Analogue Input To Nexys 4


Go to solution Solved by JColvin,

Question

Hello!

 

I possess an PmodAD1 converter device. Already acquainted with the PmodAD1 and AD7476A data sheets, I have a question about the practical application:

 

Given an analogue input signal, what is the most optimal-or the most simple yet working-way to provide the CS and Clk signals for the AD1 PMOD? Is that assumed that CS and Clk are generated by the FPGA board?

 

Thank you,

 

Your customer.

Hi advisor,

 

Yes, both the CS and the Clk signal lines for the SPI interface will need to be generated by the FPGA board (the "master" board in terms of the SPI protocol).  I am not familiar with FPGAs so I can't tell you what the most optimal/simple way of providing these signals might be, but referring back to your question about the PmodDA4, I imagine you can generate those signals in the same way here.

 

Let me know if you have any more questions.

 

Thanks,

JColvin
