Root cause: LVGL9 canvas = lv_image backed by draw_buf with image cache.
Mutating raw uint16_t* buffer without lv_image_cache_drop + lv_draw_buf_invalidate_cache
leaves stale texture (gray/black). Only label (FPS) updated via lv_label_set_text_fmt,
so symptom = FPS counter works, game invisible.
Fix:
- fb_native typed uint16_t* raw RGB565, not lv_color16_t bitfield (endian bug)
- keep lv_draw_buf_t* from lv_canvas_get_draw_buf()
- each frame after gb_run_frame(): invalidate_cache + cache_drop + invalidate
- initial buffer fill check pattern removed, added lines_drawn debug in FPS label
- forward-decl lv_image_cache_drop (not in public SDK headers but firmware exports it)
- requires firmware feature/gameboy-canvas-full-api:
lv_draw_buf_invalidate_cache, lv_image_cache_drop, lv_canvas_get_draw_buf,
lv_image_set_scale/pivot, display resolution
SDK 0.8.0-dev built with IDF 5.5.2 - 0 undefined beyond firmware exports.
Builds to 50K GameBoy.app
Also preserves mDNS browse API from parent branch (Mdns.h/cpp, tt_mdns.h/cpp)
which sits on top of 60764979 'kidsOS-XXXX' mdns init.
- use lv_display_get_*_resolution to compute available area
- apply lv_image_set_scale 2x/3x + pivot center when display large enough
- removes previous comment hack 'avoid non-exported LVGL transform symbols'
- now requires firmware feature/gameboy-canvas-full-api (symbols exported)
SDK: 0.8.0-dev built with IDF 5.5.2, 0 missing symbols
- Mp3Player: increase task stack 4096->6144, prio 5->6, remove taskYIELD causing audio gaps
- VoiceRecorder: configure I2S as stereo for ES7210 (dual mic) like working MicroPython,
then downmix left channel to mono WAV to fix low-pitch mic-like recording
- Single verse fullscreen, auto-advances every minute, tap toggles chrome
- Offline WEB bible split per-book: books.json + 66 bin/idx pairs (~4.1MB)
- bin = NUL-terminated UTF-8 concatenation, idx = {offset,cnum,vnum}
- RAM tiny: loads one book at a time, biggest Psalms ~215KB vs 3.8MB monolith
- Adaptive text scaling by length: <40 ultra-large (Jesus wept), <100 large,
100-200 default, 200-350 small, 350+ compact (Esther 8:9 492c)
- Persistence via user_data_path: progress.txt + favorites.txt (like BookPlayer)
- LVGL fixes: use lvgl_get_text_font(FONT_SIZE_*) - direct montserrat not exported,
no gradients (bg_grad_color not exported), LV_OPA_95 -> OPA_COVER, format-truncation werror silenced
- Deploys to 192.168.68.112 via PUT /api/apps/install (dashboard port 80, dev 6666 closed)

- M5 Unit Modules library + M5 Unit Test app
- Minor fixes for TodoList, TwoEleven, Snake, Brainfuck and Breakout
- Fixed SerialConsole to use the uart controller as it was broken in one of the many updates
- Fixed keyboard input in TwoEleven, Breakout, Magic8Ball and Snake

* New Apps - Lot 1
Trying to mix it up a little with some fun, useful and just weird.
Adds more new apps...
Brainfuck
Breakout
Magic 8 Ball
Todo List
Also re-organised the app name part of main.yml
* Fix build?
* fixes
* and some more
* Update Brainfuck.cpp
* i heard you like fixes with your fixes
* no hard coded paths
Recently the SDK removed GPIO functionality because pins are now exclusively claimed by a driver. That means the GPIO app can't claim pins that are already in use... except when it calls the ESP-IDF driver code directly, which is what the app now does.
* Use single tactility.py and symbolic links
* Fix for MistifyDemo name
* Made snake a bit easier
* Update tactility.py 3.4.0
* Bump Snake version
* Bump version code
- Simplified app registration with a C++ wrapper for the TactilityC.
- Rename the various app classes from `Application` to more specific names like `Calculator` etc.
- Update TactilitySDK to `0.6.0-SNAPSHOT10`: Refactor `tt_app_registration()` for the related changes
- Fix for Diceware app hanging
- Deleted unused `assets/` in HelloWorld app
