I am using an Adafruit Trinket M0 to program a small game and would like to save the game state every so often. I am programming it through the Arduino IDE as the chip does not have enough space to run my game with circuitpython (too many libraries). Does the Trinket M0 have any form of persistent storage that I can use, or will I need to use a different device?
I couldn't find EEPROM in the documentation, but I wasn't able to find a definitive answer whether or not it has any form of long term storage. Knowing the board is based on the Attiny85 I would expect it to have 512 bytes or so, but the arduino library is giving me problems when I try to use it as well, so there is no way for me to trial and error this.
