Welcome to the world of embedded programming using the Lua language and the E2FL/Callisto processor module.  Using Callisto to learn to build embedded applications such as robots is quick, intuitive and fun. The only things that you’ll need to get going right away is an interest in some curiosity, and a serial terminal application.  In the next few steps you’re going to connect Callisto to the computer, and test it by writing some quick code to light some LEDs!
