frSetConfiguration

Valid for: CANoe DE

​
Function Syntax

frSetConfiguration( int channel, <configuration var> );

​
Description

This function writes the FlexRay protocol parameters from the configuration object to the FlexRay interface’s Communication Controller. The values must previously have been set in the configuration object in compliance with the FlexRay specification. The new protocol parameters will only be applied when the Communication Controller is reset!

​
Parameters

  • channel: FlexRay channel (cluster number)
  • <configuration var>: Name of the variable referenced by the configuration object. The variable name was defined when the object was created using frConfiguration.

​
Return Values

—

​
Example

The following CAPL program reconfigures the FlexRay Communication Controller with new FlexRay protocol parameters.

   frConfiguration gFRParams;
