Sensor: bme280

Overview

This sample demonstrates how to read temperature, pressure, and humidity data from a Bosch BME280 sensor using the Zephyr sensor driver.

The OpenAir wrapper is intended for Atmosic hardware and includes test targets for MikroE Weather Click shield configurations over both I2C and SPI.

For more details, refer to zephyr/samples/sensor/bme280/README.rst.

Requirements

• Atmosic ATMBTCSTAG-3405 Tag Reference Design

• MikroE Weather Click shield connected over I2C or SPI

Building and Running

This sample is built from openair/samples/sensor/bme280. The source code can be found under zephyr/samples/sensor/bme280.

Build command (I2C):

west build -p always -b ATMBTCSTAG-3405 openair/samples/sensor/bme280 --sysbuild -T samples.sensor.bme280.atm

Build command (SPI):

west build -p always -b ATMBTCSTAG-3405 openair/samples/sensor/bme280 --sysbuild -T samples.sensor.bme280.atm.spi

Flash command:

west flash --no-rebuild --device <DEVICE_ID> --jlink --fast_load [--erase_flash]

Configuration

The OpenAir sample provides a board overlay under boards/app.overlay for an I2C-connected BME280, while the test targets select the appropriate shield configuration for the MikroE Weather Click.
