Hi,
I want to use lite_on ltm8522 serial 3 dig 7 seg display
(datasheet: http://rapidshare.tv/601510 ) which requires 36 bit data with clock.
Is it possible to send this kind of data using shiftout command in pbp ?
Thanks.

This is a example with RTC DS1302:

    RELRST = 1 ' Ready for transfer
    ' Write all 8 RTC registers in burst mode
    Shiftout RELIO, RELSCLK, LSBFIRST, [$be, rtcsec, rtcmin, rtchr, rtcdate, rtcmonth, rtcday, rtcyear, 0]
    RELRST = 0 ' Reset RTC
