Tutorial

This tutorial introduces the ik language and toolchain by building real, flashable programs. It assumes you have written code before and have a basic idea of how a microcontroller toggles a pin, but it does not assume any prior AVR assembly knowledge.

Work through the pages in order. By the end you will have built the compiler, blinked an LED, walked the core of the language, pulled in the standard library, and handled a hardware interrupt.
