- External apps can opt into automatic cleanup when they exit, including tracked tasks, threads, files, directories, and memory.
- App-relative file paths resolve against the app’s working directory, with `.` and `..` normalized.
- The shell identifies ELF binaries that cannot be executed instead of treating them as scripts.
- Shared icon fonts now offer distinct default and large sizes, with updated icons across the interface.
- ESP32 apps can load additional ELF formats when address mirroring is enabled.
- Terminal colors render clearly on monochrome displays, and toolbar buttons have cleaner styling.
- GPS settings safely refresh their device list when their window is hidden or its widgets are destroyed.
New features:
- SDK version 7.0.0 packages include version metadata and platform-specific application settings.
- Apps gain POSIX support for file polling, terminal attributes, and standard input/output, plus additional C and POSIX functions.
- Shell commands can launch installed headless apps using their registered app settings.
- Apps can exit with a status code, and terminal clear commands support clearing from the cursor to the end, from the start through the cursor, or the entire display.
Fixes:
- SDK integration builds locate the build tool reliably and use settings for the selected platform.
- ESP32 file operations handle invalid paths and existing directories more consistently.
- Refactored shell parsing so that the callstack doesn't increase when script complexity increases.
- Improved terminal input handling: input delay from +- 100 ms to at most about 16 ms.
DTS modules (device modules) often have a single source file with an empty `struct Module`.
The module's yaml file now allows a `dts-only` boolean to be set, so the source file becomes optional.
`devicetree.yaml` is renamed everywhere to `module.yaml`
app-module
- Apps now have support for:
- environment variables (inherit from parent app)
- current workdir
- window size (when running in terminal)
- Add type aliases like `AppId` and `PackageId`
- Remove data duplication between ledger and app instance records: create `AppManifestSet`
- `AppManifest` usage safety improved: pass by value where needed, or use `AppId` instead of a manifest.
Terminal and shell
- Moved shell commands into coreutils-module as proper apps.
- Refine stack size for terminal and shell because apps now run with their own task and stack (including in-memory apps)
Platform
- Fix for listing root dir on ESP32: wrap posix directory functions and wire in file systems.
- Moved all platform-specific file system init code to platform subprojects
Other
- Fix for screenshot capture (issue with paths)
- Fixes for coreutils app correctness
- Memory optimizations (use more PSRAM where possible) in various locations such as app-module, shell and terminal.
- `ls` and `help` commands now use terminal width and show columns of data by default
- Created fs helpers at `TactilityKernel/include/tactility/filesystem/fs.h` (partially ported from `ShellFs`)
app-module:
- Implement `AppStartContext` to reduce amount of `app_start_` and `app_exec` functions: replace them with `app_start_with_context()`
- Add support for environment variables when starting apps
- Implement support for environment variables for apps
graphics-module:
- Add this new module
- Move font-module code into this module
- Implement pixel_buffer
apps:
- Terminal app: reduce memory usage by only buffering a single row of characters, and try to buffer in IRAM when possible. Implement new pixel_buffer.
- App List: Mark apps as favourite to pin them on top. Use touch or press "x" key.
- App List: Add toolbar button that shows alert dialog with info about using favourites
Features:
- Implemented terminal app based on BreezyBox
- Implemented shell based on BreezyBox
- Added font-module with fixed-width fonts
Improvements:
- Improved application standard-output and error-output routing, including dynamically loaded applications.
- Updated shared icons and Material Symbols mappings.
- Other improvements & fixes
- Run SDL from main() and place FreeRTOS in separate thread. This fixes macOS support.
- Updated GitHub Actions to publish macOS simulator build for testing, updated amd64 to x86_64 for consistent naming.
- CL-32 features added:
- Hardware revision detection
- v0.3 and v0.4 keyboard
- v0.4 power supply
- Inlined epd library (was a module) and made changes to the device definition (don't do full update after 5 small updates)
- Statusbar: add support for inverted colors
- e-paper driver improvements and warning fixes
- Implemented gpio_controller_get_level()
- Keyboard support improvements (unicode for tca drivers)
- Apps can be launched directly from file paths (including Files app support)
- Added executable detection to identify unsupported or invalid binaries before launch.
- App startup is now streamlined through separate registered-app and direct-execution interfaces.
- Existing app launch points were migrated to the updated startup APIs.
- Added POSIX desktop support for SDK builds, application packaging, and integration testing.
- Added POSIX filesystem partitions and improved application path handling.
- Added simulator support for loading and running applications dynamically.
- Improved simulator task stack handling and display startup reliability.
- Improved simulator display scaling, resizing, high-DPI support, and pointer accuracy.
- Fixed LVGL timers and input polling on POSIX. (fixes simulator with Linux on some Intel graphics platforms)
- Standardized data paths across platforms.
- Logging now works via separate task: this allows apps to write to log without it affecting their stdout (for apps that output text as relevant date for other apps, like the File Selection app)
- Fixes for app stdio
Implement file IO for applications to facilitate text input/output capturing.
Apps can now launch apps and:
- Read their stdio output
- Write to their stdio input
- Removed TactilityC, moved its symbols to existing modules and several new ones (pthread-module, c-symbols-module, cpp-symbols-module, posix-symbols-module, freertos-module).
- Removed Firmware subproject and moved main() into Tactility subproject.
- Strengthened application archive, path, version, stack-size, and device validation.
- Moved symbol resolution for elf_loader to app-esp32-module.
- Improved `struct Module` declarations and made module and symbol definitions in modules more consistent.
- Removed old http download code from Tactility subproject.
- Rename app-module's source files for consistency.
- Add missing pthread symbols.
- Kernel module symbols are now resolvable on all platforms.
- Apps can specify task stack depth and preferred memory placement in their manifests.
- App identifiers are validated against length and character requirements.
- Crash diagnostics now show the crash cause, reason, fault address, call stack, and program-counter details, with logs saved for review.
- App closing is more consistent across built-in screens. There's now a dedicated function, and the old _emit() function is made private.
- Crash diagnostics no longer display a QR code without a call stack.
- Improved memory allocation for unrestricted requests.
Event handling:
- Added unified event handling for application, system, and Wi‑Fi events.
- Updated all apps to reflect event handling changes
Wi-Fi:
- Refactored event handling from listener interface to task & event group.
- Added direct Wi‑Fi radio controls and improved event subscriptions.
- Wi‑Fi screens now refresh asynchronously and handle unavailable devices more gracefully.
- Enabled Wi‑Fi by default on in dts files, but radio on/off is still done by code. The main reason was reliable event subscription and consistent devicetree states.
- Improved Wi‑Fi shutdown cleanup and radio-state handling.
Other:
- Renamed the Kernel Display app to Display.
- Moved test projects to the parent project they belong to
- Improved test stability/corectness
- Improved recursive directory deletion by safely ignoring current- and parent-directory entries.
- Update docs
- Auto-select widgets in Launcher and apps with toolbars on devices without touch.
