Difference between Full CAN and Basic CAN Mailbox - KBA86565
Last Updated: March 19, 2014
What is the difference between Basic CAN and Full CAN mailbox?
- A Full CAN communication can be easily set up with the help of a GUI with a very limited amount of programming involved, whereas Basic CAN requires all the parameters to be set in the firmware.
- Full CAN uses hardware for message filtering. Basic CAN requires the CPU to be interrupted every time a message is received to determine whether it should be accepted.
- Full CAN can be used only for receiving a single type of message per mailbox, whereas Basic CAN configuration can accept messages with a range of identifiers per mailbox.
- The random transaction rate (RTR) feature is available only for the mailbox that is set as Full CAN. Basic CAN does not have the RTR feature enabled.
