Pico Player

MP3 player based off the looks of a walkman tape player.

Hardware:
* Pimoroni Pico
(https://shop.pimoroni.com/products/pimoroni-pico-lipo?variant=39386149093459)
* Pimoroni DAC
(https://shop.pimoroni.com/products/pico-audio-pack?variant=32369490853971)
* 2.8" Waveshare Touch Display w/ SD Card
(https://thepihut.com/products/2-8-touchscreen-display-for-raspberry-pi-pico-320x240?variant=40242871206083)
* rotary encoder i2c
(https://shop.pimoroni.com/products/adafruit-i2c-qt-rotary-encoder-with-neopixel-stemma-qt-qwiic?variant=53510839861627)
* keypad i2c
* battery

Plan is to give it an ipod-like interface, with the display fliping out like a tape player to change SD cards. I hope to get it working with FLAC files, but I may need upgraded hardware for that.

Please feel free to leave comments / suggestions! I need all the help I can get with this project!
