clock phase

[R_J]

Hi

I am using NI 8451 for SPI communication. I am using only basic functions. In 8451 SPI Config Property node, what is the meaning of clock phase and polarity.

Please explain it

Hello,

If you turn on the context help for these properties, you can see a description of what these properties do.  For the Clock Phase, this determines where relative to the clock edges that data is centered.  The Polarity configures the idle state of the clock.  These should be matched to the device with which you are trying to communicate.

Hope this helps!
