SD Card Fonts

CrossPoint supports loading additional fonts from the SD card, including fonts with extended Unicode coverage (CJK, Cyrillic, Greek, etc.).

Installing Fonts

There are three ways to install fonts:

Option 1: Download from device (recommended)

  1. Connect your CrossPoint reader to Wi-Fi
  2. Go to Settings > System > Manage Fonts
  3. Browse available font families and tap to download
  4. Downloaded fonts appear immediately in Settings > Reader > Font Family

Option 2: Upload via web browser

  1. Start File Transfer and connect through Join Network or Create Hotspot
  2. Open the web interface URL shown on the reader
  3. Navigate to the Fonts tab
  4. Upload .cpfont files using the upload form

Option 3: Manual SD card copy

  1. Download font files from the crosspoint-fonts repository

  2. Copy font family folders to one of two locations on your SD card:

    • /.fonts/ — hidden directory (preferred; keeps the SD root tidy when mounted on a desktop)
    • /fonts/ — visible directory (use this if your OS hides dot-files and you'd rather see the folder in your file manager)

    Both roots are always scanned at boot and the results are merged: a family installed in /fonts/ shows up even when /.fonts/ also exists, and vice versa. The two roots only collide if the same family name appears in both — in that case the copy in /.fonts/ wins and the duplicate in /fonts/ is ignored.

    SD Card Root/
├── .fonts/                     ← Hidden root (preferred)
│   └── Literata/
│       ├── Literata_12.cpfont
│       ├── Literata_14.cpfont
│       ├── Literata_16.cpfont
│       └── Literata_18.cpfont
└── fonts/                      ← Visible root (equally valid)
    └── Merriweather/
        ├── Merriweather_12.cpfont
        └── ...

  3. Insert the SD card and power on your CrossPoint reader

Available Pre-Built Fonts

The current list of pre-built fonts is maintained in the crosspoint-fonts repository.

Converting Custom Fonts

To convert your own TrueType/OpenType fonts:

Prerequisites

pip install freetype-py fonttools

Single font (one style)

python3 lib/EpdFont/scripts/fontconvert_sdcard.py \
  MyFont-Regular.ttf \
  --intervals latin-ext \
  --sizes 12,14,16,18 \
  --style regular \
  --name MyFont \
  --output-dir ./MyFont/

Multi-style font

python3 lib/EpdFont/scripts/fontconvert_sdcard.py \
  --regular MyFont-Regular.ttf \
  --bold MyFont-Bold.ttf \
  --italic MyFont-Italic.ttf \
  --bolditalic MyFont-BoldItalic.ttf \
  --intervals latin-ext \
  --sizes 12,14,16,18 \
  --name MyFont \
  --output-dir ./MyFont/

Combine presets with commas: --intervals latin-ext,greek,cyrillic

You can also specify arbitrary Unicode ranges directly: --intervals latin-ext,(0x2100-0x214F)

To list all presets with codepoint counts:

python3 lib/EpdFont/scripts/fontconvert_sdcard.py --list-presets

Additional options

--force-autohint — force FreeType's auto-hinter instead of the font's native hinting (useful when a font's built-in hints produce poor results at small sizes).

Install custom fonts via the web interface or manual SD card copy.
