#CircuitPython controlled pocket operator. KB2040 is setup as a midi in device. Reason is sending out four midi tracks on four different midi channels. Each button/synth voice on the pocket operator is assigned a midi channel. When a note on message comes in on the corresponding channel, the button is triggered via GPIO through a mosfet. The DAC is controlling the pot that is used for notes for some of the synth voices #pocketoperator

And just like that we have a functioning clock! currently running on a propmaker RP2040 but I will probably have to move over to something WiFi enabled before long #pcb #electronics #maker #RP2040 #RaspberryPi #jlcpcb #circuitpython @adafruit

@b0rk relatedly, in #CircuitPython we've identified a small set of codes to support for the purposes of managing a built in terminal. Because we're extremely constrained on code size, it's a very small list. Clearing & positioning are about it. Plus scrolling when you reach the bottom of the screen. I think someone's adding scroll regions (set by some escape code or other) for more powerful microcontrollers that can accept the increased code size that requires. Similarly, just a few input escape sequences are handled, like left/right/up/down arrows. This is enough to be useful, there's a full screen editor implemented in Python though! https://learn.adafruit.com/circuitpython-text-editor-on-the-go

I'm tyring #circuitpython on an #esp32 Yesterday I wasn't having any problems making http connections, but today, everything is failing with timeouts or EINPROGRESS or whatever.
The code was working consistently before. The wifi is fine. I can fetch data from my laptop.
I don't get it. FWIW, I"m using the adafruit_requests library.

I've uploaded the [iffy] #CircuitPython library I made to https://github.com/8086net/CircuitPython_UARTboot although I imagine those with the hardware to do UART boot on the #RP2350 will already have a way to upload firmware.

Got things wired up and wrote some quick demo code in #circuitpython using a vectorio circle, I’m mapping the analog input from the potentiometer to the circle x and y position so that the circle follows the pot’s wiper. It’s a log pot so there’s some accounting for that in the code. Luckily I’ve done a few round display projects in the past year so I could take from the math done by past me

I've hacked together a CircuitPython library to UART boot the RP2350. The two bin files it's uploading just cycle through the LEDs in different directions.
I still have no RUN pin so I'm using one of my USB Power Switches to power cycle the board.

#CircuitPython #Makers, I've heard Mu is being discontinued this year. I switched to PyCharm CE for my PhysicalComputing course last semester & it worked great, after the daunting (for newbies) setup & tio configuration. The code completion & error handling, plus adding CircUp, made things quite smooth. Is that still the recommended platform, or is there something else I should have on my radar? Thanks!

The ch32v208 looks very interesting too. Enough RAM to potentially run #CircuitPython or #LUA but has some tiny packages. Could potentially replace the SAM21 in my toolbox...
New blog post - The Return of The CircuitPython Show: https://www.paulcutler.org/posts/2024/12/the-return-of-the-circuitpython-show/ #circuitpython #circuitpython2025
Paul Cutler · The Return of The CircuitPython ShowWhen I blogged earlier this year that The CircuitPython Show was over, I really thought it was over. But with the talk of #CircuitPython2025 kicking off, I started to give the podcast some thought again. And while I thought I had talked to most of the community members I wanted to talk to, there were still a few I hadn’t reached out to yet.
But where it really intrigued me, was what if it wasn’t just an interview show and I sprinkled topic based episodes in as well? I quickly brainstormed half a dozen ideas and realized there was more to do yet. I reached out to a number of potential guests and the reponse was overwhelmingly positive.
I teach separate courses in #SwiftUI and #CircuitPython on microcontrollers (Adafruit CircuitPlayground Bluefruit & Raspberry Pi Pico W). Over break I wanted to get some embedded Swift running on the Pico to bridge these works. The couple hours I’ve spent reading & watching videos suggests this is a bit of a gnarly setup - no Xcode, a new set of commands. Can anyone suggest a fast-path to quickly get up with #EmbeddedSwift? Does this seem ready for class/project use?
Day 18 of #makeradvent and today I have started hacking the IKEA Vindriktning air quality sensor with #circuitpython and an #esp32 https://youtu.be/A0qONiRQqoY
Robot Maker Yes! It’s arrived. Can’t wait to get stuck into this.

today i photo'd the rp2350 #circuitpython video synth project. here is a quick demo video i took showing off with animations (its final form will be a gif changing between the 3 animations). the synth uses a PDM mic for fft, which has been a project goal that i've had for a while
this project was hard but i'm really pleased with how it came out. it uses a raspberry pi 5 with the m.2 hat to build a media server. #circuitpython / blinka code interfaces with an nfc breakout so that you can use an nfc card to play movies
Adafruit Learning SystemNFC Raspberry Pi Media PlayerYou can build a movie library using a Raspberry Pi 5, Adafruit's NFC breakout and NFC cards. This project runs Python code with Blinka, the CircuitPython compatibility library for single-board computers running Linux, to create a script that allows you to use NFC cards to launch movies in the VLC media player.
Just finished a complete overhaul of the internals of my ever popular lightsabre make which was broken in several ways and had multiple wires close to breaking. All resoldered and hot glue strain relief applied (after testing all parts together). New USB breakout fitted. Now to reassemble with newly printed parts (in PETG) which hopefully will handle the abuse this gets at public events. #maker #circuitpython
