# Configure the rpi-rgb-led-matrix library here:
# The -DADAFRUIT_RGBMATRIX_HAT value configures the library to use the Adafruit
# LED matrix HAT wiring, and the -DRGB_SLOWDOWN_GPIO=1 value configures the
# library to work with a Raspberry Pi 2.  For a Pi 1 (or perhaps even on a Pi 2,
# but I found it necessary in my testing) you can remove the -DRGB_SLOWDOWN_GPIO=1
# option.  You can also add any other rpi-rgb-led-matrix library defines here
# to configure the library for more special needs.  See the library's docs for
# details on options:
#   https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/lib/Makefile
