#rp2040 #microcontroller

Video of a I2C display showing an animation of a donut spinning. Shortly, the camera pan to the left, revealing a microcontroller (a YD-RP2040 by VDD-GND Studio) and how the screen is connected to the microcontroller. The camera then zoom in, focusing on the microcontroller and pan back to the display still showing the donut spinning animation. The video then ends.

I made a little 3d-printable case for my “qtpy_synth” test board to help me play with CircuitPython synthio (and Arduino Mozzi). It works pretty well, I like it better than the standoffs I originally started with. And now can have some cool matching 3d-printed knobs! https://www.printables.com/model/757087-case-for-qtpy_synth-circuitpython-synthesizer

Hello,

Has anyone successfully implemented Nintendo Switch's :nintendo_switch_logo: JoyCon analog sticks to QMK firmware for mechanical keyboards? Any examples for wiring and firmware would be appreciated.

I'll use along with Splinky (Open source hardware, powered by #RP2040 , but 1:1 pin compatible with classic Atmega32u4 Sparkfun Pro Micros)

Chiptune time!
This is a polyphonic, multitimbral DDS (Direct Digital Synthesis) library for Raspberry Pi Pico.

It has several waveforms, ADSR, and a sequencer supporting up to 8 channels.

Demo video: https://www.youtube.com/watch?v=MUQ7loauSa0

Source code: https://github.com/TuriSc/Pico-Sequencer-Synth

It's my C port of a C++ demo by Pimoroni, adapted to output audio via I²S or PWM, and with a few other tweaks. All bundled up in a module.

Raspberry Pi Compute Model 5 is coming in 2024, along with an updated RP2040 microcontroller, which will likely have more RAM and maybe more GPIO. https://www.hackster.io/news/eben-upton-hints-at-an-rp2040-successor-promises-a-raspberry-pi-compute-module-5-in-2024-ec331994aca3 #RaspberryPi #RaspberryPiCM5 #RP2040

Regarding #libsibo, I'm trying to decide on the way forward for the project.

Currently it's in #Arduino C, so there's the odd class, but it's mostly regular C. It'll run on an Uno, ESP32, or a Pico/RP2040.

I've wanted to drop the ESP32 support for ages. But I'm wondering about dropping Arduino support and switching fully to the #RP2040 SDK. For the Uno, I can just maintain the old .INO file for basic functions.

If I go C, I'll have to refactor the classes. But is going full C++ a good idea?
