ESP32 Sensor Bring-Up Suite

PlatformIO projects to exercise three sensors with an ESP32 DevKit (Arduino framework):

• ADXL372 (±200 g accelerometer) – env:adxl372
• ISM330DHCX (6‑DoF IMU) – env:ism330dhcx
• LPS28DFW (barometer) – env:lps28dfw

Wiring (ESP32 VSPI defaults)

• SCK 18, MOSI 23, MISO 19, CS 5 (change per file if needed).
• Power: 3V3, GND.
• Optional interrupts:
  • ADXL372: INT1=GPIO4, INT2=GPIO15
  • ISM330DHCX: INT1=GPIO4, INT2=GPIO15
  • LPS28DFW: none required (uses polling/FIFO)

Build & Flash

pio run -e adxl372 --target upload
pio run -e ism330dhcx --target upload
pio run -e lps28dfw --target upload

Serial monitor at 115200:

pio device monitor -e adxl372   # or ism330dhcx, lps28dfw

Runtime menus (hotkeys)

• ADXL372: live stream, FIFO stream/trigger, HPF toggle, ODR/BW cycle, unit toggle (g↔m/s²), CSV/human toggle, 200‑sample bias calibration, self‑test, activity/inactivity demo.
• ISM330DHCX: live stream of accel/gyro/temp + pitch/roll, CSV/human toggle, accel & gyro FS cycle, ODR cycle, FIFO dump, 256‑sample bias calibration, self‑test pulse.
• LPS28DFW: live pressure/temp (optional altitude), CSV/human toggle, ODR cycle, low‑noise toggle, smoothing filter toggle, set sea‑level reference from current pressure, FIFO stream on/off + dump.

Notes

• Bias calibrations assume the board is stationary during capture.
• Live print rate is ~100 Hz for motion sensors; sensor ODR can be higher.
• Altitude uses the standard barometric formula; set sea‑level ref (s) for best accuracy.
