Font Build Variants

CrossInk ships multiple firmware build variants because the ESP32-C3 has limited flash and RAM. The variants trade available point sizes against emoji and miscellaneous-symbol support.

Variants

teensy

Only the smallest point sizes.

• Emoji and miscellaneous-symbol support
• 4 font sizes:
  • 8 pt
  • 9 pt
  • 10 pt
  • 12 pt

tiny

No 18 pt or 20 pt font size. This is the preferred general-purpose build.

• Emoji and miscellaneous-symbol support
• 4 font sizes:
  • 10 pt
  • 12 pt
  • 14 pt
  • 16 pt

xlarge

8 pt, 10 pt, and 12 pt font sizes are removed to reduce build size while still supporting emoji and symbols.

• Emoji and miscellaneous-symbol support
• 3 font sizes:
  • 16 pt
  • 18 pt
  • 20 pt

no_emoji

All standard font sizes from 10 pt through 18 pt are available, but emoji and miscellaneous-symbol support is removed.

• No emoji or miscellaneous-symbol support
• 5 font sizes:
  • 10 pt
  • 12 pt
  • 14 pt
  • 16 pt
  • 18 pt
