NAME
Device::Gyroscope::L3GD20 - I2C interface to Gyroscope on the L3GD20 using Device::SMBus
VERSION
version 0.010
ATTRIBUTES
I2CDeviceAddress
Contains the I2CDevice Address for the bus on which your gyroscope is connected. It would look like 0x6b. Default is 0x6b.
gyroscopeGain
Unless you are modifying gyroscope setup you must not change this. This contains the Gyroscope gain value which helps in converting the raw measurements from gyroscope register in to degrees per second.
xZero
This is the raw value for the X axis when the gyro is stationary. This is a part of gyro calibration to get more accurate values for rotation.
yZero
This is the raw value for the Y axis when the gyro is stationary. This is a part of gyro calibration to get more accurate values for rotation.
zZero
This is the raw value for the Z axis when the gyro is stationary. This is a part of gyro calibration to get more accurate values for rotation.
METHODS
enable
$self->enable()Initializes the device, Call this before you start using the device. This function sets up the appropriate default registers. The Device will not work properly unless you call this function
getRawReading
$self->getRawReading()Return raw readings from registers. Note that if xZero,yZero or zZero are set, this function returns the values adjusted from the values at default non rotating state of the gyroscope. Its recommended that you set these values to achieve accurate results from the gyroscope.
getReadingDegreesPerSecond
Return gyroscope readings in degrees per second
getReadingRadiansPerSecond
Return gyroscope readings in radians per second
calibrate
