Abstract

[en] When developing diagnostic interfaces for vehicles, the communication with the electronic control units occurs over K-lines or CAN buses. Moreover, since a higher bit rate is more and more required CAN with a flexible data rate, called CAN-FD, has been officially introduced in 2011.
On diagnostic interfaces the different communication protocols used, are in general implemented on microcontrollers or FPGAs. The main objectives of this thesis are to assess the performances of a specific microcontroller of the XMOS family and to assess the performances of a CAN and CAN-FD implementation on this microcontroller.
A test system has been mounted consisting of a VCI (Vehicle communication interface containing a CAN node), an evaluation board (XMOS general purpose sliceKit), a host computer and an oscilloscope (PicoScope 3423) which has been used to assess the frames measured on the CAN bus. Moreover, the timing deterministic characteristics of the XMOS microcontrollers have been used to measure the timing of the CAN and CAN-FD implementation to assess their feasibility and standard compliance.
As a conclusion, SPI and Ethernet have been implemented without any issue. However, it has not been possible to obtain a CAN-FD interface, because the timing requirements of the protocol are not met when working at a bit rate of 2 Mbps or above. Nevertheless, a fully functional CAN implementation has been obtained, CAN 2.0A and CAN 2.0B at 500kbps and 1Mbps.
