Detailed Description

API for configuring and manipulating LIN Hall 2 Click driver.

Any initialization code needed for MCU to function properly. Do not remove this line or clock might not be set correctly.

Function Documentation

linhal2_get_flux_density()

err_t linhal2_get_flux_density	(	linhall2_t *	ctx,
		float *	data_out )

LIN Hall 2 read flux density function.

This function reads magnetic flux density in mT.

Parameters

[in]	ctx	: Click context object. See linhall2_t object definition for detailed explanation.
[out]	data_out	: Magnetic flux density in mT.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

linhal2_set_en_pin()

void linhal2_set_en_pin	(	linhall2_t *	ctx,
		uint8_t	pin_state )

LIN Hall 2 set EN pin state function.

This function is used to set EN pin state of the LIN Hall 2 click board.

Parameters

[in]	ctx	: Click context object. See linhall2_t object definition for detailed explanation.
[in]	pin_state	: State of the EN pin state.

Returns

Nothing.

Note

None.

linhall2_cfg_setup()

void linhall2_cfg_setup

(

linhall2_cfg_t *

cfg

)

LIN Hall 2 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See linhall2_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

linhall2_init()

err_t linhall2_init	(	linhall2_t *	ctx,
		linhall2_cfg_t *	cfg )

LIN Hall 2 initialization function.

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

Parameters

[out]	ctx	: Click context object. See linhall2_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See linhall2_cfg_t object definition for detailed explanation.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

linhall2_read_an_pin_value()

err_t linhall2_read_an_pin_value	(	linhall2_t *	ctx,
		uint16_t *	data_out )

LIN Hall 2 read AN pin value function.

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

Parameters

[in]	ctx	: Click context object. See linhall2_t object definition for detailed explanation.
[out]	data_out	: Output ADC result.

Returns

• 0 - Success,
• -1 - Error. See #err_t definition for detailed explanation.

Note

None.

linhall2_read_an_pin_voltage()

err_t linhall2_read_an_pin_voltage	(	linhall2_t *	ctx,
		float *	data_out )

LIN Hall 2 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 linhall2_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).
