What Are the Intel and Motorola Byte Orders in NI-CAN?Primary Software: Driver Software>>NI-CANPrimary Software Version: 2.4 Primary Software Fixed Version: N/A Secondary Software: Driver Software>>NI-VISA
Problem: I am setting up a CAN channel in the Measurement and Automation Explorer and the byte order options are Intel and Motorola. What are the endian byte orders for these? Solution: When setting up a CAN message in the Measurement and Automation Explorer the byte order options are Intel and Motorola, not big or little endian.
The Motorola byte order is Big Endian where the most significant byte is first. Shown in the image below is the number 1 in binary
The Intel byte order is Little Endian where the least significant bit comes first. When choosing Intel or Motorola for the byte order, you are actually choosing little or big endian.
