- 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`)
- 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`
- WiFi Connect app is now hidden by default, but accessible at the bottom of the WiFi Manage app when WiFi is turned on.
- WiFi service now turns on WiFi when calling connect() and WiFi is not on.
- Removed `blocking` option for `service::loader::startApp()`. This feature was unused and complex.
- Various apps: Moved private headers into Private/ folder.
- Various apps: created start() function for easy starting.
- Added documentation to all TactilityC APIs
- Refactored various `enum` into `class enum`
- Refactor M5Stack `initBoot()` (but VBus is still 0V for some reason)
