Using a Raspberry Pi Pico as a cheap multi-channel DAC for pitch CV
Hi all, I'm making a Eurorack sequencer module with 4 pitch CV outputs (NOT audio) and I've noticed that DACs are kind of a pain due to being expensive, SMT-only & still requiring buffering with op amps. I figure that a good alternative would be to buy a Raspberry Pi Pico for $4 which will give me 8 PWM outputs that I would then hook up to an output stage like the one in the europi (shown here: https://github.com/Allen-Synthesis/EuroPi/blob/main/hardware/EuroPi/schematic/europi_schematic.pdf)

What is your favorite open source eurorack module? And the best documented?

Is it really necessary to put opamps in front of my ADC inputs?
Up until now I've been using the analog input stage from the EuroPi schematic as my model for a CV in. You can see it here:

Easiest/cheapest way to get multiple (9-12) analog cv outputs (0-5V volt) from a single microcontroller/arduino
There is no super cheap way to get a lot of analog outputs from an MCU. Filtered PWM is your best bet for cost effectiveness (I recommend looking at the EuroPi from allen synthesis : https://github.com/Allen-Synthesis/EuroPi). Otherwise if PWM doesn't work for you, you'll need to look into DAC chips. The MCP4728 is a good spot to start, it's 12-bit and has 4 channels: https://www.adafruit.com/product/4470. Since it's I2C controlled you can have multiple of them on one bus. Maybe looking into a 16 channel PWM driver for a lot of outputs: https://www.adafruit.com/product/815. Hope this helps!

My Raspberry Pi Pico based Eurorack module has a new software release!
The project is completely open-source and open hardware, and the contributors together have made this big list of scripts that you can run using a menu system!

My reprogrammable DIY module (EuroPi) has just had a new free software release!
The project is entirely open-source but I do also sell the Panel+PCBs on my site!

Firmware hacking with Uncertainty
EuroPi Turing Machine script is feeding the Uncertainty cv input with pulse 1 opening an envelope on Maths for voice 1 & 2, pulse 2 opens the second Maths envelope for sub osc voice 3. A little delay added for texture. That's pretty much it!

A Question, for anyone that knows how MI firmware code works
The patch.init() is still a great way to start, but you could save some money ditching the audio i/o and build yourself an EuroPi. However, that requires DIY, obviously.

Raspberry Pico Badger: Hardware Features and OS
The recommended way to programm MicroPython on the Raspberry Pico is to use the Thonny IDE. Accessing the Badger with reveals the following file structure:

Abstract Classes in Python
Personally, I like to debug and step through code to see where I went wrong so I'm going to paste the code into my Thonny IDE. I like Thonny for small code challenges like this because it doesn't require setting up a whole project just to run and step through code.

Ask HN: Do you know any good coding platform for education?
Thonny is designed speciffically for that purpose https://thonny.org .
For beginners the main advantage is the easier install and maintainance, and the less intimidating/cluttered environment.
IMHO it makes some decent tradeoffs, and it is an onramp for students evolving to VSCode or PyCharm when they feel ready.

Macropad with KMK
I use the serial console with a tool like Thonny to debug KMK/CircuitPython code on my device. running something like import main; main.keyboard.go() usually prints a useful error message.

Help me Please
If you think you need an IDE then Thonny is a good one for beginners. It does more than a simple text editor, some of which you won't use initially, but it is more to learn on top of learning python.

Alguem sabe um editor de codigo leve para python?
Usa o thonny. É muito bom e leve.

What’s an free bare bones IDE for Python that works smoothly out of the box?
VSCode is good but I wouldn't describe it as "barebones". I recommend Thonny. It's a Python IDE specifically for beginners.
-
There's just TOO MUCH material!!!
All you really need to learn python is just an installed python interpreter, the command line and a text editor like Notepad, but that's a bit too minimal perhaps. There are things called IDEs (Integrated Development Environment) that bundle up tools such as an editor, build tools and a debugger into one package. I think that a full-blown IDE is overload for a beginner with too much to learn that isn't actually python. If you want to use an IDE try something like Thonny which is aimed at beginners. When you get some experience try other IDEs and Jupyter.

Now, NiceGUI has a build-in persistent user/session based storage.
Maybe a goofy question, and definitely unrelated to the post topic, but: I’m using Thonny to learn Python: can I use NiceGUI with Thonny?
