| Feature | Description | |---------|-------------| | | Up to 5 simultaneous touch points (typical for mid‑range devices). | | Gesture Library | Pre‑programmed gestures: single‑tap, double‑tap, swipe (4‑direction), pinch‑in/out, and rotate. | | Self‑Calibration | Adaptive baseline tracking that compensates for temperature drift and environmental humidity. | | Low‑Power Modes | “Idle” (sensor scan 30 Hz, power ≈ 1 mW) and “Sleep” (sensor off, wake‑on‑touch via edge detection, power ≈ 0.2 mW). | | Noise Immunity | Frequency‑domain filtering, adaptive thresholds, and EMI rejection tuned for automotive environments. | | Diagnostic Commands | A small set of I²C registers for raw electrode data, baseline values, and firmware version. | | Secure Update | Firmware image signed with an OEM‑specific key; the boot loader verifies the signature before flashing. | | Region‑Specific Tuning | Parameter tables (e.g., touch‑thresholds, gesture sensitivity) selectable at boot based on a hardware strap or EEPROM flag. |
