Justin Mitchell	61cb4946d6	Fix I2C initialization for dual X3+X4 binary Sync the runtime board profile to the detected device before I2C consumers initialize. This ensures Wire.begin() is called when needed for X3 devices. Previously, the X4 profile remained active through initialization, causing Wire to never reinitialize after detection probe, leading to X3 I2C read failures with 'could not acquire lock' errors.	2026-06-21 02:06:01 -04:00

Justin Mitchell	e42503f1a4	Preserve touch held time across gesture detection Touch held time was being lost when gestures were detected because the gesture detection happens before the touch release event. Now remembers the held time at the moment of gesture detection and returns it within a 250ms window, allowing UI elements to properly respond to long-press gestures. Also refactors deep sleep code to use PowerManager methods.	2026-06-21 01:14:40 -04:00
Justin Mitchell	c812091a4a	Make USB detection pin configurable Replace hardcoded UART0_RXD pin with configurable BoardConfig::ACTIVE.usbDetect. Also simplify wakeup reason detection logic to prioritize GPIO/EXT1 wakeup from deep sleep as PowerButton event.	2026-06-20 12:15:45 -04:00
Justin Mitchell	beb4e82c9c	Add extra bar indicator for near-complete progress Draws a small additional bar segment when progress reaches 95% or higher, positioned at x+14 within the progress bar cavity. The extra bar is capped at 3 pixels wide to fit within the available space.	2026-06-20 00:14:48 -04:00

Justin Mitchell	57c389c0b6	Add touch-down visual feedback to settings menus Handle touch-down events separately from tap events in settings activities to provide immediate visual feedback when menu items are touched, before the tap is completed. This improves UI responsiveness by updating the selected index on touch-down.	2026-06-19 14:41:21 -04:00
Justin Mitchell	06ff5aa44a	Add SDK RTC and IMU hardware abstraction support Integrate SDK-based RTC and IMU backends as alternatives to direct hardware access. HalClock now attempts SDK RTC initialization and caches time values for reliability. HalTiltSensor adds SDK IMU backend with fallback logic. ClockOffsetActivity gains touch and swipe gesture support for field navigation.	2026-06-19 14:25:51 -04:00
Justin Mitchell	526cf1b6f9	Add touch gesture support and LilyGo T5 S3 board Implements bottom-edge swipe-up gesture detection and delayed touch-select with tracking state. Adds isTouchTapCandidate() to distinguish taps from swipes. Includes LilyGo T5 S3 board configuration with USB CDC logging transport for boards where Serial operator bool reports false incorrectly.	2026-06-19 13:39:10 -04:00
Justin Mitchell	6648a980cb	Center row icons between title and subtitle When a row has a subtitle, position the icon at the midpoint between the title and subtitle text centers instead of aligning only with the title. This prevents icons from appearing too high when subtitles are present.	2026-06-17 01:41:10 -04:00

Justin Mitchell	4f55444f67	Add 2-bit compressed rendering for large UI fonts Refactor UI font generation to support different rendering modes based on size. Small UI fonts (12pt) use 1-bit rendering for crisp display and reduced flash usage. Large UI fonts (14pt) now use 2-bit compressed rendering to stay smooth when scaled up on touch/high-density boards. Extract font generation logic into reusable generate_ui_font() function.	2026-06-17 01:18:17 -04:00
Justin Mitchell	4a17d21d80	Add icon generation script and list scroll helper Introduce gen_icons.sh to regenerate UI icons from a manifest file using the FreeInk SDK's Lucide icon set. Add icons.manifest mapping UI icons to Lucide names. Refactor vertical swipe list scrolling into a reusable wasListScroll() helper method used by both reader chapter selection and settings activities. Add static assertion to ensure ThemeMetrics scaling stays in sync with struct changes.	2026-06-16 00:15:18 -04:00
Justin Mitchell	1c63847631	Cleanup pass Removed the getFontXHeight method from GfxRenderer interface.

Justin Mitchell	4a5b45409f	Add icon rendering and list scroll gesture support Implement orientation-aware icon rendering using freeink::Icon format that applies rotation transforms per-pixel. Add wasListScroll helper for touch-based list navigation with swipe gestures. Switch vertical centering from x-height to cap-height for better visual alignment with capital-led UI labels.	2026-06-15 23:37:49 -04:00
Justin Mitchell	e103cdfd11	Add UI scaling support for touch vs button devices Introduces uiScale() method to apply per-board UI scaling based on device type (1.0 for button devices, >1 for touch devices to make UI elements finger-sized). Adds scaledMetrics member to store scaled theme metrics that are returned by getMetrics().	2026-06-15 22:42:33 -04:00
Justin Mitchell	cef0d267b7	Clarify touch gesture and input API comments Simplify and clarify documentation for touch gesture detection (back gesture, item taps, long-press) and board detection flags. No functional changes, just improved comment readability.	2026-06-15 19:42:09 -04:00
Justin Mitchell	9f3dddabe6	Add touch gesture to open reader menu Implements a press-and-hold gesture in the center touch zone (400ms threshold) that opens the reader menu, mirroring the Confirm button behavior. The center third of the screen is now reserved for this menu gesture, while left and right thirds continue to handle page turns. Applied to both EPUB and XTC readers.	2026-06-15 17:16:59 -04:00
Justin Mitchell	350fc8472a	Add touch reader controls translation string Adds STR_TOUCH_READER_CONTROLS translation key across all supported languages.	2026-06-15 17:02:48 -04:00
Justin Mitchell	79ef9d6a35	Add touch reader controls for page navigation Implements tap zones on touch devices for page back/forward navigation and press-and-hold actions, mirroring physical button behavior. Adds isXteinkDevice() helper to distinguish Xteink X3/X4 boards from touch devices. The sunlight fading fix setting is now exclusive to Xteink devices, while touch devices get the new touch reader controls toggle instead.	2026-06-15 17:01:42 -04:00
Justin Mitchell	0036a220be	Split Rect constructor into default and explicit ctors Separate the default constructor from the parameterized constructor to allow value-initialization of Rect arrays without routing through an explicit constructor. The parameterized constructor remains explicit to prevent implicit int-to-Rect conversions. Member variables now use in-class initializers.	2026-06-15 16:39:32 -04:00
Justin Mitchell	8ad538c98b	Fix back gesture to use logical screen coordinates Changed the fallback corner gesture detection to use logical (orientation-mapped) coordinates instead of native panel coordinates. This ensures the gesture area remains in the visual top-left corner across all screen orientations, particularly for screens without a header or Back button target like the reader.	2026-06-15 16:28:23 -04:00
Justin Mitchell	f1b5da25b0	Expand continue-reading card clickable area Make the entire continue-reading card (cover, title, and gray area) clickable instead of just the cover photo. The clickable area now spans the full tile width rather than just the cover width plus padding.	2026-06-15 16:16:25 -04:00
Justin Mitchell	d739827db2	Add touch-down and long-press input detection Implement touch-down event detection to provide immediate visual feedback when touching list items, mirroring button navigation behavior. Add long-press detection (500ms threshold) to distinguish between tap and hold gestures. Apply touch-down selection updates to file browser, home menu, and recent books activities.	2026-06-15 16:12:07 -04:00
Justin Mitchell	9176e76f5a	Add Tab and Cover touch kinds to TouchRegistry Extends the Kind enum with two new touch interaction types: Tab (2) and Cover (3), enabling support for additional UI element touch handling.	2026-06-15 15:47:33 -04:00
Justin Mitchell	7294610894	Add touch-to-logical coordinate mapping for UI Implements tapToLogical() to convert normalized touch coordinates to orientation-aware logical screen coordinates. Adds TouchRegistry hit testing for interactive UI elements and header back button. Touch gestures now work correctly across all screen orientations (Portrait, Landscape, etc.) by inverting the rotateCoordinates transform.	2026-06-15 15:32:22 -04:00
Justin Mitchell	a51098725d	Support multi-I2C and fix ESP32-S3 USB logging Add dynamic I2C bus selection for battery gauge to support boards with multiple I2C controllers (e.g., Sticky uses Wire1 to avoid conflicts with GT911 touch). Fix logging on ESP32-S3 USB-Serial-JTAG by using esp_rom_printf instead of Serial, which incorrectly reports disconnected state.	2026-06-15 13:52:16 -04:00
Justin Mitchell	6acecd8ea6	Use board config for battery monitoring setup Replace hardcoded X3-specific I2C pins and frequencies with values from the active board profile. Add support for boards with I2C fuel gauges (X3, LilyGo, Sticky) and ADC-based battery sensing (X4, M5Paper). Skip ADC setup when batteryAdc is unassigned to prevent GPIO mux faults.	2026-06-15 12:29:24 -04:00
Justin Mitchell	9b7b9e9094	Skip X3 fingerprint probe on non-C3 boards Prevent I2C pin collision on S3/ESP32 boards by skipping the X3/X4 fingerprint probe. The probe's I2C pins (GPIO20/0) conflict with onboard peripherals like the BQ27220 gauge and reconfigure strapping pins. Force deviceType to X4 for non-C3 builds.	2026-06-15 12:26:21 -04:00

Justin Mitchell	28d8ad565f	Fix SPI bus initialization for non-C3 boards Change SPI pre-claim logic to only apply on C3/Xteink hardware where EPD_* pins are hardcoded. Other boards (M5Paper, Sticky) need to initialize SPI from BoardConfig::ACTIVE pins to avoid incorrect pin assignments for display and SD card.	2026-06-15 12:14:19 -04:00
Justin Mitchell	ed6690c0cc	Suppress cppcheck warnings for build-time switch Add cppcheck-suppress comments for knownConditionTrueFalse warnings related to CROSSPOINT_SHOW_BUTTON_HINTS, which is a build-time configuration switch that may appear as a constant condition during static analysis.	2026-06-08 14:31:55 -04:00
