97247b7698 o Update documentation. 2016-08-25 09:46:18 -07:00
Henner Zeller
4ade855471 o for parsing flags and creating matrix from options, don't make 
parameters optional.
 2016-08-23 20:20:59 -07:00
Henner Zeller
ddf446d952 o Separate out flag parsing and creation of matrix into separate 
functions to call.
 2016-08-23 19:41:00 -07:00
Henner Zeller
810c54f849 o Allow hardware pin pulsing select also to be set programmatically 
and via flag.
 2016-08-21 20:01:51 -07:00
Henner Zeller
85e707116f o Allow to choose the lsb pwm nanoseconds on the command line. 2016-08-21 17:02:54 -07:00
Henner Zeller
6d26807d88 o Making dropping privileges the default. 
o Make it possible to select scan mode programmatically.
 2016-08-21 16:24:29 -07:00
Henner Zeller
d5286000ce o add the concept of RuntimeOptions. This contins the daemon, drop-privs 
and gpio slowdown values.
o Add gpio slowdown to the values that can be modified programmatically
  and with flags.
o Have the default flags passed into CreateMatrixFromFlags() also be
  an output value, so that the settings read from the flags can be
  used back in the user program.
 2016-08-21 15:58:23 -07:00
Henner Zeller
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.
 2016-08-21 12:54:45 -07:00
Henner Zeller
51db6ce6d0 o Better documentation and more flexibility with daemon option. 2016-08-21 10:57:48 -07:00
Henner Zeller
7557c40e17 o Add some common runtim options (--led-daemon, --led-drop-privs) 
o Add more options for matrix parameters (--led-brightness, --led-pwm-bits)
 2016-08-20 19:26:20 -07:00
Henner Zeller
edce0acadb o Initial parsing of matrix command line options. 2016-08-20 17:25:06 -07:00
Henner Zeller
eb0a10b0f0 o Provide an RGBMatrix::Options struct as input for all parameters. 
Preparation to have other parameter tweaks move from #defines to
  runtime options.

5543956e8a o SwapOnVSync(): make it possible to choose a fraction of the refresh-rate 
as animation timing for applications that want to lock the update
  to the refresh rate.
  Usually, the refresh rate in the several hundred Hz range is not
  as useful for that.

  Adds a feature that emerged in a discussion in issue #184.
 2016-07-26 20:55:40 -07:00
Henner Zeller
dc67b42aa4 o Minimize dark-time for longer display chains (addresses 
issue #180).
o Expose the LSB pwm time as a settable #define
o Update documentation for various #defines in lib/Makefile
 2016-07-23 16:37:04 -07:00
Henner Zeller
409d7bd3ce o Add a C-API (experimental right now, don't use yet) 
o Provide a shared library
 2016-05-05 08:29:51 -07:00
Henner Zeller
a559db250b o Allow to separate setting GPIO initialization from thread starting 
(but keep same defaults).
 2016-02-14 11:12:55 +00:00
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.

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.

cde792d762 o Make slowdown of GPIO switchable. Make it default off, because the 
old Raspberry Pis should typically do fine (but their performance hurts
  a lot if this is switched on).
o Exposes the setting experimentally added in issue #16 in the Makefile.
o Update README describing what to do in these cases and how to switch
  it on.
