circuitpython-tricks / larger-tricks

These are larger tricks that are too big to fit in the circuitpython-tricks page.

This directory contains a fairly un-ordered list, but here are the main tricks.

Display and images

  • emoji_flipper - demonstrate how to use displayio and spritesheets

  • fireworks_sprites - demonstrate using displayio spritesheets to do animation and simple phyics engine

  • dvdlogo_vectorio - demonstrate vectorio to display bouncing DVD logo

  • vectorio_rotate_example - some vectorio tools to rotate & scale vectorio point sets

Audio playing

  • audiomixer_demo - show how to use audiomixer to play multiple WAVs at different volumes

  • pidaydrummachine - show use of keypad and audiomixer to make a drum machine

  • beatfader - using audiomixer to fade between different WAVs

  • beatfader_i2s - using I2S DAC and audiomixer to fade between different WAVs

  • i2s_sdcard_pico - how to set up I2S audio out and SD card reading on Raspberry Pi Pico RP2040

  • wavmix_s2mini_i2s_sd.py - play multiple 44.1 kHz WAVs from SD card to I2S DAC on ESP32-S2, like beatfader

MIDI

  • midi_forward - simple USB MIDI to Serial MIDI forwarder using adafruit_midi and usb_midi

USB

  • robost_keyboard - demonstrate how to deal with USB disconnect for battery-powered USB HID keyboard devices
