Arm: “Panfrost is now the GPU driver for the Linux community”

Arm Panfrost Linux

Arm is now saying that “in effect, Panfrost is now the GPU driver for the Linux community” after having extended and expanded the collaboration with Collabora for the development of the open-source Panfrost driver for Arm Mali GPUs, following their first official collaboration in the fall of 2020. Arm goes even as far as to claim that “through the Arm and Collabora partnership, device manufacturers can confidently choose SoCs containing a Mali GPU regardless of the software operating system (OS) and graphics middleware… delivering a high-quality open-source Linux implementation which can be used in their products”. Collabora confirmed the new partnership saying Arm will be instrumental in getting Vulkan support in Panfrost alongside the existing OpenGL and OpenGL ES implementations. Going forward that means SBC vendors will have no excuse for not getting 3D graphics acceleration working on Linux with Panfrost when using an Arm SoC with a recent Mali […]

smolOS brings a Linux-like command line interface to ESP8266 microcontroller

smolOS command line ESP8266

smolOS (pronounced small OS) is an open-source, lightweight MicroPython program that implements a POSIX-style (Linux-like) command line interface for the ESP8266 WiFi microcontroller. Krzysztof Jankowski (w84death) designed smolOS to be easy to use, allowing the listing and removing of files and also including the smolEDitor which, as its name implies, is a simple text editor. There are currently eight commands with the familiar ls, cat, and rm, plus ed to launch the text editor, welcome to show the welcome screen above, cls to clear the screen, mhz to set the processor speed to 80 or 160 MHz, and info to display some hardware and software information. The project looks to be a work in progress, and the developer highlights the editor is at the alpha stage of development, so more features may be implemented over time by Krzysztof himself or by the community of developers. I also assume other microcontrollers […]

PiccoloBASIC – A BASIC interpreter for the Raspberry Pi Pico board

Raspberry Pi Pico BASIC

PiccoloBASIC is an open-source BASIC interpreter for the Raspberry Pi Pico development board that’s based on “uBASIC: a really simple BASIC interpreter” by Adam Dunkels and relying on Arm’s LittleFS fail-safe filesystem for microcontrollers. If my memory serves me well, my first computing experience was at school using a Thomson TO7 computer that we programmed with BASIC. I don’t think the language is still used in practical applications, but we can still see some BASIC projects pop up from time to time such as a BASIC interpreter for the Arduino Zero boards. Gary Sims, owner of the Gary Explains YouTube channel, has now ported a BASIC interpreter to the Raspberry Pi Pico.   The project is still work in progress, but currently implemented features include: Let, if, print, for, goto, gosub String variables (let z$=”hello”) Floating point numbers and variables (let z#=1.234) Builtin functions [zero, randint, not, time] Sleep, delay, […]
