BMP3xx - Barometric Pressure Sensor

Description

Driver for the Bosch Sensortec BMP3xx barometric pressure sensor.


BMP3xx example

Basic example to perform pressure measurement:

#include "sl_i2cspm_instances.h"
#include "sl_bmp3xx.h"

  int main( void )
  {

    ...

    float pressure;
    int8_t result;

    result = sl_bmp3xx_init(sl_i2cspm_sensor_env);

    if (result != SL_STATUS_OK) {
      return SL_STATUS_FAIL;
    }

    result = sl_bmp3xx_measure_pressure(sl_i2cspm_sensor_env, &pressure);

    if (result != SL_STATUS_OK) {
      return SL_STATUS_FAIL;
    }

    ...

  }
