- created `tt_lvgl_*`
- export `tt_app_*` calls
- Refactored `TouchDevice`: it can now start/stop LVGL separately, and it has an optional `TouchDriver` interface
- Refactored `DisplayDevice`: it can now start/stop LVGL separately, and it has an optional `DisplayDriver` interface
- Updated all boards and drivers for above changes
- LVGL can now be stopped and (re)started on the fly
- Fixed issues with restarting Gui and Statusbar services

- LVGL performance improvements: pin to second core and set task priority to "critical"
- Fix build warnings, including deprecations
- Removed deprecated `Thread` constructor

- Files app now uses proper SD card mount point name (and multiple SD cards)
- Removed `TT_SCREENSHOT_MODE`
- Added `tt::hal::Device` and functions (de)register devices and search for them.
- Refactored apps: `Power` and `Display` settings apps now use the device API to find devices.
- Implemented the new API for all existing drivers for all devices, including the simulator.
- Updated HAL Configuration to return `std::shared_ptr` instead of raw pointers.
- Added test project for headless tests and implemented tests for the new code.
- Create `Include/` folder for all main projects
- Fix some issues here and there (found while moving things)
- All includes are now in `Tactility/` subfolder and must be included with that prefix. This fixes issues with clashing POSIX headers (e.g. `<semaphore.h>` versus Tactility's `Semaphore.h`)
- Lots of changes for migrating C code to C++
- Improved `Lockable` in several ways like adding `withLock()` (+ tests)
- Improved `Semaphore` a bit for improved readability, and also added some tests
- Upgrade Linux machine in GitHub Actions so that we can compile with a newer GCC
- Simplification of WiFi connection
- Updated funding options
- (and more)
FreeRTOS handles were stored plainly and they were deleted in the destructor of classes.
This meant that if a class were to be copied, the destructor would be called twice on the same handles and lead to double-free.
Seha on Discord suggested to fix this by using `std::unique_ptr` with a custom deletion function.
The changes affect:
- Thread
- Semaphore
- Mutex
- StreamBuffer
- Timer
- MessageQueue
- EventFlag
Thread changes:
- Removal of the hack with the `Data` struct
- Thread's main body is now just a private static function inside the class.
- The C functions were relocated to static class members
PubSub changes:
- Refactored pubsub into class
- Renamed files to `PubSub` instead of `Pubsub`
- `PubSubSubscription` is now a private inner struct and `PubSub` only exposes `SubscriptionHandle`
Lockable, ScopedLockable, Mutex:
- Added `lock()` method that locks indefinitely
- Remove deprecated `acquire()` and `release()` methods
- Removed `TtWaitForever` in favour of `portMAX_DELAY`
- unPhone improvements related to power and boot (add boot count logging)
- Cleanup of Mutex acquire/release
- Removed `tt_assert()` in favour of `assert()`
- Fix sim build (likely failed due to migration of GitHub Actions to Ubuntu 24.04)
- Fix for unPhone sleep: it would wake up every minute briefly (draining the battery over the course of 1-3 days)
- Minor WiFi improvements (mainly added logging and improved filtering on connect .. the latter probably doesn't matter)
- Remove custom `ESP_TARGET` and use `ESP_PLATFORM` everywhere
- Add `Loader` service functionality to `tt::app::` namespace
- Make `Loader` `PubSub` usable by exposing the messages
- Add board type to crash log
- Don't show SD card in Files app when it's not mounted
- Set default SPI frequency for SD cards
- Move TT_VERSION to scope that works for sim too
- Log Tactility version and board on boot
- Rename "Yellow Board" to "CYD 2432S024C"
- Refactor the way apps work: Instead of a C interface, they are now C++ classes. The main reasoning is that attaching data to an app was cumbersome. Having different implementations for different kinds of apps was cumbersome too. (3 or 4 layers of manifest nesting for the TactilityC project)
- External apps are still written in C, but they get a createData/destroyData in their manifest, so:
- External apps now have their own manifest.
- All functions in the original AppManifest are removed and replaced by a single `createApp` function
- External apps now automatically register (each app individually!) when they run the first time. As a side-effect they become visible in the `AppList` app!
- Adapted all apps for the new interface.
- Adapted all internal logic for these changes (Gui, ViewPort, Loader, AppContext, AppInstance, etc.)
- Rewrote parts of Loader to use std::shared_ptr to make the code much safer.
- Added a refcount check for the `AppInstance` and `App` at the end of their lifecycle. Show warning if refcount is too high.
- Debounce nav button presses: This fixes multiple triggers on a single press to navigate back. Otherwise, more than 1 app would often close at the same time.
- Nav button respond to release instead of push down, because these buttons aren't super reliable in general. (I might change this in the future after more testing)
- Move single buzz earlier in boot phase, so that we can detect silent boot loops.
- Implemented [unPhone](https://unphone.net/) v9 board
- Updated `.clang-format` to better reflect the intended code style
- Fix SD card compatibility issues for all boards (frequency wasn't set well)
- Moved `I2cDevice` class from CoreS3 board project to TactilityHeadless project
- Tactility configuration now has default empty lists for apps and services fields
- Fix for Launcher app: we don't need padding when showing it vertically
- Fix for I2cDevice read/write calls that checked for `esp_err_t` instead of `bool`
- Fix for TinyUSB init that checked for `esp_err_t` instead of `bool`
- Various improvements to Thread and Timer:
- Remove "mark as static" option as it is unused
- Implemented core pinning for ESP32 platforms
- Use `TickType_t` consistently (instead of `uint32_t`)
- Use `enum class` instead of `enum`
- Fix for `flash.sh` not working when using `pip` to install `esptool`
## Time & Date
- Added time to statusbar widget
- Added Time & Date Settings app
- Added TimeZone app for selecting TimeZone
- Added `tt::time` namespace with timezone code
## Other changes
- Added `SystemEvent` to publish/subscribe to system wide (e.g. for init code, but also for time settings changes)
- Changed the way the statusbar widget works: now there's only 1 that gets shown/hidden, instead of 1 instance per app instance.
- Moved `lowercase()` function to new namespace: `tt::string`
- Increased T-Deck flash & PSRAM SPI frequencies to 120 MHz (from 80 MHz)
- Temporary work-around (+ TODO item) for LVGL stack size (issue with WiFi app)
- Suppress T-Deck keystroke debugging to debug level (privacy issue)
- Improved SDL dependency wiring in various `CMakeLists.txt`

- Rename `Desktop` app to `Launcher`
- Fix for hard-coded app start of `Launcher` and `CrashDiagnostics` apps.
- Ensure `Launcher` icons are clickable, even if they're not loading.
- Don't show error scenario for SD card in statusbar when SD card status is unknown (this happens during Mutex timeout due to LVGL rendering delays)
- Cleanup deprecated `Mutex` methods.
- `hal::getConfiguration()` now returns a pointer instead of a reference, just like `tt:getConfiguration()`
- Rename `assets` and `config` partitions to `system` and `data`
- Change partition type from `spiffs` to `fat`, so we can have sub-directories
- Fix crash when doing WiFi scan: Increased system event task size to 3kB.
- Free up IRAM on ESP32 (it was required for the Core2, but I also freed up the same amount for Yellow Board)
- Introduced `Paths` objects that can be retrieved by `AppContext` and `ServiceContext`. Apps and services now have their own relative paths. Assets were re-arranged into the correct paths.
- Rename simulator window title to "Tactility"
- Refactored statusbar widget so it persists icon paths properly (it kept a const char* reference, but didn't copy it, so it crashed when the related std::string was destroyed)
- Created `Partitions.h` to expose some useful variables
- Moved USB config in various `sdkconfig` (it was part of the "default" section, but it shouldn't be)
- Updated domain name
I2C:
- Lock timeout set to reasonable times
- Check lock status in all functions
- Refactor lock/unlock to return `bool` values
- Implement functions in TactilityC
