Zackernel: an Engine for IoT

Zackernel is a tiny kernel that uses an event-driven, non-blocking I/O model like Node.js. It is written in C++11, to use lambda expressions.

Now, Zackernel works on the following environments:

• Arduino

Zackernel needs the following software:

• Download zip file from Vlpp for Arduino, and install it Sketch > Include Library > Add .ZIP Library. (Documents how to install the library)
  • Thanks for Original Vlpp for Arduino and Original Vlpp

  // calculate something while flag is true with calling other tasks
});

bool flag = true;
zDoWhile([&] {
  // calculate something once and while flag is true with calling other tasks
}, [&] { return flag; });

int i;
zFor([&] { i = 1; }, [&] { i < NUM; }, [&] { i++; }, [&] {
  // calculate something while i < NUM with calling other tasks.
});
