Function Documentation

int accel_calibrate

(

void

)

Calibrate accelerometer.

Note device has to be leveled on a surface and not moving. Pre-condition:

• accel_init Post condition:
• None

Parameters:

Returns:

Zero on success. Negative value on failure.

int accel_init

(

void

)

Initialize accelerometer and setup for default operation sample at 100Hz, full resolution, no FIFO no interrupts.

This function configures the accel slave device via I2C.

Pre-conditions:

• initialized I2C interface

Post condtions:

Parameters:

Returns:

0 on success, -1 on fail

int accel_read

(

accel_data_t *

pData

)

Accelerometer axis read function.

This function reads values from the configured accel slave devices via I2C.

Pre-conditions:

• The accelerometer should be configured properly and in measurement mode.

Post condtions:

• Data is read into the buffer.

Parameters:

Parameters:

pData

struct of acceleration values as 16bit signed values

Returns:

0 on success, -1 on fail

void accel_registerWrite	(	unsigned char	regAddr,
		unsigned char	data
	)
