BO_ 500 IO_DEBUG: 4 IO
 SG_ IO_DEBUG_test_unsigned : 0|8@1+ (1,0) [0|0] "" DBG

说明：

  • The message name is IO_DEBUG and MID is 500 (decimal), and the length is 4 bytes (though we only need 1 for 8-bit signal)
  • The sender is IO
  • 0|8: The unsigned signal starts at bit position 0, and the size of this signal is 8
  • (1,0): The scale and offset (discussed later)
  • [0|0]: Min and Max is not defined (discussed later)
  • ””: There are no units (it could be, for instance “inches”)
  • @1+: Defines that the signal is little-endian, and unsigned: Never change this!
