6c67391c19 o Add support for 'E' line (addresses #120) 
o (does not yet address adapter PCBs. Awaiting feedback where the
  outputs usually are).
 2016-05-05 10:31:14 -07:00
Henner Zeller

o Provide a shared library
 2016-05-05 08:29:51 -07:00

 2016-02-14 11:12:55 +00:00
Henner Zeller
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
79c4cff787 o Make 64-bit value from hex parsing independent of platform 
specific interpretations of 'long long'.
 2015-12-03 04:22:14 +00:00
Henner Zeller
e655b7355a o Provide a way to swap green and blue. Some panels out there are

  Fixes #58

Henner Zeller
90283819e5 o minor style issues. 2015-12-01 22:33:15 -08:00
Ian Foster
d7fd1fb561 o Added support for background colors on DrawText and DrawGlyph 
o Make the versions with the background the default functions, keep
  the old versions merely for compatibility.
 2015-12-01 22:30:55 -08:00
Henner Zeller
63a5da1bad o Update and clarify documentation for the ADAFRUIT_RGBMATRIX_HAT_PWM 
o Take extra precaution that the hardware hack needed for the HAT-PWM
  does not clash with GPIO 4 being set as output on the system for
  some reason.
 2015-11-25 23:38:50 +01:00

3e41f8d2e0 o Switch on GPIO slow-down by default. Limits support requests. 2015-11-19 23:02:24 -08:00
Henner Zeller
333397e815 o Fix platform-dependent assumption of lenght of off_t. Apparently 
in some contexts it is considered 64 bits on the Pi, which doesn't go
  well with a fixed sscanf() integer-width pattern. Tie it to a fixed
  type. Found by Maxime Journaux working on a nodejs binding.

Henner Zeller
08023d418a o Bind display refresh to one CPU core to avoid flicker-inducing kernel 
jumpiness.
 2015-10-12 00:33:36 +00:00

6890187140 o Make sure that no copy-constructor is used for Font. 2015-09-29 23:59:25 -07:00
Henner Zeller
6de71219ff o Some documentation clarifications. 2015-09-29 08:41:06 -07:00

6d2383c6b6 o Make ThreadedCanvasManipulator restartable (fixes #60) 2015-09-13 16:26:31 -07:00
Henner Zeller
246becad2e o Add a way to slow down even more. 2015-09-13 14:08:22 -07:00
Henner Zeller
476700843e o Ignore compiler-flags file in git. 2015-08-27 10:42:30 +02:00
Henner Zeller
b102ca6b57 o Make compiler flags as well part of the dependencies which 
allows easier playing around with flags.
 2015-08-27 10:39:00 +02:00
Henner Zeller
b0e4d071c2 o Better define dependencies that library is re-built on changing 
the framebuffer-internal.h header file. Addresses compile issue
  found in #61
 2015-08-27 10:15:48 +02:00
Henner Zeller
cf252fbf4a o Proper brightness clipping and documentation added. 2015-08-15 11:55:07 +02:00
Henner Zeller
55ff2662ba o Make sure the actual active frame is set after SwapOnVSync(). 2015-08-04 11:43:55 -07:00

7a0da0e136 o Add new transformers to provide logical Canvases that are transformed 
before writing to another physical Canvas.
   - RotateTransformer: rotates by multiple of 90 degrees
   - LargeSquare64x64Transformer: does the 64x64 conversion from
     earlier examples
   - LinkedTransformer allows to have a sequence of transformers
     applied.
o Provide a flag in demo-main to influence rotation.

71e74ce597 o Some README tweaks. 2015-07-23 17:29:37 -07:00
Henner Zeller
a662b54a19 o More datasheet reading helps 
- simplified way to generate pulse timing; not using serializer just
    simple base PWM, but using value == range. That way, we don't have
    to switch timing in-between.
  - measurements with oscilloscope for things that are omitted from
    the datasheet.
o Measure time elapsed between SendPulse()/WaitPulseFinished(), then
  sleep for amount needed before busy-waiting on for the pulse to finish.
o Results: brigther (less 'dead time'). Better refresh rate (dito).
  Less CPU use.
 2015-07-23 00:17:59 -07:00
Henner Zeller
493ccc0ce6 o Make sure PWM registers are properly set to default values. 
o remove some old debugging code.

349fd3ab02 o Make use of PWM timer switchable. 2015-07-19 18:39:21 -07:00
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
Henner Zeller
941f71e350 o Less chatty about pulser used. 2015-07-19 13:40:49 -07:00

old pinout accessible with RGB_CLASSIC_PINOUT
