ADC on spartan 3e

Hello;

I want to use the ADC on spartan 3e kit. I think I need to use SPI interface to connect the ADC to the FPGA. I wonder if I can find a VHDL source code for using ADC with SPI interface. Please help me...

Thanks...
 

Re: ADC on spartan 3e

thank you very much for your help

now I'm trying to find the maximum input voltage range of the ADC on spartan3E starter kit. According to the datasheet it seems 1.25v but this is a very small range I think Is there anyone know the range of the ADC?

Thanks

If your input is more than 1.25v you have to scale it.

Go through this reference design to learn more: **broken link removed**
 

thank you for the answers, Jack//ani

I am trying to implement a SPI interface to read ADC values but I couldn't be
succesful. I don't want to use picoblaze.

If anybody have VHDL code for the ADC - SPI interface, I will be very glad. please help me...

thanks...
 

ok i am doing the same job...
i am doing it via microblaze processor...
so u can get help if u like that
