UPDATED GUIDE: MP3 Playback on RP2040 with CircuitPython #AdafruitLearningSystem #Adafruit @adafruit
Play some tunes on your RP2040 using I2S!
Compressed audio can be a nice alternative to uncompressed WAV files, especially when you have a small filesystem like that on many CircuitPython boards, as WAV files get sizeable quite quickly. You can listen to a much longer playlist with CircuitPython, at even higher quality, using the built in I2S MP3 playback capability!
The new Pico I2S MP3 page explains I2S and provides examples of I2S breakouts. It then walks you through wiring up an I2S breakout to your Raspberry Pi Pico, and provides code examples for playing tones, WAV files, and MP3 files.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
