Function Documentation

pressure13_cfg_setup()

void pressure13_cfg_setup

(

pressure13_cfg_t *

cfg

)

Pressure 13 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See pressure13_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

pressure13_get_pressure()

err_t pressure13_get_pressure	(	pressure13_t *	ctx,
		float *	data_out )

Pressure 13 get pressure function.

This function reads voltage levels and converts them to proportional pressure in mBar.

Parameters

[in]	ctx	: Click context object. See pressure13_t object definition for detailed explanation.
[out]	data_out	: Output pressure.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

pressure13_init()

err_t pressure13_init	(	pressure13_t *	ctx,
		pressure13_cfg_t *	cfg )

Pressure 13 initialization function.

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

Parameters

[out]	ctx	: Click context object. See pressure13_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See pressure13_cfg_t object definition for detailed explanation.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

pressure13_read_an_pin_value()

err_t pressure13_read_an_pin_value	(	pressure13_t *	ctx,
		uint16_t *	data_out )

Pressure 13 read AN pin value function.

This function reads results of AD conversion of the AN pin.

Parameters

[in]	ctx	: Click context object. See pressure13_t object definition for detailed explanation.
[out]	data_out	: Output ADC result.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

pressure13_read_an_pin_voltage()

err_t pressure13_read_an_pin_voltage	(	pressure13_t *	ctx,
		float *	data_out )

Pressure 13 read AN pin voltage level function.

This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

Parameters

[in]	ctx	: Click context object. See pressure13_t object definition for detailed explanation.
[out]	data_out	: Output voltage level of the analog pin [V].

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

The conversion to voltage depends on the entered configuration of the ADC (resolution, reference voltage).
