@description This function reads data from the desired register.

Generic read function.

Parameters

ctx	Click object.
reg_addr	Register address.
data_buf	Output data buf
len	Number of the bytes to be read

@description This function reads data from the desired register.

pressure7_get_sensor_data()

void pressure7_get_sensor_data	(	pressure7_t *	ctx,
		float *	Temperature,
		float *	Pressure )

Read Pressure and Temperature data.

Parameters

ctx	Click object.
Temperature	Output Temperature data in C
Pressure	Output Pressure data in mBar

@description This function reads pressure and temperature data.

pressure7_init()

PRESSURE7_RETVAL pressure7_init	(	pressure7_t *	ctx,
		pressure7_cfg_t *	cfg )

Initialization function.

Parameters

ctx	Click object.
cfg	Click configuration structure.

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

pressure7_read_prom()

uint8_t pressure7_read_prom

(

pressure7_t *

ctx

)

Read calibration data from PROM.

Parameters

ctx	Click object.

Returns

CRC information: 0-ok, 1-error

@description This function must be performed at the beginning of the program in order to read the calibrated data from the PROM required to calculate the Pressure and Temperature measurement.

pressure7_reset()

void pressure7_reset

(

pressure7_t *

ctx

)

Start reset sequence.

Parameters

ctx	Click object.

@description This function starts reset sequence of click object ctx.

pressure7_send_command()

void pressure7_send_command	(	pressure7_t *	ctx,
		uint8_t	cmd )

Send command to click.

Parameters

ctx	Click object.
cmd	Action to be commited.

@description This function sends command cmd to click object ctx.

pressure7_set_over_sampling_ratio()

void pressure7_set_over_sampling_ratio	(	uint8_t	osr_d1,
		uint8_t	osr_d2 )

Set OSR(Over sampling ratio) for Pressure(D1) and Temperature(D2) data.

Parameters

ctx	Click object.
osr_d1	OSR for Pressure data
osr_d2	OSR for Temperature data

Note

OSR data (256,512,1024,2048,4095,8192)

@description This function sets OSR(Over sampling ratio) for Pressure(D1) and Temperature(D2) data.

pressure7_start_measurement()

void pressure7_start_measurement

(

pressure7_t *

ctx

)

Start measurement and calculation data.

Parameters

ctx	Click object.

Note

This function are called at the beginning of each measurement before the function returns the Temperature and Pressure values. This function reads digital pressure and temperature data, then calculates these values with values read from the PROM. Before calling this function, you need to set OSR (Over sampling ratio) for Pressure(D1) and Temperature(D2) data.

@description This function starts measurement and calculation data.
