Detailed Description

API for configuring and manipulating SPI Isolator 9 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

spiisolator9_cfg_setup()

void spiisolator9_cfg_setup

(

spiisolator9_cfg_t *

cfg

)

SPI Isolator 9 configuration object setup function.

This function initializes Click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See spiisolator9_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

spiisolator9_init()

err_t spiisolator9_init	(	spiisolator9_t *	ctx,
		spiisolator9_cfg_t *	cfg )

SPI Isolator 9 initialization function.

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

Parameters

[out]	ctx	: Click context object. See spiisolator9_t object definition for detailed explanation.
[in]	cfg	: Click configuration structure. See spiisolator9_cfg_t object definition for detailed explanation.

Returns

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

Note

None.

spiisolator9_read()

err_t spiisolator9_read	(	spiisolator9_t *	ctx,
		uint8_t *	data_out,
		uint8_t	len )

SPI Isolator 9 read function.

This function reads a desired number of data bytes by using SPI serial interface.

Parameters

[in]	ctx	: Click context object. See spiisolator9_t object definition for detailed explanation.
[out]	data_out	: Output read data.
[in]	len	: Number of bytes to be read.

Returns

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

Note

None.

spiisolator9_write()

err_t spiisolator9_write	(	spiisolator9_t *	ctx,
		uint8_t *	data_in,
		uint8_t	len )

SPI Isolator 9 write function.

This function writes a desired number of data bytes by using SPI serial interface.

Parameters

[in]	ctx	: Click context object. See spiisolator9_t object definition for detailed explanation.
[in]	data_in	: Data to be written.
[in]	len	: Number of bytes to be written.

Returns

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

Note

None.

spiisolator9_write_then_read()
