# 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.

# 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.
