Enumeration Type Documentation

AccelBandwidth

enum class AccelBandwidth : uint8_t

strong

BMA4 Accelerometer averaging filter configuration These values configure the internal averaging filter to reduce noise.

Higher averaging provides better noise reduction but increases power consumption.

Enumerator
OSR4_AVG1	OSR4 mode with 1 sample averaging (lowest power, highest noise)
OSR2_AVG2	OSR2 mode with 2 samples averaged.
NORMAL_AVG4	Normal mode with 4 samples averaged.
CIC_AVG8	CIC filter with 8 samples averaged.
RES_AVG16	Resolution mode with 16 samples averaged.
RES_AVG32	Resolution mode with 32 samples averaged.
RES_AVG64	Resolution mode with 64 samples averaged.
RES_AVG128	Resolution mode with 128 samples averaged (best noise reduction, highest power)

Examples

/home/runner/work/SensorLib/SensorLib/src/sensor/accelerometer/bma/SensorBMA4XX.hpp.

Definition at line 55 of file sensor/accelerometer/bma/SensorBMA4XX.hpp.

AccelPerfMode

enum class AccelPerfMode : uint8_t

strong

BMA4 Accelerometer performance mode configuration Configures the internal filter behavior for sample averaging.

Enumerator
CIC_AVG_MODE	Averaging filter mode: samples are averaged based on configured bandwidth and ODR.
CONTINUOUS_MODE	Continuous mode: no averaging, raw samples with lower latency.

Examples

/home/runner/work/SensorLib/SensorLib/src/sensor/accelerometer/bma/SensorBMA4XX.hpp.

Definition at line 70 of file sensor/accelerometer/bma/SensorBMA4XX.hpp.

ActivityType

enum class ActivityType

strong

Activity detection type.

Note

This enum defines the different types of activity events that can be detected by the sensor.

Whether or not such attributes exist depends on the specific sensor or the different feature configurations.

Enumerator
STATIONARY
WALKING
RUNNING
UNKNOWN

Definition at line 92 of file sensor/accelerometer/bma/SensorBMA4XX.hpp.

TapType

enum class TapType

strong

Tap detection type.

Note

This enum defines the different types of tap events that can be detected by the sensor.

Whether or not such attributes exist depends on the specific sensor or the different feature configurations.

Enumerator
NO_TAP
SINGLE_TAP
DOUBLE_TAP
TRIPLE_TAP
