Troubleshooting & FAQ
Q
: I’ve updated the sounds on the SD card and now the module does not work
anymore. It generates some beeps when it starts.
A
: you must format the SD card (in FAT16 / FAT32) before updating the sounds,
while it’s not necessary to do so for the configuration files that can be edited in place
on the SD card. To simplify the update process, put the new sounds on the SD,
overwrite the old ones. Then select the whole contents of the SD card, and copy it in
a temporary directory/folder on the hard disk. Format then the card, and next copy
the files back to the SD card in one run.
Q
: what’s the meaning of the beeps when the module starts.
A
: it means that a file is missing or hasn’t been found. It can be the boot sound, or
the configuration files. Three beeps generally mean that many important files haven’t
been found. You can get more details about what’s happening by hooking up your
RICE cable, connect, and press ctrl+M (apple key + M on mac) to display the debug
window and see the boot log of your board. Add debug=1 at the beginning of your
configuration file for additional information.
Q
: when I power up the saber, I get 3 beeps. I haven’t updated the card.
A
: You might have a corrupted preference file (
prefs.txt
). Get the default one
from the default package.
Q
: can I rename the sub-folders on the SD card ?
A
: no, the module expects a certain organization of the file system on the card so
that it can find the sounds.
Q
: I don’t have the aux. Button wired, can I rename the sub-folders to « swap »
them ?
A
: no, because it will modify the SD card file structure. Wire an auxiliary button to
access the different sound banks.
Q
: I wired a rumbling motor in my hilt and now I have swings triggered while the hilt
rests on a flat surface.
A
: The motor makes the board vibrating enough so that it’s interpreted as a swing.
Reduce the speed of the motor and/or mechanically isolate the board from the motor.
Increasing
ls
can also help, but it will make swings more difficult to execute.
