CAPLfunctionAfdxGetSignalBool

AfdxGetSignalBool

Valid for: CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE

Function Syntax

long AfdxGetSignalBool( long packet, char* signalName[] ); // form 1
long AfdxGetSignalBool( long packet, long offset, long bitPosition ); // form 2

Description

This function returns the value of a Boolean signal.

Note: A Boolean is represented by a single bit in a 32-bit field.

Parameters

• packet: Handle of the message.
• signalName: Name of the signal.
  Note: The signal and its message need to be defined in the assigned DBC file.
• offset: The offset value points to the starting byte of a 32-bit field in the AFDX payload area.
• bitPosition: Position [1..32] of a single bit in a 32-bit area pointed to by offset.

Return Values

• 0 or 1

• other value: See error codes.

Example

Analyze signals from an incoming AFDX packet using DBC information

on preStart
{
  AfdxRegisterReceiveCallback("OnPacket");
}

void OnPacket( long dir, long line, int64 timestamp, long bag, long afdxFlags, long packet )
{
  long lVal=0; // integer signal
  long eVal=0; // enumeration signal
  long bVal=0; // boolean signal
  double rVal = 0.0; // float signal
  char sVal[16]; // string signal
  byte oVal[16]; // opaque signal
  long len, status, err;
  long msgID;
  char msgName[256];

  // get message ID of this message
  msgID = AfdxGetMessageId( packet );

  // get message name of this message
  err = AfdxGetMessageName( packet, 256, msgName );

  // get signal status
  status = AfdxGetSignalStatus( packet, "VFG_OIL_TEMP_A_34" );

  // get integer signal
  lVal = AfdxGetSignalInt( packet, "VFG_OIL_TEMP_A_34" );

  // get float-signal 2
  rVal = AfdxGetSignalReal( packet, "VFG_OIL_TEMP_AB_32" );

  // get boolean signal 3
  bVal = AfdxGetSignalBool( packet, "VFG_OIL_TEMP_A_ON" );

  // get enumeration signal 4
  eVal = AfdxGetSignalInt( packet, "FLIGHT_GROUND_COND_3" );

  // get string signal 6
  len = AfdxGetSignalString( packet, "TEST_STRING14_CITY", 16, sVal );

  // get opaque signal 7
  len = AfdxGetSignalOpaque( packet, "TEST_OPAQUE14_IDENT", 16, oVal );
