Function Documentation

adcInit()

void adcInit

(

Accelerometer *

acc

)

ADC initialization for the accelerometer.

Parameters

acc	pass a Accelerometer by reference

Returns

None

Parameters

acc	pass a Accelerometer by reference

Returns

None

read_axis()

int read_axis	(	Accelerometer *	acc,
		int	id
	)

Read axis for the accelerometer.

Parameters

acc	pass a Accelerometer by reference
id	adc channel raw data

Returns

int adc raw from the desire id

Note

0 X_AXIS, 1 Y_AXIS, 2 Z_AXIS, anything else will return 0

Parameters

acc	pass a Accelerometer by reference
id	adc channel raw data

Returns

int adc raw from the desire id

Note

0 X_AXIS, 1 Y_AXIS, 2 Z_AXIS, anything else will return 0

if 0: read x-axis elif 1: read y-axis elif 2: read z-axis else: 0
