Example:
The LEDs display the following code:
The LEDs display the following code:
All off, [(1 dim, 1 dim, 1 dim) (1 bright, 1 bright, 1 dim) (1 dim, 1 dim, 1 dim)], all
off, [repeats up to 10 times].
This LED pattern (between the brackets [ ] in the example above) represents a code
of 000 110 000. Removing the leading 0 results in a binary code of 0011 0000, a
hexadecimal value of 0x30). You refer to the error codes in this document and see
that this error indicates that the image length is incorrect.
