temperature sensor, here is what it looks like in VB:

type: 0 no. 0 value: 9
type: 0 no. 0 value: 0
...

(totally wrong values compared to what i saw with view button)

and under nqc, the datalog looks like this:

variable 23: 9
variable 23: 0


Variables are 'type' 0, but there's a disagreement between NQC and VB
about which var is in the log.  I haven't heard of any problems with NQC
in this respect, but I can test it out a bit and see.

But I wasn't logging variables... and I never have... I was logging sensor
values... and the values were certainly not things like 9, 0, 1, 3, ... (what
showed up for values) but were more like 16, 23, 32... (which show up 70 or so
values into the datalog, even after I take and re-take data)

It is as if my datalog never gets erased, but just added to, and now it
is a
huge mess.  I guess I should just stick to one programming environment at
a
time.

At the bytecode level, the datalog is cummulative.  It only gets erased
when you create the datalog.

But that doesn't seem to happen.

here is the program I wrote:

' Datalogging example

Option Explicit

Public Const SENSOR_1 = 0
Public Const SENSOR_3 = 2
Public Const LIGHT_TYPE = 3
Public Const TEMP_TYPE = 2
Public Const CON = 2
Public Const SENVAL = 9
Public Const TIMER = 1

Sub datalog()
    With UserForm1.Spirit1
        .InitComm
        .BeginOfTask 0
            .SetSensorType SENSOR_1, LIGHT_TYPE
            .SetSensorType SENSOR_3, TEMP_TYPE
            .SetDatalog 0
            .SetDatalog 600
            .Loop CON, 0
                .DatalogNext TIMER, 0
                .DatalogNext SENVAL, 0
                .DatalogNext SENVAL, 2
                .Wait CON, 500
            .EndLoop
        .EndOfTask
    End With
End Sub

and here is the program i am using to upload it:

Private Sub Uploadbutton_Click()

Dim arr As Variant
Dim I As Integer
Dim from As Integer
Dim datalength As Integer

Upload.databox.Clear

from = Val(Upload.from.Text)
datalength = Val(Upload.datalength.Text)

Upload.Spirit1.InitComm
arr = Upload.Spirit1.UploadDatalog(from, datalength)
If IsArray(arr) Then
For I = LBound(arr, 2) To UBound(arr, 2)
Upload.databox.AddItem "Type: " + Str(arr(0, I)) + " No. " + Str(arr(1, I))
+ " Value: " + Str(arr(2, I))

Next I

Else
    Beep
End If

End Sub

and the data that i get looks like this:

Type: 0 No. 23 Value: 9
Type: 0 No. 23 Value: 0
Type: 0 No. 23 Value: 1
Type: 0 No. 23 Value: 3
Type: 0 No. 23 Value: 128
Type: 0 No. 23 Value: 2
...

(certainly not light and temp data)

and then, if I use 70 or so as my "from" (starting point), then I can see the
data that somewhat resembles what I was actually measuring, in the VB or NQC
upload (the ROBOLAB upload for some reason only gives me the data back from a
ROBOLAB program that I had written to log light data, and it looks perfect
every time... as if there is a 'ROBOLAB' datalog and then an "everything else"
datalog)

So I guess the only real question that remains is why does my datalog not ever
get cleared???

  Re: VB Upload Problem
 
ok, so i'm getting a little closer to answering my own question, but i'm still stuck. if i write a new robolab program to take 10 points of light data and then upload it with VB, those 10 points get put into slots 10-20 in the datalog, and points (...)
