Function Documentation

buttong_cfg_setup()

void buttong_cfg_setup

(

buttong_cfg_t *

cfg

)

Button G configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

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

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

buttong_get_button_state()

uint8_t buttong_get_button_state

(

buttong_t *

ctx

)

Button G get button state function.

This function reads the digital signal from the INT pin which tells us whether the button has been pressed or not.

Parameters

[out]

ctx

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

Returns

Function returns pin logical state (1 or 0).

See #err_t definition for detailed explanation.

Note

None.

buttong_init()

err_t buttong_init	(	buttong_t *	ctx,
		buttong_cfg_t *	cfg )

Button G initialization function.

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

Parameters

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

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

buttong_pwm_start()

err_t buttong_pwm_start

(

buttong_t *

ctx

)

This function starts the PWM moudle output.

Parameters

[out]

ctx

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

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

buttong_pwm_stop()

err_t buttong_pwm_stop

(

buttong_t *

ctx

)

Button G stop PWM module.

This function stops the PWM moudle output.

Parameters

[out]

ctx

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

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

buttong_set_duty_cycle()

err_t buttong_set_duty_cycle	(	buttong_t *	ctx,
		float	duty_cycle )

Button G sets PWM duty cycle.

This function sets the PWM duty cycle in percentages ( Range[ 0..1 ] ).

Parameters

[out]	ctx	: Click context object. See buttong_t object definition for detailed explanation.
[in]	duty_ratio	: PWM duty_ratio.

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.
