5c168a2170 o Use additional GPIO pins on Plus models and Raspberry Pi 2 to 
drive a second parallel chain. 100% more panels for 0% more CPU :)

7fcb7ff79a o Pull out sleep_nanos() and move implementation 
separately, as it is hardware dependent.

1c1b0108c5 o Make luminance function a lookup table. 2014-09-10 07:30:33 +00:00
Henner Zeller
9c22cf8d2d o Ignore the black time for clocking and use the freedom to use 
shorter PWM base-time. Which then is used for 11 Bit PWM.
o implement CIE1931 luminance correction. Switch on by default.

b1f646057f o Move Canvas into separate file as preparation to be referenced 
in a little graphic primitives library later.
o Rename some methods while they are hopefully still not being used
  to much elsewhere: FillScreen() and ClearScreen() just becomes
  Fill() and Clear(). The affect a Canvas, not necessarily a Screen.
