Macro Definition Documentation

BARO_ALTIMETER_DEBUG

#define BARO_ALTIMETER_DEBUG

This class encompasses all functions to create a barometric altimeter for the drone, based on Adafruit's BMP388 sensor library.

This class is responsible for:

• Initializing and configuring the sensor
• Reading pressure and temperature
• Filtering raw measurements
• Computing change in altitude from T/O location
• Computing vertical speed

The library applies a median filter to the data to smooth out measurements during 'hover' states, and based on thresholds, returns more responsive readings during altitude changes.

Computes vertical speed based on a backwards difference formula
