    Thanks for all the answers ..

    I measured the SCK frequency 333 khz at 64 mhz so I wish pbp had a modification parameter for it (since we can't use all the pins for hardware SPI purpose)
    Well , Maybe ART's suggestion may work .. as a subroutine .. Why not .. I'll try .. It shall be faster after all ..

    Thanks once more to both of you

    It’s doesn’t “might” work, I play MP3s by using hardware SPI to read from SD card, and the above routine to write to the MP3 decoder.
    Mind you, there are a few varieties of SPI you might have to experiment with (see the configuration of any pic with hardware SPI).
