Raspberry Pi

  • Raspberry Pi marks 2nd birthday with plan for open source graphics driver

    That “blob” is the closed source driver code that the Pi requires today. “In common with every other mobile graphics core, using the VideoCore IV 3D graphics core on the Pi requires a block of closed-source binary driver code (a ‘blob’) which talks to the hardware,” Upton wrote. “Our existing open-source graphics drivers are a thin shim running on the ARM11, which talks to that blob via a communication driver in the Linux kernel. The lack of true open-source graphics drivers and documentation is widely acknowledged to be a significant problem for Linux on ARM, as it prevents users from fixing driver bugs, adding features and generally understanding what their hardware is doing.”

  • A birthday present from Broadcom
  • Get Quake III running on Raspberry Pi using Broadcom’s open-source GPU drivers, earn $10K

    Broadcom has released open-source drivers and documentation for the graphics processor that’s used in the Raspberry Pi microcomputer, among other devices.

    “To date, there’s been a dearth of documentation and vendor-developed open source drivers for the graphics subsystems of mobile systems-on-a-chip (SoC),” Eben Upton, a Broadcom technical director and Raspberry Pi Foundation cofounder, wrote in a blog post. “Binary drivers prevent users from fixing bugs or otherwise improving the graphics stack, and complicate the task of porting new operating systems to a device without vendor assistance.”

  • Broadcom Open-Sources VideoCore IV 3D Graphics Stack

    In celebrating two years that Raspberry Pi has been around, Eben Upton has announced today that they are open-sourcing their OpenGL ES 1.1/2.0 graphics stack for the Broadcom VideoCore IV 3D graphics subsystem and it will help the Raspberry Pi with having a truly free graphics stack.

  • Android for All: Broadcom Gives Developers Keys to the VideoCore® Kingdom

    The community of open source mobile developers around the world are a vocal bunch – and here at Broadcom we’ve heard their call.

    To date, there’s been a dearth of documentation and vendor-developed open source drivers for the graphics subsystems of mobile systems-on-a-chip (SoC). Binary drivers prevent users from fixing bugs or otherwise improving the graphics stack, and complicate the task of porting new operating systems to a device without vendor assistance.

    But that’s changing, and Broadcom is taking up the cause.

  • A Nicely-Built 40-Core Raspberry Pi Cluster

    Raspberry Pi super-computing clusters have been attempted before, but usually they don’t turn out as nice as this new one that’s comprised of 40 Raspberry Pi boards inside of an acrylic chassis.

  • Teachers panicking over new computing curriculum

    Raspberry Pi director of Educational Development Clive Beale questioned whether the DfE is doing enough. He said, “I’m really worried it hasn’t been taken seriously enough.”

  • Raspberry Pi: giant hacks for a tiny board

    Usually there are two ways to look forward to buy a Raspberry Pi: first, think about a strange thing to make, and then go to the website; or second, buy the Raspberry Pi board having no idea of what you are going to do with it. Usually, I buy things and only after that I go through the Internet in search of inspiration and creative use cases for my new toys. That was the case with my first Raspberry Pi board: everyone seems to be able to put together his tiny PC with some parts (monitor, mouse and so on), a CPU and a lightweight Linux distribution, but what can we do that is totally crazy, mind-blowing and problem-solving?

PicoScope

  • Embedded World: PicoScope gets Linux software

    Pico Technology has released a beta version of the PicoScope 6 oscilloscope software for Linux.

    This is intended to support the use of Linux in the scientific and educational fields.

    The PicoScope 6 application runs on a PC to create oscilloscope, FFT spectrum analyser and measuring device functions.

  • Pico scopes now run Linux

    Users can save captures for offline analysis, share them with other PicoScope for Windows and PicoScope for Linux users, or export them in text, CSV and Mathworks MATLAB 4 formats. The only additional hardware needed is a USB oscilloscope.

  • A USB scope for Linux fans

    USB oscilloscopes are popular – only that the marketable supply is focused almost exclusively to Windows platforms. Pico Technology now redeems the growing flock of Linux users by offering such a software that runs under their preferred operating system.
