, there is a fairly short list of actual error messages:
This happens when the font specified in your your current preset cannot be found on the SD card. A common reason for this is mispelling the font name in one of the 2 places; the SD card or the preset. They need to be identically spelled with no spaces preferably.
It may also be a path problem. For example "Greyscale/CODA" is not the same as "CODA". The preset's font path must match the folder structure on the SD card.
It could also be if "ProffieOS_SD_Card" sounds were downloaded and put incorrectly on the SD card. What you're supposed to do is to just copy the contents of that directory to the root level of the SD.
If your font directory can't be found AND the name is longer than 8 characters, you may get this error message. Check the path and name of the font folder you specified in the preset and make sure it matched exactly on the SD card.
This means that the board cannot detect the SD card. Either the SD card is not present, it's not formatted as FAT32, or something electrical is wrong.
This means that one or more sound effect files are missing or incorrectly numbered. For instance, if you have hum1.wav, hum2.wav and hum4.wav (but no hum3.wav) you will get this error message.
This happens if the blade array is not configured correctly. The reasons may be complicated, so ask for help if you can't figure it out.
Charge it!
