This will only work on rooted goggles
An ipk
package is available in the releases section and can be installed via opkg
.
Use adb
to copy everything in place and make it executable on the goggles:
adb push scripts /blackbox
Make sure that the /blackbox/scripts
is part of your PATH.
To draw a symbol to the LED Matrix invoke from the blackbox
directory like so:
led-draw-char A
Have a look at the example script to see how to chain multiple draw operations.
To see all possible options run:
led-draw-char -h
To draw a string to the LED Matrix invoke run:
led-draw-string "BOOBS" 0.75
The second parameter is how long each character should be shown in seconds.
