This repository is a portfolio mirror extracted from the Software-Solaris codebase (Solaris, UVigo Aerotech).

It contains the BMP390 pressure sensor driver and the minimal surrounding code required to showcase it as a standalone project.

The BMP390 is a high-precision barometric pressure sensor from Bosch, typically used for altitude estimation and environmental sensing in embedded systems.

This driver is designed for ESP32-S3 targets and focuses on:

• SPI communication
• Device initialization + configuration
• Burst raw data acquisition
• Pressure/temperature compensation
• Altitude estimation (pressure-based)
• Practical integration into embedded firmware projects

The detailed technical documentation for the driver lives here:

BMP390/components/pressure_sensor_driver/README_BMP390.md

If you want to understand:

• Register configuration (ODR / oversampling)
• Burst reads
• Raw-to-compensated formulas
• Implementation details and usage patterns
  ... go directly to that file.

• Language: C
• Target: ESP32-S3
• Framework: ESP-IDF

• BMP390 driver source code (SPI)
• Configuration + measurement logic
• Raw data reading utilities
• Compensation and filtering pipeline (as implemented in Solaris)

This driver was developed with a strong focus on real-hardware validation:

• Tested on real ESP32-S3 hardware
• Verified SPI communication and device ID
• Verified raw data variability and compensated output behavior

• Driver End-to-End Developer: Óscar Barja Lorenzo
