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
…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
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
