Download and install the BMX160 Library. (About how to install the library?)
Communication Protocol Description
The BMX160 sensor communicates with the main controller via the I2C protocol. The Board Overview section lists the I2C Clock (SCL) and I2C Data (SDA) pins for connection.
API Description
The DFRobot_BMX160 library provides the following API functions:
class DFRobot_BMX160 {
/*
* @function Gyroscope enum range, unit: G
*/
typedef enum{
eGyroRange_2000DPS, /*Gyroscope sensitivity at 2000dps*/
eGyroRange_1000DPS, /*Gyroscope sensitivity at 1000dps*/
eGyroRange_500DPS, /*Gyroscope sensitivity at 500dps*/
eGyroRange_250DPS, /*Gyroscope sensitivity at 250dps*/
eGyroRange_125DPS /*Gyroscope sensitivity at 125dps*/
}eGyroRange_t;
/*
* @function Accelerometer enum range, unit, m/s^2
*/
typedef enum{
eAccelRange_2G, /* Macro for mg per LSB at +/- 2g sensitivity (1 LSB = 0.000061035mg) */
eAccelRange_4G, /* Macro for mg per LSB at +/- 4g sensitivity (1 LSB = 0.000122070mg) */
eAccelRange_8G, /* Macro for mg per LSB at +/- 8g sensitivity (1 LSB = 0.000244141mg) */
eAccelRange_16G /* Macro for mg per LSB at +/- 16g sensitivity (1 LSB = 0.000488281mg) */
}eAccelRange_t;
/*
* @function reset sensor
* @Return true if it succeeds
*/
bool softReset();
/*
* @function init sensor
* @Return true if it succeeds
*/
bool begin();
/*
* @function set gyroscope range, unit: G
* @Parameter One variable from eGyroRange_t
*/
void setGyroRange(eGyroRange_t bits);
/*
* @function set accelerometer range, unit: m/s^2
* @Parameter One variable from eAccelRange_t
*/
void setAccelRange(eAccelRange_t bits);
/*
* @function Get data of accelerometer, gyroscope, geomagnetic sensor
* @Parameter Store the address of all data
*/
void getAllData(struct bmx160SensorData *magn, struct bmx160SensorData *gyro, struct bmx160SensorData *accel);
/*
* @function Turn off geomagnetic sensor, gyroscope enters low power mode(there are data output from accelerometer)
*/
void setLowPower();
/*
* @function Turn on geomagnetic sensor, gyroscope enters normal mode
*/
void wakeUp();
