Function Documentation

rs232isolator2_cfg_setup()

void rs232isolator2_cfg_setup

(

rs232isolator2_cfg_t *

cfg

)

RS232 Isolator 2 configuration object setup function.

This function initializes click configuration structure to initial values.

Parameters

[out]

cfg

: Click configuration structure. See rs232isolator2_cfg_t object definition for detailed explanation.

Returns

Nothing.

Note

The all used pins will be set to unconnected state.

rs232isolator2_generic_read()

err_t rs232isolator2_generic_read	(	rs232isolator2_t *	ctx,
		char *	data_buf,
		uint16_t	max_len )

RS232 Isolator 2 data reading function.

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

Parameters

[in]	ctx	: Click context object. See rs232isolator2_t object definition for detailed explanation.
[out]	data_buf	: Output read data.
[in]	max_len	: Number of bytes to be read.

Returns

• >0 - Number of data bytes read,
• <=0 - Error/Empty Ring buffer.

See #err_t definition for detailed explanation.

Note

None.

rs232isolator2_generic_write()
