The Pi4J Project

Should we bump the minimum supported Java version in Pi4J V2? At this moment, it is built with Java 11 as the target. This means we miss out on many Java language and runtime improvements in newer versions. Newer versions (22) make, e.g., calling C code to interact with the GPIOs easier with JEP 454: Foreign Function & Memory API.

Blog: "Maven Downloads". How many times are the Pi4J libraries downloaded from the #Maven repository? https://lnkd.in/eUsRTDpM

I want to share my last weekend project: "My first experiments with #Java and The Pi4J Project on a Raspberry Pi Compute Module 4". Of course, it works, as Java runs everywhere ;-) And thanks to the step-by-step by Jeff Geerling, burning the OS to the eMMC on the Compute Module is a piece of cake! The video explanation is available here: https://lnkd.in/epQgx-7t. The blog post with more info is here: https://lnkd.in/eJciJ5gC #JavaOnRaspberryPi - #waveshare - Azul

Are you ready for The Java Community - Devoxx conference next week? Join Ronald Dehuysser and me for a workshop on Monday where we will schedule "virtual" beer brewing tasks with JobRunr, The Pi4J Project, Azul, and Raspberry Pi! The test setup is ready, and the code is on GitHub waiting for you. Now we only need the "conference gods" not to mess up our demo ;-) And yes, this setup is suffering from the #TooManyWiresException. More info on https://lnkd.in/e4DFCJNF #JavaOnRaspberryPi

#Pi4j has just released a new version 2.7.0! This release brings quite a few fixes and makes development on your ##java workstation easier as it detects your environment and doesn't load native libraries. Especially great for all those #Spring devs out there! #RaspberryPi Got check it out at:

#Blogged + #Video: From time to time, I see questions about signed versus unsigned values and how this can be confusing in #Java. Based on a chapter of my book in which I experiment with bits, bytes, and an LED segment display, I wrote a tutorial blog post with a code demo video. Watch the video on YouTube: https://lnkd.in/eECfv6zU. Or read the blog post with more info here: https://lnkd.in/eaSSHqvg The Pi4J Project #tutorial #javaonraspberrypi

I'm back from holiday and found this new edition of German Java Magazin in the box. It contains my interview with Tom Aarts and Robert von Burg about the new developments in the The Pi4J Project for the Raspberry Pi 5 and other ongoing improvements. #JavaOnRaspberryPi. https://lnkd.in/ejMCSXNa

Excited! I will be on The Java Community - Devoxx stage twice in Antwerp in October! Together with Ronald Dehuysser, we will demo hands-on JobRunr with #JavaOnRaspberryPi. The second one is even more special as Vik, my 14-year-old son will co-present and compete with #VirtualThreads to prove who is the best piano player, (young) man versus machine! You can see some of it already in action in our app, MelodyMatrix, here: https://lnkd.in/ggsRNqGj. #kotlin #javafx #midi The Pi4J Project #devoxx

My "Java and Technology" YouTube #Playlist now contains exactly 50 videos! Check it out on https://lnkd.in/e9SeXK9B to learn more about #Java, #JavaFX, The Pi4J Project, conference talks, #htmx, what I learned about #OpenJDK at Azul, fun projects with #JavaOnRaspberryPi, games created with #FXGL, and much much more. Have fun watching, and subscribe for more to come...

V2.6.1 of Pi4J got published with some minor fixes: gracefully handle UnsatisfiedLinkError on newAutoContext when not running on a Raspberry Pi + clean up of logs in MockI2C.java. Read more about it on https://lnkd.in/eH4kZet2
