…trings and each other

-Find and remove strings not used in GUI anymore
-Find and add strings used in GUI but not in files (add <FILL> as placeholder text)
-Update english reference texts in translation files when needed

just a development tool

Add flashable MockUI firmware with build target, manifest, and boot/main
entry points. Fix two issues blocking firmware operation:

1. Icon MemoryError: Switch icon format from ARGB8888 to A8 (alpha-only)
   in icon.py. The pattern bytes from btc_icons.py are used directly as
   A8 image data (zero heap allocation, references frozen bytecode in
   flash). Color is applied via LVGL image_recolor style. This eliminates
   the 3120-byte contiguous allocation that failed on the fragmented
   245KB MicroPython heap.

2. Missing i18n translations: Create translations_embedded.py with
   English translations as a Python dict. Modify i18n_manager.py to fall
   back to embedded translations when JSON files aren't available (frozen
   firmware can't include JSON). Simulator still uses JSON-first loading.

…ap; added size sanity check

-After refactoring to A8 instead of ARGB format that parameter is not needed anymore

-W/o size check unintended memory access could be possible

- Replace JSON-based i18n with efficient binary format for embedded systems
- Add lang_compiler.py for JSON→binary conversion with validation
- Implement flash filesystem storage (/flash/i18n/) for runtime language loading
- Update i18n_manager.py to use binary files with zero RAM string storage
- Add build system integration with automatic i18n compilation
- Support both embedded (data/lang/) and user-added (flash) language files
- Add comprehensive translation key management and validation
- Update documentation with binary format specifications

Technical changes:
- Binary format: 12-byte header + offset index + null-terminated strings
- Search paths: data/lang (embedded) → /flash/i18n (user languages)
- Lazy loading: strings read directly from flash on demand
- Fallback system: missing translations use default language
- Build integration: make mockui now includes build-i18n step

Known issue: Firmware hangs during boot, possibly due to early flash access

…8n_manager.py

…e + added tests for it

…ns with lang_compiler + added tests for it

pathlib and datetime calls

get_language() can return None, which needs proper handling in gui

… changes in i18n_manager.py

-removed unnecessary folders/files from build process: only i18n folder or build folder are used for files created during build
-language files are stored during build in FAT filesystem, not littleFS (as this matches STM32 Micropython default)
-made i18n_manager handle the fact that FAT uses upper case filenames correctly
-re-added get_language_name (should not have been removed -> not used by i18n itself, but by language_menu)

… from file

-needed to add language name in binary file (read during conversion from JSON)

this is a general tool for debugging, not specific to MockUI hence, moved in the general /tool folder

to more clearly separate infrastructure/code from data files

To match current design, workflow and implementation status

E.g. for debugging

Add flashable MockUI firmware with build target, manifest, and boot/main
entry points for the STM32F469 Discovery board.

Key changes:
- Add mockui_fw/ scenario with boot.py and main.py entry points
- Add manifest and Makefile build target for 'make mockui'
- Fix icon MemoryError: switch from ARGB8888 to A8 alpha-only format
  (eliminates 3120-byte allocation that failed on fragmented heap)
- Add size sanity check to icon bitmap creation
- Fix status bar crash when no language is available
- Enable USB at startup for debugging

Replace JSON-based i18n with an efficient binary format optimized for
MicroPython on resource-constrained embedded systems.

- Add lang_compiler.py for JSON-to-binary conversion with validation
- Binary format: 12-byte header + offset index + null-terminated strings
- Implement flash filesystem storage (/flash/i18n/) for runtime loading
- Lazy loading: strings read directly from flash on demand (zero RAM)
- Fallback: missing translations use default language
- MicroPython-compatible: use os module instead of platform/pathlib
- Remove translations_embedded.py in favor of binary files

Add build system integration for compiling and deploying i18n binary
files to the STM32F469 Discovery board's flash filesystem.

- Add make_fat_image.py for creating FAT filesystem images
- Add merge_firmware_flash.py for combining firmware with flash data
- Integrate i18n compilation into 'make mockui' build pipeline
- Change precompiled filesystem from LittleFS to FAT (matches STM32
  MicroPython default)
- Handle FAT uppercase filename convention in i18n_manager.py
- Add language name lookup from binary file metadata
- Organize JSON source files into dedicated languages/ folder

Rewrite i18n README to match current binary format design, covering
architecture, build workflow, file format specification, and usage
instructions for adding new languages.

- Unit tests for lang_compiler.py (binary compilation, validation)
- Unit tests for i18n_manager.py (loading, fallback, filesystem)
- Integration tests for end-to-end i18n workflow
- Hardware-in-the-loop tests for STM32F469 device validation
- Shared test fixtures via conftest.py

…ggo83/specter-playground into PortMockUIUpdatesToDiscoBoard

…ageFiles-Tool

Move sync_i18n.py from i18n/helpers/ to tools/ alongside the other
build-time utilities, and update it substantially:

Key detection:
- Add recognition of all i18n access patterns beyond t("KEY"):
  i18n["KEY"], i18n("KEY"), i18n_manager["KEY"], i18n_manager("KEY"),
  single- and double-quote variants of all of the above

Language file discovery:
- Use extract_language_code_from_filename() from lang_compiler.py to
  enforce naming conventions (specter_ui_XX.json); non-conforming files
  are skipped with a warning instead of silently included

CLI interface:
- Rename --i18n-dir to --languages-dir (points directly at languages/)
- Default log output goes to build/ instead of inside the source tree

Logging:
- Rewrite to write logs incrementally (open/write/close per entry),
  so partial logs survive crashes
- Log files are initialised with a header before any work starts;
  if --dry-run, "*** DRY RUN — no changes will be made ***" appears
  as the second line, not buried at the end
- Always write logs, including during dry-run

FILL_PLACEHOLDER:
- Define FILL_PLACEHOLDER = "<FILL>" in lang_compiler.py as the single
  source of truth; imported by sync_i18n.py to keep them in sync
- Add runtime check in i18n_manager.t(): if the resolved translation
  equals FILL_PLACEHOLDER, fall back to English; if even English has
  it, return STR_MISSING — the placeholder never reaches the UI

Build integration:
- Add sync-i18n Makefile target (runs --dry-run to detect drift without
  modifying files); make it the first dependency of build-i18n so every
  build logs the current sync state
- Update README.md: file structure, per-component docs, build targets,
  and a dedicated sync tool section with CLI examples
