Detailed Description

Function Documentation

rtd_cfg_setup()

void rtd_cfg_setup

(

rtd_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.

rtd_convert_temperature()

float rtd_convert_temperature	(	rtd_t *	ctx,
		uint16_t	input_data,
		uint16_t	referent_resistance )

Convert Temperature function.

Parameters

ctx	Click object.
input_data	Unconverted input data.
referent_resistance	Value of external referent resistance in Ohms.

This function convert data from temperature registers.

Note

Referent resistance on the click board can be changed to better match the sensor in use. Input the value of the resistor used in Ohms to get correct data.

rtd_init()

err_t rtd_init	(	rtd_t *	ctx,
		rtd_cfg_t *	cfg )

Initialization function.

Parameters

ctx	Click object.
cfg	Click configuration structure.

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

rtd_read_register()

uint8_t rtd_read_register	(	rtd_t *	ctx,
		uint8_t	reg_address )

Read from Register function.

Parameters

ctx	Click object.
reg_address	Address to read from.

This function reads data from the chosen register.

rtd_read_temperature()

uint16_t rtd_read_temperature

(

rtd_t *

ctx

)

Read Temperature function.

Parameters

ctx	Click object.

This function reads data from temperature registers.

rtd_write_register()

void rtd_write_register	(	rtd_t *	ctx,
		uint8_t	reg_address,
		uint8_t	write_data )

Write to Register function.

Parameters

ctx	Click object.
reg_address	Address to write to.
write_data	Data to write.

This function writes the input data into the chosen register.

Note

This function automaticaly adds write bit as needed by this device.
