SPI Interface - need information on the slave system

SPI Interface

Hi,

I am new to interface protocols. And I am more of a analog/ mixed signal designer. I would really appreciate it if someone could help me out.

I have a design which i need to interface with an ADC having a SPI interface. According to SPI protocol, a master SPI can talk to a slave SPI.

So in order to talk to the ADC do i need to design a slave SPI. I don't know what is involved in designing a SPI or how it is done.

Could someone please let me know

Thanks

Surely the ADC is a SPI slave, so you have to design a master. How to do it depends on your hardware platform (e.g. programmable logic device, processor, discrete logic). Generally a shift register and a clock source is involved, also a counter for the required number of data bits respectively clock cycles. I assume, that you get sufficient information about the required waveforms from your ADC's data sheet.

Hi FvM,

For me my design is the slave and the ADC is the master..

can i realize the SPI with logic gates?

if yes.. could you please give me more detail on how it can be done...

thank you

Can you tell the ADC type?

Hi calculus_cuthbert..!

What is the design u r talking about ?
I mean what is the slave system like?
