SPI Example: (use with SPI wiring (https://adafru.it/aV6))

Initialization:

Before using the device object you constructed, you must initialize it with the sensitivity range you want to use:

bool begin(gyroRange_t rng);

where "rng" can be one of:

L3DS20_RANGE_250DPS - for 250 degrees-per-second range (default)

L3DS20_RANGE_500DPS - for 500 degrees-per-second range

L3DS20_RANGE_2000DPS - for 2000 degrees-per-second range

Example:

Sensing Rotation:

To sense rotation, you must first call the "read()" function to take a reading:

void read(void);

This function takes no parameters. After calling "read()". The raw x, y and z readings can be retrieved from the device

object's "data" member.

data.x - x-axis rotation rate in degrees-per-second

data.y - y-axis rotation rate in degrees-per-second

data.z - z-axis rotation rate in degrees-per-second

Example:

// Define the pins for SPI

#define GYRO_CS 4 // labeled CS

#define GYRO_DO 5 // labeled SA0

#define GYRO_DI 6 // labeled SDA

#define GYRO_CLK 7 // labeled SCL

Adafruit_L3GD20 gyro(GYRO_CS, GYRO_DO, GYRO_DI, GYRO_CLK);

void setup()

{

Serial.begin(9600);

// Try to initialise and warn if we couldn't detect the chip

if (!gyro.begin(gyro.L3DS20_RANGE_250DPS))

{

Serial.println("Oops ... unable to initialize the L3GD20. Check your wiring!");

while (1);

}
