BMI160 Sensor API

Sensor overview

The small, low power BMI160 is a low noise 16-bit IMU designed for mobile applications such as AR or indoor navigation, providing highly accurate sensor data and real-time sensor data. The low current consumption of BMI160 enables always-on applications in battery-driven devices. This sensor features a configurable on-chip interrupt engine which provides motion-based gesture recognition and context awareness as always-on background functions.

Target Application

• Augmented reality and immersive gaming
• Indoor navigation
• 3D-scanning / indoor mapping
• Advanced gesture recognition
• Immersive gaming
• 9-axis motion detection
• Air mouse applications and pointers
• Pedometer / step counting
• Advanced system power management for mobile applications
• Optical image stabilization of camera modules
• Free-fall detection and warranty logging

Features

• Any-motion detection (accelerometer)
• Significant motion detection (accelerometer)
• Step detector (accelerometer)
• Tap sensing (accelerometer)
• Orientation recognition (accelerometer)
• Flat detection (accelerometer)
• Low-G / Free-fall detection (accelerometer)
• High-G detection (accelerometer)
• Slow-motion alert / No-motion interrupt (accelerometer)
• Data ready detection (accelerometer, gyroscope and external sensors)
• PMU trigger (gyroscope)
• FIFO interrupts ((accelerometer, gyroscope and external sensors)

 

현재 사용하고 있는 model : Cypress사의 PSoC6 MCU CY8C6347BZI-BLD53

int8_t bmi160_read_step_counter(uint16_t *step_val, const struct bmi160_dev *dev)
===================================================================================

int8_t  MotionSensor_ReadSteps(uint16_t* steps)
{
    return bmi160_read_step_counter(steps,  &sensor);
}

uint16_t stepCount = 0;

MotionSensor_ReadSteps(&stepCount);

read step 함수만 사용하여, 현재 코드에선 스탭수만 추출하여 사용중.
