Adolfo Reyna	b16211f148	Fix SD card integration and Lua game loading ... - Fix SD card MISO pin (was using display MISO instead of SD MISO) - Add FatFS mounting after SD card initialization - Restore SPI baudrate on all SD init failure paths - Add case-insensitive .lua file extension check - Filter out hidden 8.3 filename entries - Add SPI speed management functions for shared SPI bus - Wrap all FatFS operations with SPI speed switching - Restore display SPI speed (32 MHz) after SD operations - Add debug output to Lua game loader This fixes slow display refresh when SD card is present and enables reliable Lua game loading from SD card /games directory.	2026-02-07 19:31:38 -05:00
Adolfo Reyna	2a472fc29f	Add frame tick system for continuous animation ... - 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	2026-02-07 13:20:10 -05:00
Adolfo Reyna	e6e4eca188	Add Lua 5.4 scripting integration for dynamic game loading ... - 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.	2026-02-07 11:56:03 -05:00
