# circuitpython_font_play_code_simple.py -- playing w adafruit circuitpython-fonts
# 8 Aug 2025 - @todbot / Tod Kurt
# developed on a Lilygo T-Display S3 w/ ST7789 display in paralleldisplaybus mode
# To use this, first install 'circup' and do what's described here:
#   https://github.com/adafruit/circuitpython-fonts/
# e.g.: 
#  circup bundle-add adafruit/circuitpython-fonts # You only need to do this once
#  circup show | grep 48 | grep font   # find fonts that are size 48 
#  circup install font_... # find a font you like & install it, like:
#  circup install font_raleway_medium_48
