The system allows users to load custom TrueType/OpenType fonts (converted to a binary format) from an SD card and select them via the settings UI. + +## System Overview + +The custom font system consists of four main components: +1. **Font Converter (`fontconvert.py`)**: A Python script that pre-processes standard fonts into a custom optimized binary format (`.epdfont`). +2. **Font Manager (`FontManager`)**: Scans the SD card for valid font files and manages loaded font families. +3. **Font Loader (`CustomEpdFont`)**: Handles the low-level reading of the binary format, including on-demand caching of glyph bitmaps to save RAM. +4. **UI & Integration**: A settings activity to select fonts and integration into the main rendering loop. + +## 1. Font Conversion & Format + +To optimize for the limited RAM of the ESP32 and the specific requirements of E-Ink displays, fonts are not loaded directly as TTF/OTF files. Instead, they are pre-processed. + +* **Script**: `lib/EpdFont/scripts/fontconvert.py` +* **Input**: TTF/OTF files. +* **Output**: `.epdfont` binary file. +* **Format Details**: + * **Header**: Contains metadata (magic "EPDF", version, metrics, offsets). + * **Intervals**: Unicode ranges supported by the font. + * **Glyphs**: Metrics for each character (width, height, advance, offsets). + * **Bitmaps**: 1-bit or 2-bit (antialiased) pixel data for glyphs. + +## 2. Storage & Discovery + +Fonts are stored on the SD card in the `/fonts` directory. + +* **Location**: `/fonts` +* **Naming Convention**: `Family-Style-Size.epdfont` + * Example: `Literata-Regular-14.epdfont` + * Example: `Literata-BoldItalic-14.epdfont` +* **Manager**: `src/managers/FontManager.cpp` + * **Scans** the `/fonts` directory on startup/demand. + * **Groups** files into `Family -> Size -> Styles (Regular, Bold, Italic, BoldItalic)`. + * Exposes available families to the UI. + +## 3. Low-Level Implementation (RAM Optimization) + +The core logic resides in `lib/EpdFont/CustomEpdFont.cpp`. + +* **Inheritance**: `CustomEpdFont` inherits from `EpdFont`. +* **Metadata in RAM**: When a font is loaded, only the *header* and *glyph metrics* (width, height, etc.) are loaded into RAM. +* **Bitmaps on Disk**: Pixel data remains on the SD card. +* **LRU Cache**: A small Least Recently Used (LRU) cache (`MAX_CACHE_SIZE = 30`) holds frequently used glyph bitmaps in RAM. + * **Hit**: Returns cached bitmap. + * **Miss**: Reads the bitmap from the SD card at the specific offset, caches it, and returns it. +* **Benefit**: Allows using large fonts with extensive character sets (e.g., CJK) without exhausting the ESP32's heap. + +## 4. User Interface & Selection + +The user selects a font through a dedicated Settings activity. + +* **File**: `src/activities/settings/CustomFontSelectionActivity.cpp` +* **Flow**: + 1. Lists available font families retrieved from `FontManager`. + 2. User selects a family. + 3. Selection is saved to `SETTINGS.customFontFamilyName`. + +## 5. Main Integration + +The selected font is applied during the system startup or when settings change. + +* **File**: `src/main.cpp` +* **Function**: `setupDisplayAndFonts()` +* **Logic**: + 1. Checks if `SETTINGS.fontFamily` is set to `FONT_CUSTOM`. + 2. Calls `FontManager::getInstance().getCustomFontFamily(...)` with the saved name and current font size. + 3. If found, the font is dynamically inserted into the global `renderer` with a generated ID. + 4. The renderer then uses this font for standard text rendering. + +## Code Path Summary + +1. **SD Card**: `SD:/fonts/MyFont-Regular-14.epdfont` +2. **Wait**: `FontManager::scanFonts()` finds the file. +3. **Select**: User picks "MyFont" in `CustomFontSelectionActivity`. +4. **Load**: `main.cpp` calls `renderer.insertFont(..., FontManager.getCustomFontFamily("MyFont", 14))` +5. **Render**: `CustomEpdFont::getGlyphBitmap()` fetches pixels from SD -> Cache -> Screen. diff --git a/SettingsActivity_HEAD.cpp b/SettingsActivity_HEAD.cpp new file mode 100644 index 00000000..efa0b9e1 --- /dev/null +++ b/SettingsActivity_HEAD.cpp @@ -0,0 +1,224 @@ +#include "SettingsActivity.h" + +#include +#include + +#include + +#include "CalibreSettingsActivity.h" +#include "CrossPointSettings.h" +#include "MappedInputManager.h" +#include "OtaUpdateActivity.h" +#include "fontIds.h" + +// Define the static settings list +namespace { +constexpr int settingsCount = 20; +const SettingInfo settingsList[settingsCount] = { + // Should match with SLEEP_SCREEN_MODE + SettingInfo::Enum("Sleep Screen", &CrossPointSettings::sleepScreen, {"Dark", "Light", "Custom", "Cover", "None"}), + SettingInfo::Enum("Sleep Screen Cover Mode", &CrossPointSettings::sleepScreenCoverMode, {"Fit", "Crop"}), + SettingInfo::Enum("Status Bar", &CrossPointSettings::statusBar, {"None", "No Progress", "Full"}), + SettingInfo::Enum("Hide Battery %", &CrossPointSettings::hideBatteryPercentage, {"Never", "In Reader", "Always"}), + SettingInfo::Toggle("Extra Paragraph Spacing", &CrossPointSettings::extraParagraphSpacing), + SettingInfo::Toggle("Text Anti-Aliasing", &CrossPointSettings::textAntiAliasing), + SettingInfo::Enum("Short Power Button Click", &CrossPointSettings::shortPwrBtn, {"Ignore", "Sleep", "Page Turn"}), + SettingInfo::Enum("Reading Orientation", &CrossPointSettings::orientation, + {"Portrait", "Landscape CW", "Inverted", "Landscape CCW"}), + SettingInfo::Enum("Front Button Layout", &CrossPointSettings::frontButtonLayout, + {"Bck, Cnfrm, Lft, Rght", "Lft, Rght, Bck, Cnfrm", "Lft, Bck, Cnfrm, Rght"}), + SettingInfo::Enum("Side Button Layout (reader)", &CrossPointSettings::sideButtonLayout, + {"Prev, Next", "Next, Prev"}), + SettingInfo::Toggle("Long-press Chapter Skip", &CrossPointSettings::longPressChapterSkip), + SettingInfo::Enum("Reader Font Family", &CrossPointSettings::fontFamily, + {"Bookerly", "Noto Sans", "Open Dyslexic"}), + SettingInfo::Enum("Reader Font Size", &CrossPointSettings::fontSize, {"Small", "Medium", "Large", "X Large"}), + SettingInfo::Enum("Reader Line Spacing", &CrossPointSettings::lineSpacing, {"Tight", "Normal", "Wide"}), + SettingInfo::Value("Reader Screen Margin", &CrossPointSettings::screenMargin, {5, 40, 5}), + SettingInfo::Enum("Reader Paragraph Alignment", &CrossPointSettings::paragraphAlignment, + {"Justify", "Left", "Center", "Right"}), + SettingInfo::Enum("Time to Sleep", &CrossPointSettings::sleepTimeout, + {"1 min", "5 min", "10 min", "15 min", "30 min"}), + SettingInfo::Enum("Refresh Frequency", &CrossPointSettings::refreshFrequency, + {"1 page", "5 pages", "10 pages", "15 pages", "30 pages"}), + SettingInfo::Action("Calibre Settings"), + SettingInfo::Action("Check for updates")}; +} // namespace + +void SettingsActivity::taskTrampoline(void* param) { + auto* self = static_cast(param); + self->displayTaskLoop(); +} + +void SettingsActivity::onEnter() { + Activity::onEnter(); + renderingMutex = xSemaphoreCreateMutex(); + + // Reset selection to first item + selectedSettingIndex = 0; + + // Trigger first update + updateRequired = true; + + xTaskCreate(&SettingsActivity::taskTrampoline, "SettingsActivityTask", + 4096, // Stack size + this, // Parameters + 1, // Priority + &displayTaskHandle // Task handle + ); +} + +void SettingsActivity::onExit() { + ActivityWithSubactivity::onExit(); + + // Wait until not rendering to delete task to avoid killing mid-instruction to EPD + xSemaphoreTake(renderingMutex, portMAX_DELAY); + if (displayTaskHandle) { + vTaskDelete(displayTaskHandle); + displayTaskHandle = nullptr; + } + vSemaphoreDelete(renderingMutex); + renderingMutex = nullptr; +} + +void SettingsActivity::loop() { + if (subActivity) { + subActivity->loop(); + return; + } + + // Handle actions with early return + if (mappedInput.wasPressed(MappedInputManager::Button::Confirm)) { + toggleCurrentSetting(); + updateRequired = true; + return; + } + + if (mappedInput.wasPressed(MappedInputManager::Button::Back)) { + SETTINGS.saveToFile(); + onGoHome(); + return; + } + + // Handle navigation + if (mappedInput.wasPressed(MappedInputManager::Button::Up) || + mappedInput.wasPressed(MappedInputManager::Button::Left)) { + // Move selection up (with wrap-around) + selectedSettingIndex = (selectedSettingIndex > 0) ?

Application State & Settings + +* **`src/CrossPointSettings.{cpp,h}`**: + * Added persistent storage for the selected `customFontFamily`. + * Updated `getReaderFontId()` to resolve IDs dynamically via `EpdFontLoader` when a custom font is selected. +* **`src/main.cpp`**: + * **CRITICAL FIX**: Re-enabled `verifyWakeupLongPress()` to prevent the device from accidentally powering on when plugged in or bumped. + * Integrated `EpdFontLoader::loadFontsFromSd` into the startup sequence. + +## 5.
