5 Configuring the hardware

5.1 CAN (FD) interface

FRDM665CANFDEVB can be connected to a PC/laptop or other ECUs with power and

CAN cable. A 12 V supply line can be used to power the FRDM665CANFDEVB, female

sub-D9 connector can be interfaced to relevant CAN tool or ECU. SW2 can be used

to configure the CAN ID for MC33665A. CFG pins can also be configured to set the

arbitration speed for MC33665A. Press SW1 button (RST switch) after changing any

settings on SW2. Ensure the settings on J8 for VDD5V and J13 for VIO selection are

appropriate for power supplied to the board. CANFDEVB interface J10 can be used for

direct interface with S32K344EVB for CAN or CAN FD.
