Detailed Description

API for configuring and manipulating CO 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

co_cfg_setup()

void co_cfg_setup

(

co_cfg_t *

cfg

)

CO configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

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

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

co_init()

err_t co_init	(	co_t *	ctx,
		co_cfg_t *	cfg )

CO initialization function.

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

Parameters

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

Returns

• 0 - Success,
• -1 - Error.

See #err_t definition for detailed explanation.

Note

None.

co_read_an_pin_value()

err_t co_read_an_pin_value	(	co_t *	ctx,
		uint16_t *	data_out )

CO read AN pin value function.

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

Parameters

[in]	ctx	: Click context object. See co_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.

co_read_an_pin_voltage()

err_t co_read_an_pin_voltage	(	co_t *	ctx,
		float *	data_out )

CO 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 co_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).
