Rework the Gyro Tilt screen (and the tilt->RGB lightbar) using the DS5's own factory IMU calibration, and fix two long-standing tilt-dot quirks. All three are display-only — the host input report (every gyro + accel axis) is still forwarded byte-for-byte, so in-game motion is unaffected. - Calibration: parse feature report 0x05 (already cached by bt.cpp) into per-axis bias + sensitivity and apply (raw-bias)*sens to the accel the tilt visuals use, keeping the +-8192 == 1g scale. Re-read per connection so it tracks across the 4 pairing slots; sanity-gated with raw fallback. New side-effect-free bt_peek_feature() accessor (never issues an L2CAP request, safe to poll). Parse/apply mirror SDL's SDL_hidapi_ps5.c (zlib). - Centred when flat: drive the dot from X (roll) + Z (pitch) instead of X + Y. Gravity rests on Y when flat, so the old Y mapping pegged the dot to the bottom edge at rest; it now sits centred. - Direction: negate both axes so the dot follows the tilt (tilt left -> dot left, tilt forward -> dot up) instead of mirroring it. Also fold in this session's charge-ETA robustness fix: cap each timed 10% step at 30 min and take the median over the last 5 steps, so one slow step can't balloon the estimate (was reading ~222m at 70% off a single ~47-min step). Shares src/oled.cpp with the gyro work. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
