A new version of CircuitPython is near final release. Version 8 RC 1 was released today (yesterday, actually, but it wasn’t officially documented until today). I’m interested because now there’s an official CircuitPython released specifically for the Raspberry Pi Pico W ( https://circuitpython.org/board/raspberry_pi_pico_w/ ). I’m starting with one of my Pico W boards, and then moving around to all the devices that currently run 7.3.3. So far nothing has leaped out as a problem, but these are very early days. I know that WiFi works, but I don’t know if Bluetooth is working or not.

One application I’ve been tweaking along the way is an automatic quote displayer that queries the Adafruit quote server and prints it out. The response comes back in JSON. The original code, written for CP 7, only printed the response out in a raw format. This version parses the JSON and line wraps long quotes to less than 80 columns. Here’s a typical output.

...   Injustice anywhere is a threat to justice everywhere. - Martin Luther King, Jr.   I never am really satisfied that I understand anything; because, understandit well as I may, my comprehension can only be an infinitesimal fractionof all I want to understand. - Ada Lovelace   Adversity is revealing of character. - Unknown   The most exciting phrase to hear in science, the one that heralds new discoveries,is not 'Eureka!' but 'That's funny...'. - Isaac Asimov   The whole point of getting things done is knowing what to leave undone. - Oswald Chambers...

And here’s the code.

As they say, more to come.
