CircuitPython snakes its way to Gamebuino!

Learn Python easily – Gamebuino “Learning to code in Python is soon possible with Gamebuino!”

Python is a easy to learn language, thanks to the readability of its code and the simplicity of use. It’s an “interpreted” language, in other words you can execute it without compiling it. Not need to install another software, a simple text editor is enough! But simplicity does not mean a lack of possibilities! If it’s one of the preferred languages to learn programming (the Académie Française has chosen the Python language for the new high school reform), it also allows the creation of advanced programs, and many big companies use it for their applications: YouTube, Spotify, and even NASA claim its use! … If the final objective of Gamebuino (the creation of a game) is playful, we have put all our energy into making it a way for discovering the programming and becoming the ideal tool for learning Python.

Resurrections from Celeste – GameBoys running CircuitPython

Scott’s GameBoy orchestra sounds great! MIDI is coming from the computer into the black GameBoy pocket. CircuitPython running in the cart processes it and then queues the sounds in the GameBoy. Any notes the first GameBoy can’t play will be forwarded on to the next (blue) and then the DMG. Thanks to Playful Piano for the MIDI file. Thanks to Lena Raine for the wonderful Celeste soundtrack and to the Celeste crew for an amazing game. Support them by buying the game and soundtrack – YouTube.

Python snakes its way to LEGO and Visual Studio!

MicroPython for LEGO MINDSTORMS EV3 is here! This is a Visual Studio Code extension for programming LEGO® MINDSTORMS® EV3 using MicroPython – marketplace.visualstudio.com. 181 downloads so far 4/14/2019, appears to be the Linux port, not the “bare metal” as it’s sometimes referred to. micropython-ev3dev – GitHub, & EV3dev Python.

And there is more LEGO news.

LEGO is going full-on Python on hardware, this is the LEGO SPIKE Prime…

LEGO® Education SPIKE™ Prime is a powerful STEAM learning solution for middle school that combines LEGO bricks, coding language based on Scratch, and a programmable multi-port Hub to help every learner become a confident learner.

Read more, PDF, lesson plans, and pre-order ($329.95).

So: According to this site, the hub is running the “MicroPython Operating System”!

The spec sheet came from someone who posted this on the Facebook LEGO SPIKE page. And here is an unboxing video & parts list.

The SPIKE Prime system appears to be using the same LPF2 (Lego® Power Functions 2.0) BluetoothLE communication system that they introduced with their PoweredUp and Boost robotics gear in the last few years. This new set introduces a new hub that now has 6 general purpose ports (up from 2 in their previous LPF2 systems), and an expanded set of peripherals such as sensors and motors. … Even more exciting is that it says it’s running an embedded MicroPython OS, so hopefully they will release the Python API at some point for downloadable programs. The processor inside is, however, only specc’ed at 100MHz.

The Ultimate Game Boy Talk by Michael Steil.

The 8-bit Game Boy was sold between 1989 and 2003, but its architecture more closely resembles machines from the early 1980s, like the Commodore 64 or the NES. This talk attempts to communicate “everything about the Game Boy” to the listener, including its internals and quirks, as well as the tricks that have been used by games and modern demos, reviving once more the spirit of times when programmers counted clock cycles and hardware limitations were seen as a challenge.

Python, the fastest-growing major programming language, has risen in the ranks of programming languages in our survey yet again, edging out Java this year and standing as the second most loved language (behind Rust)… For the seventh year in a row, JavaScript is the most commonly used programming language, but Python has risen in the ranks again. This year, Python just edged out Java in overall ranking, much like it surpassed C# last year and PHP the year before. Python is the fastest-growing major programming language today… Python is the most wanted language for the third year in a row, meaning that developers who do not yet use it say they want to learn it.

Digi-Key + Adafruit @ PyCon!

PyCon 2019 returns May 1–9, 2019 to Cleveland, OH – with talks, tutorials, sprints, and more!

Big news! Digi-Key and Adafruit have teamed up for PyCon 2019 so every attendee (about 4,000!) will receive a SPECIAL EDITION Circuit Playground Express, running … CircuitPython.

This effort is to get Python on hardware to the most folks out there, at the events that bring people together.

This is just one of many efforts we’re teaming up with Digi-Key to continue to fuel all the developers from beginners to pro, using Python on microcontrollers.

What else is happening? The CircuitPython team will be running several Open Spaces sessions (as they did last year), showing how to use CircuitPython on the Digi-Key / Adafruit PyCon special edition Circuit Playground Express. We’ll have extra addons to play with also: potentiometers, NeoPixel strips, and servos. The team will be running a CircuitPython Sprint for several days to work on CircuitPython libraries and CircuitPython core code. BYOMUSB “Bring your own Micro USB” cables, we’ll have some to borrow during the sprints/sessions, as well as some USB C adapters, good idea to bring one too!

The PyCon 2019 conference, which will take place in Cleveland, is the largest annual gathering for the community using and developing the open-source Python programming language. It is produced and underwritten by the Python Software Foundation, the 501(c)(3) nonprofit organization dedicated to advancing and promoting Python. Through PyCon, the PSF advances its mission of growing the international community of Python programmers.

Scott will be leading a talk at the Python Language Summit, History of CircuitPython. The Python Language Summit is an event for the developers of Python implementations (CPython, PyPy, Jython, and so on) to share information, discuss our shared problems, and — hopefully — solve them – pycon.org/2019/events/language-summit

We will have a lot more updates, stay tuned to the Adafruit blog, Twitter, Discord, and more!
