Practical mruby/c firmware development with CRuby

A talk of RubyKaigi 2019 in Fukuoka. Writing mruby/c firmware applications is like writing mrbgems. You need to make some C functions and mruby wrapper of them in order to handle peripherals like sensor, flash memory or BLE. Easy to imagine it's hard to develop for a team in a situation of TIGHT COUPLING, right? I will talk about some tools, mrubyc-test and mrubyc-debugger, which I made with CRuby for testing and debugging to keep our team slack coupling.

Firmware programming with mruby/c

We have a new choice to write firmware for microcomputers(microcontrollers). It's mruby/c. This talk shows how to introduce mruby/c firmware programming. And besides, my actual IoT project for Japanese Sake brewery will be described. Since mruby/c is still a young growing tool, you will know there are several(many?) things you can help it to become better.

Making IoT device with Ruby

I made an IoT system to manage the brewing temperature for Asahi Shuzo (Izumo city) with Ruby. I will talk about the value of Ruby on-the-spot of IoT, and about the way how a very ordinary Rubyist got to be able to handle microcontroller.
