Mruby—rapid IoT software development language

Embedded systems are systems in which hardware and software are closely linked. In the embedded system, the software controls the hardware. We focused on Ruby which is an object-oriented programming language and scripting language to improve development efficiency of embedded systems. We developed mruby which applied Ruby for embedded systems, and this overview is described in this paper. mruby provides the real-time and hardware access functions required by embedded systems.
