5.8.12 Pro II-FlexRay-2 Rev. E
The module Pro II-FlexRay-2 Rev. E is euqipped with 2 FlexRay interfaces,
each interface represents a complete FlexRay bus with 2 channels.
The module can be configured to start a FlexRay bus without any other bus
members. To do so, both FlexRay interfaces have to run as coldstarter nodes
and the interfaces have to be combined to a FlexRay bus via DIP switches.
You can also set the bus termination for each interface and channel via DIP
switch.
The description of the FlexRay module is divided into the following sections:
– Hardware
FlexRay Controller
The module Pro II-FlexRay-2 is equipped with two FlexRay controllers
MFR4310 from FreeScale
®
and runs according to the "FlexRay Communica-
tions System Protocol Specification V2.1". You program the interfaces with
ADbasic
instructions, which directly access the controller registers.
For configuration and status display of the FlexRay controllers you use the
appropriate registers. Here you can set all FlexRay parameters as e.g. bus
speed, bus timing, etc.
You find more information on the web site
in the fol-
lowing documentations from FreeScale
