This is the recording of the live stream with @frankdelporte and Nick Gritsenko. They talked about the Foreign Function and Memory (#FFM) API introduced in Java 22 and how it was used to create a new plugin for the Pi4J library. This will help bring #Java based electronics programming to many more boards and simplify the Pi4J project.
Pi4J is now part of the Commonhaus Foundation @commonhaus_fdn ! Still "paperwork" to do, but we are now part of a bigger group to ensure continuity for the project!

Join me today, at 15:00 CET, online for the #jChampions Conference for my talk: "The Wait is Over: Foreign Function & Memory (FFM) API brings modern Java to the Raspberry Pi." Let's have some fun with #JavaOnRaspberryPi while discovering how the FFM API brings a new way to interact with memory and external libraries with #Java.
Ever since I started my #JavaOnRaspberryPi journey in 2019 for my book "Getting Started with Java on the Raspberry Pi", I've been fascinated with these tiny, inexpensive computers.
For 2026, I've set one of my goals to experiment with different types of Single-Board Computers (SBC). These boards are available with different processors based on x86, ARM, and RISC-V.
In this blog, I compare these processors:

This year, I spent a lot of time learning about the changes the Foreign Function and Memory API is bringing to Java and, more specifically, to @pi4j. I spoke about it at conferences and JUGs, and a full article is now available on the JVM Advent website. "The FFM API: How OpenJDK Changed the Game for Native Interactions (And Made Pi4J Better!)"

The Pi4J project is a Java library that allows you to control the GPIO pins and electronic components connected to a Raspberry Pi with pure Java code. It removes the complexity of using native libraries and the Java Native Interface (JNI), allowing you to focus on your application logic. In the Java Advent of 2020, I published “Light up […]
