CollectXYZData

Fc9-comp-macro.png CollectXYZData
Collect the data from the local XYZ buffers. The Axis parameter specifies the Axis to be read. 0 / 'x' / 'X' - X axis 1 / 'y' / 'Y' - Y axis 2 / 'z' / 'Z' - Z axis 
Fc9-u8-icon.png - BYTE Axis
Axis parameter 
Fc9-s16-icon.png - INT Return


Initialise

Fc9-comp-macro.png Initialise
Sets up up the communication bus and initialises the accelerometer module. Returns 0 for success and > 0 for fail.

Fc9-type-16-icon.png AD0 Pin
Determines the LSB of the I2C device address to allow up to two sensors to work together.

Fc9-type-7-icon.png Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
