A little help with shifting out Arrays?

[HenrikOlsson]

Hi guys,
I just did some tests here. Here's the testcode:

Leader VAR BYTE
myArray VAR BYTE[3]
Trailer VAR byte

Leader = 170
Trailer = 85

Test1:
  myArray[0] = 1
  myArray[1] = 127
  myArray[2] = 255
  PortB.5 = 0
  SHIFTOUT PortB.6, PortB.7, 1, [myArray\24]
  PortB.5 = 1

PauseUs 10

Test2:
  myArray[0] = 255
  myArray[1] = 127
  myArray[2] = 1
  PortB.5 = 0
  SHIFTOUT PortB.6, PortB.7, 1, [myArray\24]
  PortB.5 = 1

Pauseus 10

Test3:
  myArray[0] = 1
  myArray[1] = 127
  myArray[2] = 255

  PortB.5 = 0
  SHIFTOUT PortB.6, PortB.7, 1, [myArray[0], myArray[1], myArray[2]]
  PortB.5 = 1

Pause 100
END

The idea with the Leader and Trailer bytes was to see if the memory is alocated in the order it declared and if the shiftout would "fall into" those - turns out that's not the case in this example. Here are the captured results:

I was a bit surprised that both test 1 and test 2 gave the same results but it did.
