December 2025, PX4-Autopilot: Implemented IST8310J device ID support in the IST8310 driver to enable compatibility with both IST8310 and IST8310J sensors. Added device identification and stability improvements during probe/reset; due to flash size constraints, cross-axis compensation was removed in favor of leveraging the existing magnetometer calibration workflow. Introduced caching of the WAI register value to avoid redundant I2C reads during the reset wait state, reducing bus traffic and startup latency. All changes align with PX4 magnetometer calibration framework and were validated on Raspberry Pi with I2C for both IST8310 and IST8310J devices.
