Newbie needs help

Hi there,
this is going to sound pretty silly to experienced users, but I don't have a clue.

I have a BS2 logging temperature readings in its EEPROM (by the hundreds) and I wish to turn the results into graphs using Excell. How do I transfer the data stored·in EEPROM into an Excell-file?

Thanks!

Erik

    I think what most people are doing in this situation is using DEBUG or SEROUT to send the (formatted) data to a terminal window, then copying the output to a file that can be imported into Excel.

    Thanks Jon,

    but that doesn't seems to work. Maybe I'm doing something wrong, here's my 'read-data-out-and-put-it-on-screen' program. When I run this, I cannot choose the copy function.

    FOR adres=0 TO 425 STEP 4
    · READ adres,tC.HIGHBYTE
    · READ (adres+1),tC.LOWBYTE
    · DEBUG DEC (tC / 10), ".", DEC1 tC, DegSym, ClrRt, CR
    · READ (adres+2), rhTrue.HIGHBYTE
    · READ (adres+3), rhTrue.LOWBYTE
    · DEBUG DEC (rhTrue /10), ".", DEC1 rhTrue, "%", CR, CR

    Am I missing something here?shocked.gif

    In the Stamp editor Debug terminal window you can select the desired text, prest [noparse][[/noparse]Ctrl]+[noparse][[/noparse]C], then past ([noparse][[/noparse]Ctrl]-[noparse][[/noparse]V]) into a text program like Notepad -- then save the file. Or, you start Hyperterminal and capture it with that.

    With that much data, you will be better off with hyperterminal on the PC, or an equivalent terminal program. On the Mac, use zterm or goserial. Here are links that talk about how to set up hyperterminal (HTPE):
    www.seetron.com/ht_tip1.htm
    www.emesys.com/OWL2HTPE.txt

    For import to Excel, you are better off sending each record on a separate line, and the fields should be tab or space delimited without the unit symbols. After you capture that in HTPE, it can be opened in Excel easily and the data will fall into columns.

    Also, store your data in smallendian format (lower byte in lower address), so that you can use WORD modifiers to read out your data.

    DEBUG "degC",TAB,"%RH",CR   ' column headers for Excel
FOR adres=0 TO 425 STEP 4
  READ adres, Word tC, Word rhTrue  ' note Word makes program read easier
  DEBUG DEC (tC/10), ".", DEC1 tC, TAB
  DEBUG DEC (rhTrue/10), ".", DEC1 rhTrue,CR
NEXT

    Why not use stampdaq?

    Because I'm a newbie.

    What is stampdaq?

    StampDaq·is a program Parallax offers for free that does basically what your looking for, it is a plug-in for Exel that records up to ten channels and dumps the value in a spreadsheet.
