These arduino libraries include a set of task based components that do non-blocking IO (no calls to "delay" or "while" loops) A central tasklist runs all tasks in a loop. Each task indicates whether it is runnable and determines what it should do when running by means of a task state.

Currently the following components are available:

• Hardware serial (no block on write -> tx buffer)
• 4 bit LCD display (HD44780, no blocking wait between commands -> one command at a time)
• 128x64 graphic LCD (ks0108 under development)
• Ethershield (WIZnet w5100, enc28j60 under development)

Since each task quickly returns to the mainloop without blocking, the arduino remains responsive and won't miss e.g. IO pin signals.
