Henner Zeller
b102ca6b57 o Make compiler flags as well part of the dependencies which 
allows easier playing around with flags.

b0e4d071c2 o Better define dependencies that library is re-built on changing 
the framebuffer-internal.h header file. Addresses compile issue
  found in #61

71d787e6ab o Reduce image size to improve download experience. 2015-07-27 21:12:24 -07:00
Henner Zeller
ffd853e5f4 o Add a pullup for OE to overcome the (weak) pull-down that comes 
up by default on boot. That way, we are not exposing the matrix
  to a low OE with static pixels.
 2015-07-27 21:02:52 -07:00

1627ee7a14 o Make generated sources a separate dependency that someone can 
explicitly invoke.

f293053346 o Improved directory structure of Python code. 
o Use some new features in python examples.
 2015-07-23 23:44:27 -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.

the side of original connection at the RPi.
