The Wayland compositor API gives us a way to present the HVS to applications in a standards-based way. Over the last year we’ve been working with Collabora to implement a custom backend for the Weston reference compositor which uses the HVS to assemble the display. Last year we shipped a technology demonstration of this, and we’ve been working hard since then to improve its stability and performance.
The “missing piece” required before we can consider shipping a Wayland desktop as standard on the Pi is a graphical shell. This is the component that adds task launching and task switching on top of the raw compositor service provided by Wayland/Weston. The LXDE shell we ship with X on the Pi doesn’t support Wayland, while those shells that do (such as GNOME) are too heavyweight to run well on the Pi. We’ve therefore been working with Collabora since the start of the year to develop a lightweight Wayland shell, which we’ve christened Maynard (maintaining the tradition of New England placenames). While it’s some distance from being ready for the prime time, we though we’d share a preview so you can see where we’re going….
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
