eLua stands for Embedded Lua and the project aims to introduce the programming language Lua to the embedded software development world. Lua is the perfect example of a minimal, yet fully functional language. Although generally advertised as a "scripting language" (and used accordingly especially in the game industry), it is also fully capable of running stand-alone programs. Its limited resource requirements make it suitable to a lot of microcontroller families.
The aim of the project is to have a fully functional Lua development environment on the microcontroller itself, without the need to install a specific toolchain on the PC side.
