I am currently looking for a uC for a project of mine which needs a CAN interface. This would be my first project using CAN. Since I want to send and receive messages between the master and at least 8 slaves I was wondering about the amount of CAN ports I need.
According to this post I can send and receive messages on the same uC using only one port.
Looking at the Part selector of Microchip one of the fields says 'CAN Receivers buffer' and 'CAN transmitters buffer', which suggests otherwise.
Can I use them on the same bus or do I need a busline for sending and a separate one for transmitting?
