Detailed Description

Function Documentation

pressure9_cfg_setup()

void pressure9_cfg_setup

(

pressure9_cfg_t *

cfg

)

Config Object Initialization function.

Parameters

cfg	Click configuration structure.

This function initializes click configuration structure to init state.

Note

All used pins will be set to unconnected state.

pressure9_configuration()

void pressure9_configuration	(	pressure9_t *	ctx,
		uint8_t	reg_adr,
		uint8_t	data_in )

Writing data to the configuration registers.

Parameters

ctx	Click object.
regAddr	Configuration register address
dataIn	Data that will be written in the register

Note

- Use this function when you want to write data to one of the configuration registers

• Configuration registers: PRESSURE_CONFIG, TEMPERATURE_CONFIG, MEASUREMENT_CONFIG and CONFIGURATION

pressure9_default_cfg()

void pressure9_default_cfg

(

pressure9_t *

ctx

)

Click Default Configuration function.

Parameters

ctx	Click object.

This function executes default configuration for Pressure9 click.

void pressure9_generic_read	(	pressure9_t *	ctx,
		uint8_t	reg,
		uint8_t *	data_buf,
		uint8_t	len )

Generic read function.

Parameters

ctx	Click object.
reg	Register address.
data_buf	Data buf to be written.
len	Number of the bytes in data buf.

This function reads data from the desired register.

pressure9_generic_write()

void pressure9_generic_write	(	pressure9_t *	ctx,
