Clock in spi and i2c

[Jinzpaul4u]

Hi there,

good wishes.

Do anybody have an idea about,what is the difference in the clock line of spi and i2c protocols ??


Thanks in Advance

No there is no difference in the clock.
do ask you question in detail. what exactly you're asking is not clear in you question.

I'm really sorry for the confusion,

In the initial state of i2c,both clock and data lines are in high impedance state or kept as high after data trasmission.Again it goes to idle state.

but i found a small difference in the spi clock.As far as i know, the initial stage clock become low state,correct me if i'm wrong.

so do anybody have an idea about,what is the difference in the clock line of spi and i2c protocols ??

The SPI clock can idle in the high state or the low state depending on the mode selected. Find a mode that matches the part you are interfacing to and check the documentation for the processor you are using on how to set the compatible mode.
