GY80 All-in-one Library

Documentation

Copy Folder to Arduino/libraries

Include:

#include <GY80.h>

Create the GY80 class (here named sensor):

GY80 sensor = GY80();

For initialization call once:

sensor.begin();

To get values from all sensors:

GY80_scaled values = sensor.read_scaled;

See below for the GY80_scaled type.

Measuring functions:

GY80_scaled read_scaled();
returns scaled values from all sensors
GY80_single_scaled m_read_scaled();
returns scaled values from magnetometer in microTesla [µT]
GY80_single_scaled a_read_scaled();
returns scaled accelerometer values in G, 1G = 9.81 m/s2
GY80_single_scaled g_read_scaled();
returns scaled gyroscope values in dps, 6dps = 1rpm
float p_read_scaled();
returns pressure value in bar
float p_read_altitude();
returns altitude in m - not accurate, better used only for measuring
altitude differences and over a short time as air pressure changes 
with time
float t_read_scaled();
get temperature value in degree celsius

Measuring functions [raw values]:

GY80_raw read_raw();
returns raw values from all sensors
GY80_single_raw m_read_raw();
returns raw values from magnetometer
GY80_single_raw a_read_raw();
returns raw accelerometer values
GY80_single_raw g_read_raw();
returns raw gyroscope values 
uint32_t p_read_raw();
returns raw pressure value
uint16_t t_read_raw();
get raw temperature value
