Zitat:Beim Einlesen von Binärdateien muss man auf die Reihenfolge der Bytes achten. Es gibt das Big-Endian (Motorola) und das Little-Endian (Intel) Format. Ggf. muss man die Bytefolge beim Einlesen umtauschen. LabView arbeitet mit Big-Endian und Windows c- und c++ Programme in der Regel mit Little-Endian.
