Question - Text in variables . . .

Hello,

Working with a BS2-IC using Basic Stamp 2.5 I understand that you
can store number etc. in variables (nib byte word). How can I store
a short sentance for display on a LCD later ?

Many thanks
Billy

    You don't really need to store it. Whenever you want the LCD to display
    something, just serout the info using LCD protocol.

    The easiest way to do that is to store the strings in EEPROM. There are
    several examples on our web site that show how to do this.

    I recommend you to bye the BS2p- version. This stamp has something
    very impotent if you're planning to store serial info. It's a
    scratch pad RAM, and can hold up to 126 bytes (letters). It's not
    Eeprom, so the info is cleared if power is removed. Still, the
    scratch pad RAM doesn't ware out after 100.000 writings like the
    Eeprom.

    Then I recommend you to store one char at the time in the Scratch
    Pad RAM. You can do a few calculations if the baud rate is less then
    4800, but it's better to store all the serial info first, then
    prose's it later.

    If you start with:
    '{$STAMP BS2p}
    '{$PBASIC 2.5}

    KeyIn VAR Byte `(0-255) input char
    Ix VAR Byte `(0-255) Counting scratch pad adr
    Ix2 Var Byte `(0-255)

    Ix=0

    MainLoop:
    SERIN 16,18447, 500, No_Data, [noparse][[/noparse]Keyin]`Port 16,1200 Baud, 500 ms wait
    Put ix,KeyIn ' Store in scratch pad RAM
    If KeyIn=128 Then Goto process_Data ` decimal value 128 could be
    the `end of transmission char'
    Goto MainLoop

    No_Data:
    ` Do something if nothing has arrived in 500ms.
    Goto MainLoop

    process_Data:
    For Ix2=0 to Ix
    Get ix2,KeyIn
    If Ix2>=??? Then LCDOUT ????? something
    Next
    Goto MainLoop

    You find better way of processing data on you're own, I guess.

    Stein.
