96089c168f Verify internal temp sensor is live via CPU stress test 
- temp sensor confirmed responsive to die heating (27.6 -> 28.6 C under load)
- document quantization/calibration: readout sticks to ~1C steps ending in .6
  (inherent to ESP32-H2 internal sensor, not a bug)
- keep CPU_STRESS_TEST as a debug toggle (default off)

b6a7e082b1 Document planned battery (low) and Bluetooth (Matter joined) icon behavior 2026-09-24 17:58:09 +00:00

b5cf59b39a Complete icon map: Bluetooth (f13 bit3) and battery (f13 bit4) with °C composition 
- probed f[13] on blank panel: bit3=Bluetooth, bit4=battery icon,
  0x05=°C, 0x06=°F, bits5-7 unused
- combos verified live: 0x0D (°C+BT), 0x15 (°C+bat), 0x1D (°C+BT+bat)
- add ICON_* constants to temphummon.c; restore as active build
- update PROJECT_MEMORY.md with complete f[13] icon table

d9bac7cf28 Document icon-probe results; keep iconfinder bitprobe as artifact 
Probed remaining frame bytes for Bluetooth/power icons on a blank panel:
- found cross-wired glyph dots (byte0 bit7, byte4 bit7) and an I2C timeout
  (byte8 bit4), but no standalone icon bits
- waveshare reference does not drive these icons; likely multi-bit or
  unpopulated on the glass (cosmetic, deprioritized)
- restore temphummon.c as the active firmware build in CMakeLists

ebbeffa432 Add bit-probe results, decimal point/percentage bit map, and working temperature+humidity display 
- bitprobe.c: interactive single-bit probe that discovered the display glyph
  layout and the decimal point / percent sign bit positions
- temphummon.c: render top line '188.8°C' and bottom '88.8%' using the
  verified decimal points (f[4], f[8] bit5) and percent sign (f[10] bit5)
- PROJECT_MEMORY.md: document full frame layout + empirical bit map
- README: add wiring table and project memory pointer
- add Waveshare reference zip and flake.lock
