The MC9S12XS256 microcontroller does not have a dedicated I2C port, But can the SCI subsystem be used to communicate with I2c displays or similar accessories?
I2C can not communicate withSCI/LIN directly since they are different hardware pin defination.
You may need to use a gateway to transfer the protocol if I2C is must with MC9S12
Hi @fluffyflex,
It can only be emulated using GPIOs:
