WARDuino: a dynamic WebAssembly virtual machine for programming microcontrollers

Abstract

It is extremely hard and time-consuming to make correct and efficient programs for microcontrollers. Usually microcontrollers are programmed in a low level programming language such as C which makes them hard to debug and maintain. To raise the abstraction level, many high level programming languages have provided support for programming microcontrollers. Examples include Python, Lua, C# and JavaScript. Using these languages has the downside that they are orders of magnitude slower than the low-level languages. Moreover, they often provide no remote debugging support.
