8/10/2023 0 Comments Raspberry pi 4 ubuntu desktop![]() In the short term, many key libraries that Raspberry Pi HATs rely on, such as RPi.GPIO, assume the use of sysfs-gpio. In the long term, this is a significant improvement in both security and application management as it prevents two applications from trying to access the same pins simultaneously. Similar to the fkms to kms transition (do you remember which is which?) lgpio gives the kernel control of the GPIO pins rather than letting libraries interact with them directly. ![]() This release we’ve also made a big change behind the scenes to move Ubuntu from relying on the now deprecated sysfs-gpio to an lgpio solution. Preparing for the future: transitioning the GPIO interface This includes rshell and mpremote for remote development and Thonny, a mini Python IDE for beginners.Īgain, Dave’s blog has everything you need to get started. For industrial and IoT use cases, porting processes over to the Pico could deliver a significant advantage.Īs a microcontroller, the Pico isn’t powerful enough to run a full operating system, but with languages like MicroPython you can run Python code directly on the hardwareįor Ubuntu 22.10 we’ve included the full MicroPython developer stack in the Ubuntu repositories, enabling you to apt-install all the development tools you need to get started with Microcontroller development. It’s smaller, cheaper and uses less power than a Raspberry Pi Zero 2 W. If you’re struggling to get your hands on a Raspberry Pi, now might be a good time to start experimenting with the Raspberry Pi Pico W. Remember to bring your reading glasses!įor more information on these demo projects check out Hyping Pixels on Dave’s blog. Whilst it’s not the ideal way to experience Ubuntu Desktop, it’s certainly a novelty to see it running on such a small screen, with touch support. It means that with Ubuntu 22.10, you can now use the Hyperpixel display range, the Raspberry Pi Official Touchscreen Display and the Inky eInk series out of the box. This migration has made supporting display HATs easier since Ubuntu can now treat them as a standard display with only minor tweaks. Get hyped for Hyperpixelsīehind the scenes, the graphics stack for the Raspberry Pi has undergone a significant transition, moving from fake KMS (or fkms) which involved closed-source firmware running on the GPU separately from the Linux kernel, to the open-source ‘full’ KMS (or, confusingly, just kms) which puts the Linux kernel directly in charge. ![]() We’ll run through these highlights and more in the rest of this post, but as usual Dave ‘Waveform’ Jones, our resident Raspberry Pi engineer at Canonical, has put together a suite of detailed blog posts to provide additional backstory to each feature. In addition we’ve worked hard to support the Raspberry Pi’s even smaller cousin, the Raspberry Pi Pico W with the full MicroPython stack now available in the Ubuntu repositories. In this release, Ubuntu now supports a range of embedded display HATs as well as under-the-hood improvements to the GPIO stack as we transition from RPI.GPIO to lgpio (more about that later). When it comes to Raspberry Pi support, the theme of Ubuntu 22.10 is definitely embedded devices.
