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
- 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 Features**
* Runtime font accessors and new symbol fonts for text, launcher, statusbar, and shared icons.
* Added font height base setting to device.properties
* Text fonts now have 3 sizes: small, default, large
**Improvements**
* Renamed `UiScale` to `UiDensity`
* Statusbar, toolbar and many UI components now compute heights and spacing from fonts/density.
* SSD1306 initialization sequence refined for more stable startup.
* Multiple image assets replaced by symbol-font rendering.
* Many layout improvements related to density, font scaling and icon scaling
* Updated folder name capitalization for newer style
* **New Features**
* Time and delay utilities added (ticks, ms, µs); SD card now uses an expansion-header CS pin; HTTP downloads warn when run on the GUI task and yield to avoid blocking.
* **Bug Fixes / Reliability**
* Many hard-crash paths converted to guarded checks to reduce abrupt termination and improve stability.
* **Tests**
* Unit tests added to validate time and delay accuracy.
* **Chores**
* License header and build/macro updates.
- `TT_LOG_*` macros are replaced by `Logger` via `#include<Tactility/Logger.h>`
- Changed default timezone to Europe/Amsterdam
- Fix for logic bug in unPhone hardware
- Fix for init/deinit in DRV2605 driver
- Other fixes
- Removed optimization that broke unPhone (disabled the moving of heap-related functions to flash)
- Added `AppHub` app
- Added `AppHubDetails` app
- Added `cJSON` dependency
- Renamed `AppSim` module to `FirmwareSim`
- Added extra `tt::app::alertdialg::start()`
- Renamed `addApp()`, `removeApp()`, `findAppById()` and `getApps()` to `addAppManifest()`, `removeAppManifest()`, `findAppManifestById()` and `getAppManifests()`
- Added `tt::lvgl::toolbar_clear_actions()`
- Added `tt::network::EspHttpClient` as a thread-safe wrapper around `esp_http_client`
- Added `tt::network::http::download()` to download files
- Added `tt::network::ntp::isSynced()`
- When time is synced, the timestamp is stored in NVS flash. On boot, it is restored. This helps SSL connections when doing a quick reset: when WiFi reconnects, the user doesn't have to wait for NTP sync before SSL works.
- Added `tt::json::Reader` as a `cJSON` wrapper
- Added `int64_t` support for `Preferences`
- Added `int64_t` support for `Bundle`
- Added dependencies: `cJSON`, `esp-tls`
- When time is synced via NTP, disable time sync.
- Added docs to 'tt::file::` functions
- Added `tt::string::join()` that works with `std::vector<const char*>`
- Fixed `tt::file::getLastPathSegment()` for the scenario when a path was passed with only a single segment
- Set `CONFIG_ESP_MAIN_TASK_STACK_SIZE=5120` (from about 3k) for all boards
- Set `CONFIG_MBEDTLS_SSL_PROTO_TLS1_3=y` for all boards
- Moved `file::getlock(path)` from `Tactility` to `TactilityCore`
- Changed all existing `file::*` functions to implement locking by default
- Removed all manual locking where `file::*` functions were used
- When `DevelopmentService` receives a file, it doesn't try to allocate it all in memory. This fixes going out-of-memory on devices without PSRAM.
- Fix for TactilityC include
## App state
Improved app state management in `LoaderService` and `GuiService`:
- Re-ordered some of the state transitions
- Hardened `GuiService` for repeated events (that might trigger a re-render of an app that's already rendered)
- Validate state transitions in `LoaderService` and crash if an app transitions from the wrong state to the next one.
## LoaderService
- Removed `tt::loader::` functions and expose `LoaderService` interface publicly.
- Implement `stopAll()` and `stopAll(id)` which stops all instances of an app, including any apps that were launched by it.
- Rename `stop()` functions to `stopTop()`
- Created `stopTop(id)` which only stops the top-most app when the app id matches.
- Moved `loader::LoaderEvent` to `loader::LoaderService::Event`
- Changed app instance `std::stack` to `std::vector`
## Improvements
- `ElfApp`: error 22 now shows a hint that `main()` might be missing
- Starting, installing and uninstalling apps now stops any running app (and its children) on the stack
## Bugfixes
- `HttpdReq` out of memory issue now shows an error message and doesn't crash anymore (this would happen on devices without PSRAM with WiFi active, when an app was installed)
- `GuiService::hideApp()` lock should not wait for timeout and now waits indefinitely
- `Buildscript/release-sdk-current.sh` deletes the previous local release before building a new one
## Code correctness
- App classes were made `final`
- Apps that had a `void start()` now have a `LaunchId start()`
- `tt::app::State`: renamed `Started` to `Created` and `Stopped` to `Destroyed` to properly reflect earlier name changes
Various improvements and new internal APIs including a new Development service+app which allows `tactility.py` to upload and run applications remotely.
- Replace C function pointers with C++ `std::function` in `Thread`, `Timer` and `DispatcherThread`
- Rename `SystemEvent`-related functions
- WiFi: fix auto-connect when WiFi disconnects from bad signal
- WiFi: fix auto-connect when WiFi fails to auto-connect
- WiFi: implement disconnect() when tapping connected WiFi ap in WiFi management app
