In my presentation, I will show how data-flow programming can be used for software development of small devices. The effectiveness of the proposed method is demonstrated with a microcontroller implementation in mruby/c.

In IoT programming, we want to focus on the flow of data generation and processing. This is data flow programming, also known as the Node-RED development environment.

Data flow is processed asynchronously. I will explain how to implement this asynchronous processing in a reasonable manner using mruby/c and demonstrate its operation on a real microcontroller.
