In “The MagPi Magazine” #93 and #94, published by the Raspberry Pi Foundation, you can find two articles which describe how you can get started with Java, Maven, Visual Studio Code and Pi4J on the Raspberry Pi. To make everything even more clear, I created a step-by-step video on Vimeo which shows everything which is described in those two articles.
Using the Java library I created (see previous post), it was a piece of cake to create a JavaFX UI on top of it! Source The sources are part of the GitHub project which contains all the other examples, scripts, readmes and a lot more which are used in the book to explain Java, JavaFX, Maven, Raspberry Pi GPIO’s…
Next step in my book progress, is getting more into the details of hardware components. And as always starting with the smallest most-used ones: resistors! To be able to fully document this for the book and create a demo application, I started again with creating and sharing a Java library.
The best way to understand and learn something new, is to document it yourself. That’s what I’m doing in every step for my book-in-progress. And to fully get the pinnings and headers of the different Pi-boards, I decided to gather all info into a Java library with different enums to be able to auto-generate some content for the book and use in a few different example applications.
My very first open source JavaFX library is now available in the Maven repository! A small step for mankind, one giant leap for myself ;-) While working on Java example projects for my book “Getting started with Java on Raspberry Pi”, I needed a way to visualize a LED number display as used in electronics projects.
I prefer a Java app above a web app, because starting a new “modern” web development requires you to pull a bunch of dependencies and a lot of files before you can start. While Java just needs the JDK and one Java file, even on a Raspberry PI (as described in PiJava - Part 2).
