- RLCD device.properties: DefaultDark (focus UI visible), fontSize 18
(+28% vs 14: small 10->14, default 14->18, large 18->24, icons 16->20/36->48)
- ST7305 driver: honor invertColor config (was ignored), call
esp_lcd_panel_invert_color after init
- DisplayDevice: add supportsInvertColor + set/get, and
supportsMonochromeThreshold/set/get (ST7305 only)
- EspLcdDisplay: implement invert via panelHandle, and mono threshold via
global g_mono_threshold shared with esp_lvgl_port
- DisplaySettings: new fields invertColor (default true to preserve current
inverted look) and monochromeThreshold (default 60 best for DefaultDark per
user testing, range 20-230)
- Lvgl.cpp: apply invert + threshold at boot from settings
- Display app: add Invert colors switch (if supportsInvertColor) + Mono
threshold slider with live preview and persistence
- esp_lvgl_port_disp.c (components override for hash mismatch): fix B/W
conversion
BEFORE: blue >16 only -> crushed colors, no gray handling
AFTER: proper luminance Y=0.299R+0.587G+0.114B with adjustable threshold
(default 60), no Bayer dithering dots. Crisp text on reflective
- Launcher/button/list wrappers reverted to stock DefaultDark (no white
focus hacks) per user request - focus UI now uses default outline which
survives luminance threshold
Verified on waveshare-esp32-s3-rlcd /dev/cu.usbmodem1101:
- Build 2877200 bytes, flash hash verified
- Invert toggle works, threshold slider live (60 best per test)
- Font bump visible, focus UI visible for button navigation
- No dithering dots

- Fix DTS I2S pinmap to RLCD correct pins (mclk 16, bclk 9, ws 45, tx 8, rx 10) resolving GPIO5 conflict with display DC
- Port ES8311 DAC and ES7210 mic ADC init from working MicroPython audio_util.py
- Fix I2S DMA OOM by reducing to 6x160 and RX fallback to TX-only
- Fix MCLK multiple for 12.288MHz family (16k->768 exact) to avoid robot sound
- Avoid ES8311 reclock glitch for 16k rate to eliminate pop
- Clean log spam (file lock once, listDir DEBUG, I2S DEBUG) that caused UART jitter
- VoiceRecorder: request stereo from ES7210 and downmix left channel to fix mic-like low pitch
- DTS: migrate i2c0 from legacy esp32-i2c to esp32-i2c-master to avoid IDF CONFLICT warning (driver_ng vs old driver) which could stall boot
- Configuration.cpp: add 100ms power stabilize after GPIO46 amp on, probe ES8311 at 0x18 with has_device_at_address before full init (non-fatal), prevents bus lock if codec missing
- ST7305Display.cpp: add 150ms after reset + 50ms after init, prevents freeze on fast boot where SPI transaction too early (observed stuck on weird state)
Build 0x2b79c0 -> 0x2b79c0 with I2C master, ES8311 now initializes, display stable
