Byte value to ASCII

Hello,

I'm working on a project to display a temperature value (with temp.
sensor DS1624) on a LCD (4-bit mode, hitachi compatible).

The problem I experienced is displaying the temperature value on the
LCD, because I don't know how to convert a binairy value to a string
value (a string value is needed to send to the LCD)

example:

value = %00010011 ( = 19)

howto convert %00010011 to characters "1" and "9" with a minimum of
code?


Thanks

    You can send this directly:
    For BS2:
    LcdBusOut = %0001
    PULSOUT E, 3 : PAUSE 5
    LcdBusOut = %0011
    PULSOUT E, 3
    For BS2p:
    LCDCMD E, %00010011 : PAUSE 5
    might want to look at the LCD Appmod code in AppNote #29121 for more
    details.

    Also, the Help for the PBasic command LCDCMD (BS2p) has very useful
    information even if you are programming to the BS2.

    Value VAR BYTE
    HiVal VAR BYTE
    LowVal VAR BYTE

    Value = %00010011
    HiVal = Value/10
    LowVal = Value - (HighVal * 10)
    ' At this point, HiVal = 1, LowVal = 9
    ' It depends onr you LCD character set
    ' what offset (if any) you need to add
    ' before you send each character to it.

    Look up the DIG operator in your HELP file or in your manual:

    value = 19 ' %00010011
    debug (value dig 1 + 48) ' ascii 49 = "1"
    debug (value dig 0 + 48) ' ascii 57 = "9"

    -- Tracy

    Thanks Tracy, I think the DIG operator will work. It saves me a lot
    of code!
