Detailed Description

Function Documentation

ozone2_cfg_setup()

void ozone2_cfg_setup

(

ozone2_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. Be sure that the ADC selection is properly selected.

ozone2_init()

err_t ozone2_init	(	ozone2_t *	ctx,
		ozone2_cfg_t *	cfg )

Initialization function.

Parameters

ctx	Click object.
cfg	Click configuration structure.

Returns

0 - Ok, (-1) - Error.

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

Note

The ADC selection should be set before call this function.

ozone2_read_measurement()

err_t ozone2_read_measurement	(	ozone2_t *	ctx,
		uint16_t *	data_out )

Measurement Read function.

Parameters

ctx	Click object.
data_out	Output measurement level [ppm].

Returns

0 - Ok, (-1) - Error.

@description This function reads the level of the measurement signal voltage and calculates this value to ppm in the range from 10 to 1000 ppm.

ozone2_read_signal_voltage()

err_t ozone2_read_signal_voltage	(	ozone2_t *	ctx,
		float *	data_out )

Measurement Voltage Read function.

Parameters

ctx	Click object.
data_out	Output voltage value [V].

Returns

0 - Ok, (-1) - Error.

@description This function reads the level of the output measurement voltage.
