5 Configuring the hardware
FRDM665CANFDEVB can be configured as stacked board to S32K344EVB.
5.1 CAN FD interface
FRDM665CANFDEVB can be connected to a PC/laptop or other ECUs with
power and CAN cable or connector. 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 (ID and CFG). Ensure the settings on J8 for VDD5V
and J13 for VIO selection are appropriate for power supplied to the board. CANEVB
interface J10 can be used for direct interface with S32K344EVB for CAN or CAN FD.
