1. **Display timing fixes for ESP32-S3-LCD-4.3**
- Corrected RGB panel timing parameters (hsync/vsync porch values)
- **Critical fix**: Set `pclk_active_neg = 1` (required for ST7262 panel)
- Added explicit PCLK speed of 16MHz
- These changes fix the blank/unstable display issue on Waveshare 4.3" boards
2. **Added memory diagnostics**
- Prints free heap and PSRAM at boot
- Helps verify PSRAM is properly initialized
3. **Duplicate loop() function**
- The `loop()` function appears twice in the .ino file
- Contains identical code for touch handling, hold-to-silence, and serial commands
- This is a build error waiting to happen
4. **New scaffold script**
- Added comprehensive project scaffolding script (`scaffold.sh`)
- Generates complete multi-target build structure with shared library and per-board drivers
- **ESP32-S3-LCD-4.3 board should now display correctly** (was likely blank before due to wrong timing)
- **Build will fail** due to duplicate `loop()` definition - needs immediate cleanup
- The scaffold script enables rapid project regeneration/setup for new installations
- TOUCH_SDA=17 SCL=18 RST=38 per Waveshare schematic
- GPIO 8/9 conflict with LCD_B0/B3 was blanking the display
- Banner uses BOARD_NAME macro instead of hard-coded E32R35T
- TFT_eSPI #error wrapped in USE_TFT_ESPI guard
- RGB test fills on separate lines so they actually execute
- TOUCH_SDA=17, TOUCH_SCL=18, TOUCH_RST=38 per Waveshare schematic
- GPIO 8/9 were conflicting with LCD_B0/B3, blanking the display
- Boot banner now uses BOARD_NAME macro from BoardConfig.h
1. **Removed entire `loop()` implementation** - The main program loop is now completely empty
2. **Deleted duplicate `silenceAlerts()` functions** - Three identical copies were consolidated into one
3. **Stripped all functionality**:
- Touch handling for different screens (ALERT, DASHBOARD, OFF)
- Hold-to-silence gesture detection
- Display rendering and backlight control
- Serial command processing
⚠️ **This commit breaks the doorbell functionality completely**:
- The device will boot but do nothing (empty loop)
- Touch input won't be processed
- Screen won't update or display anything
- Serial commands won't work
- Alert silencing is defined but never called
This appears to be an incomplete snapshot/refactoring in progress, leaving the application non-functional.
1. **Gutted the main loop** - Reduced from ~80 lines to completely empty
2. **Removed duplicate code** - Eliminated 2 of 3 identical `silenceAlerts()` function definitions that were accidentally created
**Device is now completely non-functional:**
- No display updates or rendering
- Touch input completely ignored
- Alert silencing impossible (function defined but never called)
- Serial commands won't be processed
- Screen stays on/off in whatever state it was in
This is clearly an accidental commit or work-in-progress snapshot. The doorbell will compile and run but do absolutely nothing except the initial setup.
Restores the original behavior from before commit 46b0cb9:
delegates to logic.onTouch() which transitions state to SILENT.
This was a pre-existing bug (undefined function) exposed by the
multi-target refactoring changing compile guard structure.
