When the board is powered on, the card detect LED will blink until a SD card is inserted.
NOTE: Insert the microSD card with the gold fingers facing upwards! It can only go in
one way.
When the card is detected, the CD LED will stop flashing and illuminate. This means the
board is initialized and ready. If a boot sound is configured to play out, it will playback
at this point.
The sound active LED illuminates once the sound module input is triggered. This means
the board is actively playing out sounds and monitoring the accelerometer.
The force feedback pads are used to attach a vibration motor. The board will control the
motor and synchronize it will clash and swing sound playback. You can use any type
pager/vibration motor with your sound board (motor operating voltages: 1.5-12V)*.
FILE SYSTEM FOR SD CARD
The SD card used is a standard microSD card. Any size card can be used, and the smaller
1-2Gb cards are less expensive to find.
When you get your card, it should be formatted already. If not it can be formatted under
Windows File manager. A normal FAT type file system can be used.
The sound files stored on the card are standard WAV formatted mono sound files. The
sample rate, channel size, and bit length are auto detected for you, so you do not need to
edit your sound files into any kind of proprietary format. For simplicity the audio format
should follow the hum sound file format. We will be using a sample rate = 22050 Hz and
bit length = 8. You can use any standard sample rate for your files (8kHz, 11.025kHz,
22.050kHz, 44kHz). We have found that for saber type sounds a sample rate of 22kHz is
more than sufficient.
The SD card will be a normal removable drive under Windows. With the card in a card
reader, you can copy your sound files into the root directory of the SD card.
NOTE: The files must adhere to our naming convention in order to operate properly.
Here is a list of files that the sound board will auto detect:
on<xx>.wav
– Ignition sounds, you can store up to 10 sounds. <xx> are numbers 1-10
off<xx>.wav
– Retraction sounds, you can store up to 10 sounds. <xx> are numbers 1-10
swing<xx>.wav
– Swing sounds, you can store up to 20 sounds. <xx> are numbers 1-20
clash<xx>.wav
– Clash sounds, you can store up to 20 sounds. <xx> are numbers 1-20
