Detailed Description

Function Documentation

altitude4_cfg_setup()

void altitude4_cfg_setup

(

altitude4_cfg_t *

cfg

)

Config Object Initialization function.

Parameters

cfg	Click configuration structure.

@description This function initializes click configuration structure to init state.

Note

All used pins will be set to unconnected state.

altitude4_generic_read()

void altitude4_generic_read	(	altitude4_t *	ctx,
		uint8_t	reg,
		uint8_t *	r_buf,
		uint8_t	len )

Generic read function.

Parameters

ctx	Click object.
reg	Register address.
r_buf	Read buffer.
len	Read data size.

@description This function stores the len amount of data into the r_buf. The data is read from the address reg.

altitude4_generic_write()

void altitude4_generic_write	(	altitude4_t *	ctx,
		uint8_t	reg,
		uint8_t *	w_buf,
		uint8_t	len )

Generic write function.

Parameters

ctx	Click object.
reg	Register address.
w_buf	Write buffer.
len	Read data size.

@description This function writes the len amount of data from the w_buf to the address reg.

altitude4_init()

ALTITUDE4_RETVAL altitude4_init	(	altitude4_t *	ctx,
		altitude4_cfg_t *	cfg )

Initialization function.

Parameters

altitude4	Click object.
cfg	Click configuration structure.

@description This function initializes all necessary pins and peripherals used for this click.

altitude4_read_sensor()

uint8_t altitude4_read_sensor	(	altitude4_t *	ctx,
		altitude4_sensor_t *	sens_data )

Read sensor function.

Parameters

ctx	Click object.
sens_data	Sensor data object.

@description This function acquires sensor data from the click module and stores it in the sensor data object.
