WriteByteArraySignalAsInteger

Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

  • dword WriteByteArraySignalAsInteger(signal aSignal, qword value, dword byteOrder, dword byteCutMode) // form 1
  • dword WriteByteArraySignalAsInteger(pdu aPDU, char signalName[], qword value, dword byteOrder, dword byteCutMode) // form 2

​
Description

Writes the value of a byte array signal, treating it as a 64-bit integer. Use this function if you previously wrote the value of a byte array signal with the .raw64 selector. This selector works only for integer signals, but byte array signals were treated incorrectly as integer signals in CANoe versions < 12.0 SP3.

​
Parameters

  • aSignal: A byte array signal
  • aPDU: An AUTOSAR PDU with a byte array signal
  • signalName: Name of the signal on the PDU
  • value: The to be written value.
  • byteOrder: Byte order for interpreting the signal bytes.
    • 0: little-endian (intel)
    • 1: big-endian (motorola)
    • See examples below.
  • byteCutMode: How the additional bits of the 64-bit value shall be cut if the signal has less than 64 bits.
    • 0: ignore bits at the end
    • 1: ignore bits at the beginning
    • See examples below.

​
Return Values

  • 0: No error
  • 1: The signal has more than 64 bits.
  • -2: The signal is not a byte array.
  • 3: Signal not found on the PDU (form 2).

​
Example

If a signal has 56 bits (7 bytes) and the value shall be written in motorola (big-endian) byte order and the given value is 0x9123456789ABCDEF, depending on the byteCutMode parameter, the following bytes will be set in the signal:
  • byteCutMode == 0: 91 23 45 67 89 AB CD
  • byteCutMode == 1: 23 45 67 89 AB CD EF
If the value shall be written in intel (little-endian) byte order, depending on the byteCutMode parameter, the following bytes will be set in the signal:
  • byteCutMode == 0: EF CD AB 89 67 45 23
  • byteCutMode == 1: CD AB 89 67 45 23 91
