Generic read function.

Parameters

ctx	Click object.
data_out	Output data buf
len	Number of bytes to be read

Returns

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

This function reads a desired number of data bytes from I2C bus.

i2cisolator2_set_slave_address()

err_t i2cisolator2_set_slave_address	(	i2cisolator2_t *	ctx,
		uint8_t	slave_addr )

Set slave address function.

Parameters

ctx	Click object.

		uint8_t *	data_in,
		uint16_t	len )

Generic write function.

Parameters

ctx	Click object.
data_in	Data buf to be written.
len	Number of bytes in data buf.

Returns

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

This function writes a desired data to I2C bus.

i2cisolator2_write_then_read()

err_t i2cisolator2_write_then_read	(	i2cisolator2_t *	ctx,
		uint8_t *	data_in,
