Touch and display driver subsystems reworked (and more) (#302)

Browse Source 
- 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
- Refactored `Gui` service to be class and renamed `Gui` to `GuiService`
- Fixed `Statusbar` service: forgot to deregister one of the icons
- Updated `esp_lcd_st7701` to v1.1.3
- `lv_textarea_create()` now automatically registers the hardware keyboard hooks (by wrapping the function)
- Fixed and updated `tactility.py`
- Cleanup of a lot of code
- `BootInitLvglBegin` and `BootInitLvglEnd` are replaced by `LvglStarted` and `LvglStopped`.
- Introduced `tt::service::State` which is accessible via `tt::service::getState()` (and internally via `ServiceInstance`)
- Started replacing `#define TAG` with `constexpr auto TAG = "..";`

# TODOs
- Revisit TinyUSB mouse idea: the bugs related to cleanup seem to be fixed in the library.
- Bug: When a Wi-Fi SSID is too long, then it fails to save the credentials
- Add a Keyboard setting app to override the behaviour of soft keyboard hiding (e.g. keyboard hardware is present, but user wants soft keyboard)
- Add a Keyboard setting app to override the behaviour of soft keyboard hiding (e.g. keyboard hardware is present, but the user wants to use a soft keyboard)
- HAL for display touch calibration
- Start using non_null (either via MS GSL, or custom)
- `hal/Configuration.h` defines C function types: Use C++ std::function instead
- Fix system time to not be 1980 (use build year as minimum)
- Fix system time to not be 1980 (use build year as a minimum). Consider keeping track of the last known time.
- Use std::span or string_view in StringUtils https://youtu.be/FRkJCvHWdwQ?t=2754
- Fix bug in T-Deck/etc: esp_lvgl_port settings has a large stack size (~9kB) to fix an issue where the T-Deck would get a stackoverflow. This sometimes happens when WiFi is auto-enabled and you open the app while it is still connecting.
- Mutex: Implement give/take from ISR support (works only for non-recursive ones)
- Extend unPhone power driver: add charging status, usb connection status, etc.
- Expose app::Paths to TactilityC
- Experiment with what happens when using C++ code in an external app (without using standard library!)
- Make a ledger for setting CPU affinity of various services and tasks
- CrashHandler: use "corrupted" flag
- CrashHandler: process other types of crashes (WDT?)
- Call tt::lvgl::isSyncSet after HAL init and show error (and crash?) when it is not set.
- Create different partitions files for different ESP flash size targets (N4, N8, N16, N32)
- Call tt::lvgl::isSyncSet after HAL init and show an error (and crash?) when it is not set.
- Create different partition files for different ESP flash size targets (N4, N8, N16, N32)
- T-Deck: Clear screen before turning on blacklight
- T-Deck: Use knob for UI selection?
- Crash monitoring: Keep track of which system phase the app crashed in (e.g. which app in which state)
@ -26,28 +26,27 @@
- Show a warning screen when a user plugs in the SD card on a device that only supports mounting at boot.
- Localisation of texts (load in boot app from sd?)
- Explore LVGL9's FreeRTOS functionality
- External app loading: Check version of Tactility and check ESP target hardware, to check for compatibility.
- External app loading: Check version of Tactility and check ESP target hardware to check for compatibility.
- Scanning SD card for external apps and auto-register them (in a temporary register?)
- Support hot-plugging SD card
- All drivers (e.g. display, touch, etc.) should call stop() in their destructor, or at least assert that they should not be running.
- Use GPS time to set/update the current time
- Investigate EEZ Studio
- Remove flex_flow from app_container in Gui.cpp
# Nice-to-haves
- Give external app a different icon. Allow an external app update their id, icon, type and name once they are running(and persist that info?). Loader will need to be able to find app by (external) location.
- Give external app a different icon. Allow an external app to update their id, icon, type and name once they are running (and persist that info?). Loader will need to be able to find app by (external) location.
- Audio player app
- Audio recording app
- OTA updates
- T-Deck Plus: Create separate board config?
- Support for displays with different DPI. Consider the layer-based system like on Android.
- If present, use LED to show boot/wifi status
- Capacity based on voltage: estimation for various devices uses linear voltage curve, but it should use some sort of battery discharge curve.
- Capacity based on voltage: estimation for various devices uses a linear voltage curve, but it should use some sort of battery discharge curve.
- Statusbar widget to show how much memory is in use?
- Wrapper for Slider that shows "+" and "-" buttons, and also the value in a label.
- Wrapper for lvgl slider widget that shows "+" and "-" buttons, and also the value in a label.
- Files app: copy/paste actions
- On crash, try to save current log to flash or SD card? (this is risky, though, so ask in Discord first)
- On crash, try to save the current log to flash or SD card? (this is risky, though, so ask in Discord first)
- Support more than 1 hardware keyboard (see lvgl::hardware_keyboard_set_indev()). LVGL init currently calls keyboard init, but that part should probably be done from the KeyboardDevice base class.
