Core requirements:

Sync logic: A 200 Hz global sync pulse must be generated by an ESP32-P4 hardware timer.

Timestamp binding: At the hardware level, pressure (5 ch), attitude (6-axis), and audio (per sample) must all be tagged with the same 64-bit nanosecond global timestamp.

Phase control ...

I’m working on a wearable device that uses an ESP32-P4 as the main controller to achieve high-precision, synchronized acquisition of 720P/50FPS video, audio, fingertip pressure, and hand pose. A hardware timer will generate a 200Hz global sync pulse; pressure (5 channels), pose (6-axis), and audio ...
