From the project

Device to test cyclic load on piezoelectric sensors

This directory contains the ESP32 firmware for PiezoTester V2.0. It is built with ESP-IDF and implements the real-time measurement, calibration, electromagnet control, session logic, and UART command interface used by the desktop application.

- Reads the ADS1219-based load path - Reconstructs piezoresistive sensor resistance - Calibrates the load cell and the sensor path - Drives the electromagnet through PWM - Learns an empirical PWM-to-load model - Executes standard, ramp, and hysteresis tests - Stores calibration data and learned model points in NVS - Streams results and status to the…
