Gait Analysis IoT

A dual-core Raspberry Pi Pico W streams IMU data at 100 Hz, driven by an RP2040 hardware alarm and a lock-free SPSC ring buffer. Sensor acquisition is isolated from Wi-Fi/lwIP networking, with UDP streaming using redundant sample batches and explicit retransmission requests. A PySide6 app repairs lost packets (NACK-based) and plots the IMU data live.
