//
// The data stream seen by the last LED in the chain will be delayed by
// (count - 1) clock edges, because each LED before it inverts the clock
// line and delays the data by one clock edge. Therefore, to make sure
// the last LED actually receives the data we wrote, the number of extra
// edges we send at the end of the frame must be at least (count - 1).
// For the APA102C, that is sufficient.
//
// The SK9822 only updates after it sees 32 zero bits followed by one more
// rising edge. To avoid having the update time depend on the color of
// the last LED, we send a dummy 0xFF byte. (Unfortunately, this means
// that partial updates of the beginning of an LED strip are not possible;
// the LED after the last one you are trying to update will be black.)
// After that, to ensure that the last LED in the chain sees 32 zero bits
// and a rising edge, we need to send at least 65 + (count - 1) edges. It
// is sufficent and simpler to just send (5 + count/16) bytes of zeros.
//
// We are ignoring the specification for the end frame in the APA102/SK9822
// datasheets because it does not actually ensure that all the LEDs will
// start displaying their new colors right away.

This is the Linux-penguin again...
Originally drewn by Larry Ewing (http://www.isc.tamu.edu/~lewing/)
(with the GIMP) the Linux Logo has been vectorized by me (Simon Budig,
http://www.home.unix-ag.org/simon/).
This happened quite some time ago with Corel Draw 4. But luckily
meanwhile there are tools available to handle vector graphics with
Linux. Bernhard Herzog (bernhard@users.sourceforge.net) deserves kudos
for creating Sketch (http://sketch.sourceforge.net), a powerful free
tool for creating vector graphics. He converted the Corel Draw file to
the Sketch native format. Since I am unable to maintain the Corel Draw
file any longer, the Sketch version now is the "official" one.
Anja Gerwinski (anja@gerwinski.de) has created an alternate version of
the penguin (penguin-variant.sk) with a thinner mouth line and slightly
altered gradients. It also features a nifty drop shadow.
The third bird (penguin-flat.sk) is a version reduced to three colors
(black/white/yellow) for e.g. silk screen printing. I made this version
for a mug, available at the friendly folks at
http://www.kernelconcepts.de/ - they do good stuff, mail Petra
(pinguin@kernelconcepts.de) if you need something special or don't
understand the german :-)
These drawings are copyrighted by Larry Ewing and Simon Budig
(penguin-variant.sk also by Anja Gerwinski), redistribution is free but
has to include this README/Copyright notice.
The use of these drawings is free. However I am happy about a sample of
your mug/t-shirt/whatever with this penguin on it...
Have fun
