Member Function Documentation

void getAccelero ( float * data )

Reads all accelero data, gives the acceleration in m/s2.

Function uses the last setup value of the full scale range, if you manually set in another range, this won't work.

Parameters:

data	- pointer to float array with length three: data[0] = X, data[1] = Y, data[2] = Z

Definition at line 123 of file MPU6050.cpp.

void getAcceleroRaw ( int * data )

Reads all accelero data.

Parameters:

data	- pointer to signed integer array with length three: data[0] = X, data[1] = Y, data[2] = Z

Definition at line 115 of file MPU6050.cpp.

int getAcceleroRawX ( void )

Reads the accelero x-axis.

Returns:: 16-bit signed integer x-axis accelero data

int getAcceleroRawY ( void )

Reads the accelero y-axis.

Returns:: 16-bit signed integer y-axis accelero data

Definition at line 99 of file MPU6050.cpp.

int getAcceleroRawZ ( void )

Reads the accelero z-axis.

Returns:: 16-bit signed integer z-axis accelero data

Definition at line 107 of file MPU6050.cpp.

void getGyro ( float * data )

Reads all gyro data, gives the gyro in rad/s.

Function uses the last setup value of the full scale range, if you manually set in another range, this won't work.

Parameters:

data	- pointer to float array with length three: data[0] = X, data[1] = Y, data[2] = Z

Definition at line 199 of file MPU6050.cpp.

Definition at line 29 of file MPU6050.cpp.

void read	(	char	adress,
		char *	data,
		int	length

length	- number of bytes to read
data	- pointer where the data needs to be written to

Definition at line 36 of file MPU6050.cpp.

void setAcceleroRange ( char range )

Sets the Accelero full-scale range.

Macros: MPU6050_ACCELERO_RANGE_2G - MPU6050_ACCELERO_RANGE_4G - MPU6050_ACCELERO_RANGE_8G - MPU6050_ACCELERO_RANGE_16G

Parameters:

range - The two bits that set the full-scale range (use the predefined macros)

Definition at line 80 of file MPU6050.cpp.

void setBW ( char BW )

Sets the bandwidth of the digital low-pass filter.

Macros: MPU6050_BW_256 - MPU6050_BW_188 - MPU6050_BW_98 - MPU6050_BW_42 - MPU6050_BW_20 - MPU6050_BW_10 - MPU6050_BW_5 Last number is the gyro's BW in Hz (accelero BW is virtually identical)

Parameters:

BW	- The three bits that set the bandwidth (use the predefined macros)

Definition at line 57 of file MPU6050.cpp.
