Lib for manipulating cascaded 595 shift registers

Hi!

For debugging purpose, I needed manipulating LEDS so I can easily set LEDs on/off according to events in any of my Arduino programs. To simplify my life, I implemented a little package to manipulate cascaded 595 shift registers which are so useful to manage arrays of LEDs.

The package allows:

  • to set On/Off all LEDs
  • to set on/off a specific LED
  • to exclusively set on/off a specific LED
  • to shift the LED patterns left/right
  • to negate the LED patterns left/right
  • to manipulate the LED patterns globally, per shift register, or for all shift registers in parallel
  • and more to come...!

I will also write a better sample code as well as a documentation soon!
