    Are you implementing a software SPI connection.... There are loads of software SPI routines on the web... I have I2C but I haven't done SPI.... It would be easy enough to do..

    i'm gonna use MCU 8951(nxp) and max6952 that can drive the 5x7 led using spi
    i already done some searching about it and what i found is max6952 is serial. so that's mean i need to use spi to send the data to max6952.

    what i just understand is you need 4 pin to control the MAX6952, and that's pin is CLK, DIN, DOUT, and CS.
