Create your own libraries

[nhannguyendung086]

Does anyone know how to create and use a library (not importing external libraries) in PlatformIO for Arduino programming?

Writing Libraries - free eBook

I’ve written up a small eBook thingy on the subject of writing libraries for use with the Arduino IDE and PlatformIO. It’s available here: https://github.com/NormanDunbar/WritingLibraries/releases/latest. That URL will always take you to the very latest release, in case I have to make changes. The eBook covers the following: How to write a small “pure” Arduino library. This is named digitalPin and uses the Arduino language throughout. It can be used in the Arduino IDE and also, in PlatformIO…

Cheers,
