b68d100ae0 o Next step in avoiding the need to re-compile: make hardware GPIO 
mapping choosable at run-time (and hence: via command line flag).
  Now, Adafruit HAT users don't have to recompile.

8462ca7cd6 o Catch a common misconfiguration: Setting ADAFRUIT_RGBMATRIX_HAT_PWM 
but forgetting to set HARDWARE_DESC=adafruit-hat

816b30d67e o Introduce the concept of a StaticTransformer: this is a transformer 
that is applied at the beginning and permanently modifies the internal
  pixel mapping without the need for function calls at runtime.
o This fixes the confusing case that a FrameCanvas does not by default
  get the features of a CanvasTransformer.
o The old transformer interface is kept for backwards compatibility.
  (we might think of having that simplified with a callback function
   or something).
o The new function call is ApplyStaticTransformer(); the old methods
  SetTransformer() and transformer() are still supported but clearly
  marked deprecated.
o This is in preparation to provide different multiplexing (for outdoor
  panels) and have an easier way to provide a transformer in Python.

4db2faf420 o Prepare PixelMapper to be shared between frame buffers, 
owned by RGBMatrix
 2016-09-04 09:14:01 -07:00

6ac91ddfb6 o Remove a couple of branches to speed up things even though 
we now control a lot of stuff with runtime flags instead of
  compile-time #ifdef's

b4b511a459 o Make brightness-lookup less expensive. 2016-09-03 17:52:54 -07:00

f083838032 o Prepare framebuffer for easier central pixel mapping. 
o Preprocessing color bits resulted in pixel-setting 12% faster.

b664571c3d o Allow to set a default options for the CreateMatrixFromFlags(). 
o Allow to set show-refresh-rate, inverse-colors and green-blue
  swap programmatically. That way, nobody has to re-compile just for
  these options, which makes things more easy to distribute as library.
  also: Make these flags.

6c67391c19 o Add support for 'E' line (addresses #120) 
o (does not yet address adapter PCBs. Awaiting feedback where the
  outputs usually are).

a9345e1861 o Make it configurable to only have one sub-panel per panel, as some 
older panels provide that. Fixes #96
 2015-12-05 13:01:23 -08:00
Henner Zeller
e655b7355a o Provide a way to swap green and blue. Some panels out there are 
broken that way.

Henner Zeller
b59f83828d o Choose a base PWM value that is good enough in 'classic' wiring as well 
(Maybe this should be configurable).
 2015-07-19 18:03:51 -07:00

5253075725 o Make multi-parallel the default. 2015-07-19 13:39:09 -07:00

old pinout accessible with RGB_CLASSIC_PINOUT

d6afe7926a o work in progress: proposed new pinout, making sure pin18 is PWM pin 
and while at it, shuffling other bits around.

273b294d5f o Move the concept of a pin-pulser to a class, so that we can create 
different implementations.

b57459be93 o Generally break out row-bits to make it easier to shuffle around 
(also, simplifies as some #ifdefs can go.)

948094211c o Simplify the MULTI_PARALLEL setup. Previously it was a bit confusing 
that it worked with 2 parallel, but not 3. Now, default is 1 (as
  it used to be) and with MULTI_PARALLEL switched on, 2 and 3 is allowed
  as well.
