    Why does SPI use periodic clock signals instead of manual HIGH/LOW?

    Hmm, could you give an example of using a hardware device? Also, I was talking about how in datasheets, they define certain times (ike in the picture above), not whether there are start/stop/don't care bits that needs to be send along.

    Why does SPI use periodic clock signals instead of manual HIGH/LOW?

    Ok. Here is my MATLAB code that basically follows standard SPI protocol. The device I am programming only requires 5 bits to specify its function. And here is an example of what I am asking. Basically, can the picture not look "nice"? I am asking because there's seems to be certain time...

    Why does SPI use periodic clock signals instead of manual HIGH/LOW?

    From my understanding of how SPI interface works, the clock basically sends out data when it is set to HIGH(or LOW). So, why does it seem like in pictures of the SPI lines, the setting of HIGH and LOW appears periodically. Can't we just put data onto DATA line, turn CLOCK line on to send, then...
