Eric Anholt gave a great talk about building an open source OpenGL driver for the Raspberry Pi at Linux Conf Auckland 2015 this week. One of the challenging things with using the GPU on the Raspberry Pi is that it relies on a closed source driver so using it to its full potential can be tricky. However Eric talks about how his experience working on drivers for Intel’s graphics processors is helping him write an open source OpenGL driver for the Pi. The talk goes into a lot of advanced details with writing graphics drivers, like how to compile and optimize OpenGL code into instructions that the GPU will execute. Overall it looks like great progress is being made and in the not too distant future it will be much easier to port OpenGL and other 3D acceleration tools to the Raspbery Pi!
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.
