lvgl-module/symbols.c:
- canvas: full LVGL9 docs API (get_buf, get_image, get_px, get_draw_buf,
set_palette, copy_buf, init_layer, finish_layer, buf_size) – was only 5 symbols
- draw_buf: create/destroy/init/dup/copy/goto/clear/width_to_stride/align/palette/from_image/to_image
- cache: lv_draw_buf_invalidate_cache, flush_cache, lv_image_cache_drop – critical bugfix for
GameBoy (and any direct framebuffer) where raw buf mutated but image cache stale -> FPS but no image.
- draw layer helpers, image scale/rotation/pivot/offset, transform scales for GB 2x/3x integer scaling
Reason blank screen: lv_canvas in LVGL9 is lv_image backed by draw_buf. Mutating raw pointer
without lv_image_cache_drop + invalidate_cache leaves stale texture. Timer was calling
lv_obj_invalidate only. Now exports needed symbols and app fixed to drop cache each frame.
mDNS (preserve from local WIP, sits on top of 60764979 'kidsOS-XXXX' mdns init):
- Tactility/network/Mdns.h/cpp: C++ browse + resolveHostname wrappers around esp-idf mdns 1.3.2
(PTR query, txt records, address extraction, POSIX stub)
- TactilityC/tt_mdns.h/cpp: C copy-based API for ELF apps (TT_MDNS_MAX_RESULTS 32,
capped addresses/txt, hostname->IP resolve)
- TactilityC/tt_init.cpp: export tt_mdns_is_available / browse / resolve_hostname symbols
Test plan:
- firmware build for es3c28p --dev
- release-sdk-current.py
- GameBoy app build against new SDK (0 missing symbols expected)
- push both branches to personal gitea
- Auto-set enableOnBoot=true when BT is enabled or device is paired,
so board restarts with BT on and can reconnect
- Make RADIO_STATE_ON handler non-exclusive: scan for HID Host,
start HID Device, SPP and MIDI all independently (was else-if)
- Improve HID Host auto-connect for RPA: direct addr match, name-match
fallback, and direct connect to stored identity using resolving list
- Persist addrType in PairedDevice file for more reliable reconnection
- Add verbose logging for loadAll/save to debug missing files
Fixes issue where board restart did not reconnect to previously
connected BT devices. Also preserves f94cc160 fullscreen flag feature.
- Add parseAppFlagsString() in AppManifestParsing.cpp to parse comma-separated flags (HideStatusBar, Hidden, None)
- Parse [app]flags in V1 and app.flags in V2 manifests
- Loader already supports HideStatusBar, GuiService hides statusbarWidget when set
- Enables fullscreen for ELF apps (e.g. BibleVerse, BookPlayer) without firmware recompilation of internal manifests
- Add tests for flag parsing (38 tests passing)
- Tested on es3c28p /dev/cu.usbmodem1101 @ 192.168.68.133 with HelloWorld app
- es8311 driver open() now allows OUTPUT->INPUT complementary (promotes to BOTH) when same native rate 44100
- audio-stream close_stream() ref-counts shared BOTH codec (don't close if other direction still open)
- MCP recordVoice + VoiceRecorder app explicitly unmute and set 100% gain
Fixes mic input not working - was returning ERROR_RESOURCE when output already open
- SupportedFiles: add isSupportedAudioFile (.mp3/.wav/.ogg/.flac)
- Files View::viewFile: if audio file, loader->start one.tactility.mp3player with file bundle
- Tactility.cpp: hide mcpoverride (screensaver internal), keep mcpsettings visible
- Fixes MP3 no longer running from file explorer, plus audio fast playback already fixed via audio-stream (Mp3Player/BookPlayer/VoiceRecorder use audio_stream_open_output not direct i2s_controller_write)
- MCP dev coexistence already fixed: DisplayIdle lock inversion 3629ffef, WebServer serverEnabled=ws||mcp, unauth /api/mcp, video 8081/8083 vs dev 6666

- flashed to /dev/cu.usbmodem101 2884320 -> 1672312 hash verified
- LVGL image cache 512KB + header cache 16 on PSRAM (was PNG bottleneck, c4ec7ead)
- DisplaySettings.disableScreensaverWhenCharging persisted, checked via PowerDevice::IsCharging
- Display app: 'Disable on charging' toggle under Display settings, auto-disabled when timeout off
- DisplayIdle: skip screensaver while charging, auto-stop if plugging in while dimmed
- Keeps upstream full-DTS board clean, no JPEG decoder, no BT HID combo per user
- RGB display driver added
- display_driver API:
- Added software-based display rotation for screens without hardware rotation support.

- Updated flash scripts
- Fix for esp32 legacy driver conflict with ADC
- Created separate `lilygo-tdeck` and `lilygo-tdeck-plus` devices
- Created `lilygo-module` with LilyGO kernel drivers
- Fix for intermittent errors in build related to code generation of `devicetree.c`
- `lvgl-module` can now map kernel drivers onto LVGL devices
- Created `KernelDisplayApp` as a mirror of `HalDisplayApp` (formerly `DisplayApp`)
- Removed `struct` and `enum` prefix in a lot of kernel driver cpp source files
- `lilygo-tdeck` and `lilygo-tdeck-plus` are now fully relying on kernel drivers and don't use any of the old HAL
* Tab5 camera + other stuff
Tab5 camera driver - SC2356
Custom SliderBox widget - slider with plus and minus buttons + value label and snapping
Rtc Time service + rtc api
Sdk release - only include drivers built for that specific target, eg: sc2356 driver is mipi / p4 only.
No more hardcoded manual sdk cmakelists
New function to find device by compatible string match. no more static cast bool wildness when trying to match a single device (like M5Stack PaperS3 for example)
* feedback + fixes
Fixed external app user data path.
fix(gui): block app teardown until onHide() completes, preventing ELF unload racing a still-running app
added camera device type and api
* drain the snake sssem

- Fixed crash when returning to Setup app (from any of the steps)
- Fixed crash when returning to TimeDateSettings app (after locale selection)
- Fixed GuiService inconsistent behaviour: now always perform operations async (e.g. to show/hide apps). This fixes crashes in some onHide() calls where onHide() might be called before onShow() was called.
- Fix for incorrect WebServService path
- Remove CYD-4848S040C SD card functionality, but added a GPIO fix for releasing 3-wire SPI pin sharing.
- Fix for saving/loading settings for various apps
- Implement Setup app for device's first boot
- Implement device simple name and vendor name variables
- Remove region setting (locale setting is already available)
- Disable BlueTooth driver by default, to ensure it doesn't allocate memory
- Update BlueTooth settings app behaviour to make sure it starts/stops the devices
- Disable SPI RAM usage for ST7789 as it broke App Hub
- Reduce T-Display and T-Deck display buffers from 1/3rd to 1/10th of resolution
- Enabled dynamic buffers for MbedTLS to optimize memory
- TLS 1.3 did not work with dynamic buffers: downgrade to 1.2 for now
- WiFi is now enabled from the Boot app callback to the WiFi service, instead of the WiFi service start() function. This avoids a lockup when WiFi is started by the service while the Boot app is updating the WiFi settings.
- New drivers:
- SD SPI
- spi_peripheral
- touch_placeholder
- display_placeholder
- Devicetree compiler:
- Implement phandle-arrays
- Implement device addresses
- Add placeholder drivers to all devices with a SPI display
- SPI driver: add `cs-pins` and set them to high on driver start
- FileSystem: add `file_system_set_owner()` and `file_system_get_owner()`
- File locking is now checking if the related `FileSystem` is part of a shared SPI bus
- Add `device_get_child_count()`
- SDMMC driver: Remove default of `slot` value
- Fix for Crowpanel Basic 3.5" display (add delay to booting)
- Fix for LilyGO T-HMI SD card mounting (delayed mounting by disabling it initially in the dts)
