How could I convert 12 bit parallel to OutputData for SHIFTOUT function?

Can I have a little example showing how to do that?

Thanks,

Lee

    The shiftout command will only handle bytes. If your variable is a word, you
    could shiftout variable.high byte, variable .lowbyte.

    Sure...

    SHIFTOUT Dpin, Cpin, Mode, [noparse][[/noparse]someData\12]

    This is covered in the manual (hint) and the help file (hint).

    Not so, Sid, SHIFTOUT can handle up to 16 bits. If you desire something
    other than 8 bits, then you must specify the bit count with the \
    parameter after the output data.

    SHIFTOUT Dpin, Cpin, Mode, [noparse][[/noparse]outputData\12]

    Thanks a lot for your help.

    Another issue, there are 36 clocks required to clock all the data,
    but my data is only 8 bit. What can i do?

    here is little sample code i wrote to generate 8 clock pulses while
    writing each bit, but i need some helps to generate 36 clock pulse

    DAC_CE CON 0
    DAC_DATA CON 1
    DAC_CLK CON 2

    wTemp VAR BYTE

    LOW DAC_CE
    wTemp = $100
    SHIFTOUT DAC_DATA,DAC_CLK,msbfirst,[noparse][[/noparse]wTemp]
    HIGH DAC_CE

    I appreciate for your helps,

    Lee

    Someone else was having trouble with that part back in January and I
    posted a fragment that I believe with work. Luckily, SHIFTOUT is very
    flexible and can deal with the needs of this device. I believe this
    will work for you (refer to the docs):

    LOW CE
    SHIFTOUT Dpin, Cpin, LSBFIRST, [noparse][[/noparse]1\1, segs0\8, segs1\8, segs2\8,
    segs3\8, an1\1, an2\1, 0\1]
    HIGH CE

    The docs don't make clear if the start bit is supposed to be a 1 or 0,
    so you may have to change the initial 1 in the output steam above to 0.
    Note that the \8 additions are not required (the function defaults to
    eight bits), I'm just doing it as good form to be absolutely clear. The
    variables called segs0 - segs3 will contain the bit patterns for your
    segments. You can use a LOOKUP table to convert a number into the
    proper segment bit pattern.
