BME680 driver test
About
This is a test application for the BME680 driver. This driver depends on the Bosch Sensortech BME680 driver.
Usage
This test application will initialize one or more BME680 devices to output the following every 5 seconds:
- Temperature
- Humidity
- Pressure
- Resistance value (depending on VOC gas)
The driver can use either fixed-point or floating-point arithmetic for all
conversions. By default fixed-point arithmetic is used. To use floating-point
arithmetic, the bme680_fp module has to be enabled. This can be done in the
test application by setting the environment variable ENABLE_FP:
ENABLE_FP=1 make BOARD=... -C tests/drivers/bme680
Interface
BME680 sensors can be used with I2C and/or SPI. Which interface is used by
which BME680 sensor is defined in the bme680_params parameters. The
respective implementation is enabled by the modules bme680_i2c and
bme680_spi.
Which implementation is used for the test application is defined by the
DRIVER environment variable. By default bme680_i2c is used. To use
bme680_spi, the DRIVER variable could be set at the make command line:
DRIVER=bme680_spi make BOARD=... -C tests/drivers/bme680
It is also possible to use I2C as well SPI simultaneously in the test application:
DRIVER=bme680_spi bme680_i2c' make BOARD=... -C tests/drivers/bme680
