Adds STM32/maple HAL layer (XInput, GPIO, serial, keyboard mode) and stm32pintester board configuration. App is linked at 0x08001000 with VECT_TAB_ADDR relocated to support a 4KB custom bootloader at 0x08000000.
Implement reboot_bootloader() via RAM magic (0xDEADBEEFCC00FFEE) for davidgfnet DFU bootloader. Fix RAM to 96KB with 8-byte reservation for reboot flags. Add dfu-util upload command to env.ini.
- Rename config from stm32pintester to jz-stm32-leverless - Rewrite button_mappings[] with 17 active pins verified via pintester (12 of 27 original pin assignments were wrong) - Fix PC12 (A button) stuck/unresponsive: maple framework was using PC12 as USB disconnect pin. Override with -DBOARD_USB_DISC_DEV=NULL - Add SOCD toggle combo (Start + Select + DPadUp cycles SOCD modes) - Add ButtonMappings.md with full mapping table - Set default mode to FGC (default_mode_config = 4)
Change the default vertical SOCD from SOCD_NEUTRAL to SOCD_DIR1_PRIORITY (Up wins over Down). SOCD toggle combo now cycles only the vertical pair (index 1), leaving horizontal always SOCD_NEUTRAL. The cycle now includes DIR1_PRIORITY: DIR1 → NEUTRAL → 2IP → 2IP_NO_REAC → DIR1.
Add pre-clear pass before GPIO reads so multiple pins mapped to the same BTN_* constant use OR semantics: any pressed pin sets the button true; no unpressed pin can overwrite it false. Without this, the last entry in button_mappings[] always wins, breaking secondary mappings. UpdateButtonState now only sets true; false is handled by the pre-clear. Same pattern applied to SwitchMatrixInput, DebouncedGpioButtonInput, DebouncedSwitchMatrixInput, and Pca9671Input for consistency.
setManualReportMode(true) prevents safeSendReport() from firing a blocking USB send on every button/axis setter call. Previously each of the ~21 setters triggered a full sendData() with two USB wait cycles, capping the effective loop rate at ~47Hz. With manual mode, setters only update the in-memory report struct and a single send() at the end of SendReport() does one USB transfer per frame (~1000Hz). Also add patch_usb_polling.py pre-build script to set bInterval=1 in the USBComposite usb_x360w.c endpoint descriptor, raising the USB host polling rate from 250Hz (bInterval=4) to 1000Hz (bInterval=1).
