CAN-CAN gateway in a MPC565 PowerPC microcontroller based
system
Requirement:
Design and development of CAN-CAN gateway in a MPC565 PowerPC microcontroller based
system.
System Overview:
In an in-vehicle network, a number of control units are interconnected using CAN. The
increasing numbers of electronic control units in modern vehicles are leading to excessive bus
loading in the system. This problem can be solved by subdividing a vehicle electronic system
into multiple CAN networks. A CAN-CAN gateway is used to interconnect these CAN networks.
Implementation:
Complete software solution for CAN, including drivers and error handling
The CAN messages and signals received on one network are sent onto the other CAN
network while observing filtering and conversion rules
Support of 11 bit and 29 bit identifiers
Used CAPL to automate the test cases
Automated test cases - Reusable and repeatable testing on a click of button
Testing and Validation:
Standard QA practices were followed to ensure quality of deliverables
Standard Testing practices including Unit testing, Function testing, System testing etc
Load testing on the CAN bus

Tools:
PowerPC controller based ECU
Trace32 debugger
Windows XP operating system with CANAlyser
PCMCIA cards- CANCardX and CANCardXL
