MMA7455 Class Reference

Acceleration range.

Definition at line 33 of file MMA7455.h.

Create an interface to the MMA7455 accelerometer.

Parameters:

sda	I2C data line pin
scl	I2C clock line pin

Definition at line 71 of file MMA7455.cpp.

Calibrate for 0g, that is, calculate offset to achieve 0g values when accelerometer is placed on flat surface.

Please make sure the accelerometer is placed on a flat surface before calling this function.

Returns:

true if request was successful; otherwise false

Definition at line 172 of file MMA7455.cpp.

Get calculated offset values.

Offsets will be calculated by the calibrate() method.

Use these values and put them in persistent storage to avoid having to calibrate the accelerometer after a reset/power cycle.

Parameters:

xOff	x offset is written to this argument
yOff	y offset is written to this argument
zOff	z offset is written to this argument

Returns:

true if request was successful; otherwise false

Definition at line 248 of file MMA7455.cpp.

Set calibration offset values.

These values should normally at one point in time have been retrieved by calling the getCalibrationOffsets method.

Parameters:

xOff	x offset
yOff	y offset
zOff	z offset

Returns:

true if request was successful; otherwise false
