Function Documentation

utl7segr_cfg_setup()

void utl7segr_cfg_setup

(

utl7segr_cfg_t *

cfg

)

UT-L 7-SEG R configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See utl7segr_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

utl7segr_default_cfg()

void utl7segr_default_cfg

(

utl7segr_t *

ctx

)

UT-L 7-SEG R default configuration function.

This function executes a default configuration of UT-L 7-SEG R click board.

Parameters

[in]

ctx

: Click context object. See utl7segr_t object definition for detailed explanation.

Returns

Nothing.

Note

This function can consist any necessary configuration or setting to put device into operating mode.

utl7segr_display_number()

err_t utl7segr_display_number	(	utl7segr_t *	ctx,
		uint8_t	number,
		uint8_t	dot_pos )

UT-L 7-SEG R display number function.

This function is used to show the number on the display.

Parameters

[in]	ctx	: Click context object. See utl7segr_t object definition for detailed explanation.
[in]	number	: Number from 0 to 99.
[in]	dot_pos	: Dot position (No use dot, dot left, dot right and dot left and right).

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

utl7segr_display_state()

void utl7segr_display_state	(	utl7segr_t *	ctx,
		uint8_t	state )

UT-L 7-SEG R display state function.

This function turns display on and off.

Parameters

[in]	ctx	: Click context object. See utl7segr_t object definition for detailed explanation.
[in]	state	: 0 ( UTL7SEGR_DISPLAY_OFF ) - Display off, 1 ( UTL7SEGR_DISPLAY_ON ) - Display on.

Returns

Nothing.

Note

None.

utl7segr_generic_write()

UT-L 7-SEG R data writing function.

This function writes a desired number of data bytes starting from the selected register by using SPI serial interface.

Parameters

[in]	ctx	: Click context object. See utl7segr_t object definition for detailed explanation.
[in]	data_in	: Data to be written.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.
