- Added PWM brightness control to ST7796 driver (0-100%)
- Implemented hardware sleep mode for ST7796 (saves ~150mA)
- Added sleep/wake functions preserving framebuffer and settings
- Implemented timer-based inactivity detection (checks every 10s)
- Auto-sleep after 5 minutes of no user input
- Touch controller remains active during TFT sleep for instant wake
- E-ink display also sleeps after timeout, requires re-init on wake
- Added hardware_pwm library dependency to CMakeLists.txt
- Brightness and sleep/wake methods exposed through display abstraction layer
- Added INPUT_FRAME_TICK event type to input_event.h
- Added wants_frame_updates() virtual method to Game base class
- Implemented frame tick logic in main loop (basic1.cpp and emulator/main.cpp)
- Added Lua bindings: game.set_frame_updates(bool) and INPUT.FRAME_TICK
- Updated LuaGame to support frame updates via registry flag
- Updated ball.lua to use continuous frame updates for smooth animation
- Both hardware and emulator now support continuous animation for physics/games
Store game names and descriptions in persistent LuaGameFactoryData
structure instead of local stack variables to prevent dangling pointers.
Same fix as emulator version.
- Created emulator-specific lua_game_emulator.cpp using filesystem instead of FatFS
- Created lua_game_loader_emulator.cpp to scan games/lua_examples directory
- Updated CMakeLists.txt to include Lua 5.4 engine and bindings
- Updated to SFML 3.0 API compatibility (event handling, sprite initialization)
- Updated Game class to use public members for Lua bindings
- Updated GameLauncher to use std::function for lambda captures
- Added continuous 60 FPS rendering for smooth display
- Emulator now loads and runs all three example Lua games
- Integrated Lua 5.4 engine (32-bit mode for embedded ARM)
- Created LuaGame wrapper class implementing Game interface
- Added C++ bindings exposing renderer, game state, and input to Lua
- Implemented SD card loader for automatic .lua game discovery
- Updated GameLauncher to support std::function for lambda captures
- Made Game class members public for Lua bindings access
- Added example Lua games: counter, snake, bouncing ball
- Included comprehensive API documentation
Games can now be written as .lua text files on SD card and loaded
without recompilation. Build size: 747KB UF2, Lua VM uses ~50-80KB RAM.
