Replace LGPL from past commit with Apache License 2.0 for the newly created projects:
- in Platforms/*
- TactilityKernel
Add license headers to source code in:
- in Platforms/*
- TactilityKernel
- TactilityFreeRtos
Updated LICENSE.md
**New features**
- Created a devicetree DTS and YAML parser in Python
- Created new modules:
- TactilityKernel (LGPL v3.0 license)
- Platforms/PlatformEsp32 (LGPL v3.0 license)
- Platforms/PlatformPosix (LGPL v3.0 license)
- Tests/TactilityKernelTests
Most boards have a placeholder DTS file, while T-Lora Pager has a few devices attached.
**Licenses**
Clarified licenses and copyrights better.
- Add explanation about the intent behind them.
- Added explanation about licenses for past and future subprojects
- Added more details explanations with regards to the logo usage
- Copied licenses to subprojects to make it more explicit
- WiFi code cleanup
- When WifiConnect opens and SSID is filled in, automatically focus on the password field
- When no touch screen is present, toolbar close buttons should be automatically selected
- When `device.py` selects a device, print it on screen
To avoid keeping track of a list that maps board project names to board ids.
Because of this change, we don't have to manually edit `boards.cmake` anymore when adding a new board.
- Refactor `Ili934xDisplay` to use `EspLcdSpiDisplay` as base class
- Update `St7789Display` for changes to `EspLcdDisplayV2` related to ILI934x driver
- Updated all board driver implementations for ILI934x driver changes
- Simplified board configurations:
- All boards now have a `Configuration.cpp`
- All board config's headers are removed
- Removed `Boards.h`
- Fix for untar-ing large files
- Increase main task stack size to avoid stackoverflow when downloading apps in App Hub
- Reduce SPI frequency for ST7789 displays (according to spec)
## Improvements
- Created new base driver classes: `EspLcdDisplayV2' and `EspLcdSpiDisplay`
- Updated `St7789Display` to implement `EspLcdSpiDisplay`
- Updated all boards with ST7789 display
## Fixes
- Ensure that `tmp/` is created on startup (for all writeable filesystems)
- Fix for `lv_list` padding on small screen devices
- Fix for `PreferencesEsp` not processing result when writing string to NVS
## Other
- Remove unused build scripts
- 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
## 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
- Refactor `AppManifest`: add new fields and rename existing ones
- Parse and validate the manifest from an app that is being installed.
- Remove deprecated `scoped()` from `Lock`
- Create `Tactility/Paths.h`
- App loading at boot now properly parses the manifest files of external apps
- Properly lock both source and destination locations during app install
- Remove LVGL path variants from `AppPaths` and `ServicePaths`
- Removed `xPath` base classes for apps and services. There's now `AppPaths` and `ServicePaths`.
- Renamed app and service paths: "data" and "system" paths are now "user data" and "assets"
- Update ILI9341 driver to v2.0.1
- Lots of code cleanup for apps
- Refactor app "type" into "category" and added flags to the manifest (for show/hide statusbar and for hidden apps)
- Rename some ElfApp-related functionality and improved the way the static data was managed
- Rename "filebrowser" to "files"
- Added cstring functions to tt_init.cpp
- Minor fix in Boot app
- Updated external apps for SDK changes
### Cardputer:
- Fix keyboard issue with up/down button conflict when selecting switch
- Fix backlight flickering
### UI improvements
- Removed a 3 pixel border that went around the entire desktop environment
- Improved system layout (GuiService)
- Statusbar: improved layout (mainly margin/padding)
- Toolbar: fixed margin/padding of all buttons, fixed alignment of all content
- Improved layout/UI of many apps
### Other
- Update LVGL to 9.3.0 official release (was dev version)
- Implement `UiScale` in `hal::Configuration`: small screens with no touch can now opt for a more optimized experience (e.g. Cardputer, Waveshare 1.47, Waveshare 1.3", etc.)
- Fix for Cardputer UART configuration and added I2C configuration
- Fix for software keyboard bug in Gui
- Removed deprecated fields from `hal::Configuration`
- Updated the simulator devices to use the new HAL config
- add `bool tt::hal::hasDevice(Device::Type)`
- Cleanup of `AppList` app code
- Improve `Gpio` app for small screen devices
- Added various ESP32 GCC wrappers to wrap LVGL functions (with manipulations for small screen devices)
- Moved `Launcher` assets to `assets/` subfolder
- Optimized `Toolbar` for small screen devices
- Stop showing `system/` partition in `FileBrowser` because it's read-only and not very useful. Created `config::SHOW_SYSTEM_PARTITION` to override this behaviour.
- Hide apps when their required hardware isn't available (I2C, UART, PowerDevice)
- Fix for `CYD-2432S032C` DPI setting
- `FileBrowser` app now supports deleting directories (recursively)
- `DevelopmentService` and `tactility.py` now support the app `uninstall` action
- Fix crash for `File` app: implement file locking in several places (SPI SD cards need it)
- Remove I2C configuration from `M5stackCardputer.cpp` because we don't support the "Cardputer Adv" variant in that firmware.
## New features
- Implemented support for app packaging in firmware and `tactility.py`: load `.app` files instead of `.elf` files. Install apps remotely or via `FileBrowser`.
- Ensure headless mode works: all services that require LVGL can deal with the absence of a display
- Service `onStart()` is now allowed to fail (return `bool` result)
- Added and improved various file-related helper functions
## Improvements
- Completely revamped the SystemInfo app UI
- Improved Calculator UI of internal and external variant
- Fix Chat UI and removed the emoji buttons for now
- Fix for toolbar bottom padding issue in all apps
## Fixes
- Fix for allowing recursive locking for certain SPI SD cards
