I am thinking of a new product that uses two S12XE. One MCU will be a slave and read sensors. The main MCU would either request the information from the slave or receive it when is ready. I have done this in the past using SCI. I am looking at using CAN Bus to communicate. Do I still need CAN transceivers, or can I just connect the low level signals from the CAN pins.
I am open to ideas using some other method.
