it. All of the boards in the system
must
be included in the script. It is
permissible to have a board in a system with no actions assigned to it,
however.
Insufficient power
All Spectacle boards can be powered over the 1/8" (3.5mm) TRRS jack
cable which connects them. However, a couple of boards (currently, the
Motion and Light boards) have a USB micro B connector on board to
provide extra power to the motors or LED strips attached to the board.
How do you know if you need to attach another power supply? Well, the
easiest way is to try and see. If your system behaves oddly, or doesn’t work
at all, you probably need more power than can be provided by the Director
Board and should attach a supply at the output board.
If you are attaching more than 20 LEDs or more than one of the smallest
size servos (or any of the larger servo motors), you should power the output
board locally.
Configuration failed to install properly
Sometimes, the upload just doesn’t take properly. Usually this is due to the
volume on the programming device having been set too low, or to another
sound (a notification tone, for instance) playing on the programming device
during the configuration installation process.
The solution here is simple: try installing again. If your volume
is
all the way
up, it’s possible that your device can’t make a strong enough signal to work
with Spectacle. This may be especially true of cellular phones in the EU,
where maximum volume output is limited by statute.
Single LED blink on Director Board at power up
This means the system failed to initialize properly. This can be because the
board order is wrong, there’s an extra board in the system, one of the
cables isn’t connected firmly, one of the cables has been damaged, or
because the installation of the program went badly.
Typically, the best way to fix this is by checking connections and board
order, reinstalling the code, and (if possible) swapping out the interboard
connection cables with other, known good cables.
