M5Spot

A Spotify Web API client for M5Stack

• Display song title, artists & JPEG album art
• Play/Pause, Next, Previous with M5Stack buttons
• Easy OAuth2 authorization through browser
• SSE console in browser to look under the hood

Prerequisite

• Create an App in Spotify Developper Dashboard and declare http://m5spot.local/callback/ as the Redirect URI
• Insert a SD card in M5Stack (I don't feel comfortable using internal flash for writing JPEG files again & again)
• Rename config.h.SAMPLE to config.h and complete the settings
• Install external libraries (see platformio.ini)
• Compile and upload src
• Upload data to file system

Caveat

This is a work in progress and there is still a lot to do:

• Use 8 bits fonts with support for international characters
• Better display of title/artists (currently needs sharp eyes, and long strings are truncated)
• Better error handling
• A bit of refactoring/polishing
• Add a tap interface: Play/Pause with a tap, Next with a double tap (thanks to the gray edition with integrated MP9250)
• Eventually add a gesture interface: use hand swipes to Play/Pause/Next/Previous (via external APDS9960)
• Give option to store album art JPEG files in SPIFFS, instead of SD Card
• Cache last n JPEG files, to avoid unnecessary traffic & memory write when always playing the same songs :)
• Tests, tests, tests...

I decided to realease it anyway, just before my annual AFK period, in case someone would find it interresting enough to work on it while I'm lazying under the sun. ;)
