Running Erlang and Elixir on microcontrollers with AtomVM

A long time ago it was possibile to run Erlang on a MS-DOS PC in less than 640 KB. Nowadays PCs have gigabytes of RAM and computing is also ubiquitous. However microntrollers found in IoT devices have the same amount of memory as an old MS-DOS era PC. Erlang and Elixir might be the answer to some of the IoT challenges, but BEAM cannot run on such systems. AtomVM tries to fill the gap and overcome this limitation.


Explaining how Erlang and Elixir are suitable for embedded purposes, and what AtomVM is and how it works.


Anyone interested in using Erlang/Elixir on microcontrollers (or generally in embedded devices). AtomVM is also a good simplified implementation of an Erlang VM, useful to anyone who wants to learn how an Erlang VM works.
