All you have to do is define the branch from which to build and the user modules to include and… Hey Presto! there’s your personal firmware for you to download.
If you’re new to the whole IoT frenzy and ESP8266 in particular I recommend the following two tutorials for starters:
- ESP8266 Quick Start by Peter Jennings, has got project tutorials as well
- Getting Started with ESP8266 by Open Home Automation, has got project tutorials as well
- squix78 also regularly blogs about NodeMCU and ESP8266 with cool projects
If you want to build the firmware yourself but don’t want to set up the entire tool chain on Linux (or a Linux VM) you might want to try my Docker NodeMCU build. It offers all the comfort of hacking on NodeMCU on your preferred platform combined with a one-click build in the Linux Docker container.
