New port for the 240x284 ESP32-S3-Touch-LCD-1.83. Unlike the existing ports this panel is an ST7789P TFT driven over 4-wire SPI (not a QSPI AMOLED) and has no XCA9554 IO expander: the LCD/touch reset lines are plain GPIOs and the backlight is a PWM-dimmed LED string. Touch (CST816D), PMU (AXP2101) and IMU (QMI8658) match the AMOLED-1.8. - boards/waveshare_lcd_183/: display (Arduino_ESP32SPI + Arduino_ST7789, LEDC backlight), CST816 touch, AXP2101 power via PKEY, QMI8658 imu stub, caps, board_init. Pins from Waveshare's official demo. - platformio.ini: [env:waveshare_lcd_183]. - ui.cpp: add a "tiny" 240x284 layout breakpoint and make the usage screen fonts/logo responsive. Existing boards render unchanged. - tools/shot_png.py: ffmpeg-free framebuffer -> PNG capture helper. - docs: note that 4-wire SPI TFT panels are now supported.

Personal customization on top of the LCD-1.83 board port (German labels, opinionated layout — not intended for the upstream PR). UI (ui.cpp, theme.h): - Rebuilt the usage screen: header (logo + "Usage" wordmark + live clock), big SESSION % with a pace marker (elapsed share of the 5h window) and an "Ueber/Unter Tempo" verdict, a "LETZTE 7 TAGE" sparkline, a WEEKLY row (flex layout, equal gaps around the bar) and the status line. - No battery icon: this SKU ships without a cell (has_battery=false in caps.cpp / board.h). Fonts: - Generated Tiempos 18 (wordmark), Mono 11 (small text) and Mono 15 (status) from assets/ via lv_font_conv, incl. German glyphs (Ue/middot). Data + protocol (data.h, main.cpp, daemon): - UsageData gains clock[9] + day7[7]; parse_json reads "t" and "d7". - Clock advances locally from a seconds-accurate host sync (HH:MM:SS) so it flips at the real minute boundary instead of lagging the 60s poll. - Daemon sends "t" (HH:MM:SS) and "d7" (7-day token totals parsed from ~/.claude/projects/*.jsonl, normalized to the busiest day; index 6 = today).

Personal: redesigned usage screen (live clock + 7-day history)

What
Adds a board port for the Waveshare ESP32-S3-Touch-LCD-1.83 (240×284).
This is the first SPI TFT port — the panel is an ST7789P driven over 4-wire SPI rather than a QSPI AMOLED, and the board has no XCA9554 IO expander (LCD/touch resets are plain GPIOs, backlight is a PWM-dimmed LED string). Touch (CST816D @ 0x15), PMU (AXP2101) and IMU (QMI8658) match the AMOLED-1.8, all on the same I2C bus.
Changes
firmware/src/boards/waveshare_lcd_183/— new per-board folder (display, touch, power, imu, caps, board_init). Display usesArduino_ESP32SPI+Arduino_ST7789; brightness maps onto an LEDC PWM backlight. Pins taken from Waveshare's official demo (waveshareteam/ESP32-S3-Touch-LCD-1.83).firmware/platformio.ini—[env:waveshare_lcd_183].firmware/src/ui.cpp— adds a thirdcompute_layout()breakpoint for small 240×284 screens (smaller fonts + shrunk logo) and makes the usage-screen fonts responsive (the Bluetooth screen already worked this way). The two existing boards (480×480, 368×448) render identically — they keep their current font choices.tools/shot_png.py— small ffmpeg-free framebuffer→PNG capture helper (complementsscreenshot.sh).docs/porting/adding-a-board.md— note that 4-wire SPI TFT panels are supported, with this board as the reference.Testing
Built and flashed on real hardware (
pio run -e waveshare_lcd_183). Boot is clean (display, CST816 touch, AXP2101, QMI8658 all init), the splash and usage screens render correctly at 240×284, the daemon pairs over BLE and live usage shows. Note: row offset is 0 on this panel (Waveshare's demo uses 20, which left the top ~20 rows unwritten here).🤖 Generated with Claude Code
