PiGlow is a GObject for manipulating the
PiGlow add-on board for
the The Raspberry Pi. It wraps the low-level communication in a
high-level API. This makes it very convenient to program the PiGlow
from C and C++.
Apart from the functions to get/set the LEDs, there is a function
pi_glow_animate, which allows you to define animations, frame by
frame, using a callback-function.
Usage is straightforward; see piglow-main.c for an example.
