안된다는 말이 있어서 따라가보니...

핀 자체가 실장이 안되어 있다고... (GPIO19)



bcm2835 has support for I2C slave. Refer to section 11 of http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf


Unfortunately, GPIO pin 19 (BSC slave CLK) was dropped. http://elinux.org/RPi_BCM2835_GPIOs


So, the built-in I2C slave cannot be used.
