# The signal can be too fast for some LED panels, in particular with newer
# (faster) Raspberry Pi 2s.
# In these cases, you want to make sure that
#   - The cables are short enough from the GPIO header to the panel.
#   - Maybe use an active level shifter and bus driver, for instance by building
#     up one of the adapter-PCBs in the ../adapter/ directory or use
#     the Adafruit HAT. The output drivers of the GPIO are not really good
#     in driving long cables - this will improve the situation.
#
# If the above fails or you can't implement them, try uncommenting the
# following line and recompile; it will slow down GPIO, but will as well reduce
# the frame-rate.
#DEFINES+=-DRGB_SLOWDOWN_GPIO

# Uncomment to allow to use up to three parallel boards.
# This will only work on the plus models or RPi2 with 40 GPIO pins.
#
# This is useful in any case, _unless_ you have an older installation with
# classic cabeling of previous versions of this library or a
# Raspberry Pi 1, Revision 1 (very old).
#
# The reason why this is disabled by default is that it is not compatible with
# GPIO cabelings of previous versions of this software and thus is already
# wired up 'in the field'. Also it will drop support for the very first
# Raspberry Pi, Revision 1.
# Hence we leave this off for now for the least amount of surprise.
#DEFINES+=-DSUPPORT_MULTI_PARALLEL

# If you see that your display is inverse, you might have a matrix variant
# has uses inverse logic for the RGB bits. In that case: uncomment this.
#DEFINES+=-DINVERSE_RGB_DISPLAY_COLORS

# Uncomment the following line for Adafruit Matrix HAT gpio mappings
#DEFINES+=-DADAFRUIT_RGBMATRIX_HAT
