Hi,
I want to interface on board ADC to spartan 3E startkit.
Actually I am developing digital filter in FPGA for that I need ADC
and DAC interface with Spartan 3E. I have done with DAC but now I want
to interface amplifier and ADC which are on board in Spartan 3E
starter kit .........If any one have it's VHDL or Verilog code please
give me..........Even I have find a document for implementing
amplifier and ADC usign picoblaze but I don't want it........So please
help me...............

Thank you,


Regards,
Krunal

Where do you have problems with the ADC? If you have already done the DAC,
the ADC should be very similar, because both chips on the Spartan3E starter
kit uses the SPI protocol and are from the same company.

For some code to output something on the DAC, see this VHDL code:

http://www.frank-buss.de/SignalGenerator/vhdl/spartan3e_test.vhd

The DAC parts needs about 30 lines. Reading the LTC1407 ADC and controlling
the LTC6912 amplifier is very similar. Maybe you can save some LUTs, if you
are using the Picoblaze.

Another interesting idea would be to implement some kind of very simple
microcode to define which bytes needs to be transfered to which SPI ports
and then using some BRAM (as ROM) to control it. But the Spartan 3E has
many free LUTs, so you can do it in pure VHDL (but use functions and
procedures to make the code less redundant).

This sounds like an assignment you've been given.

Shouldn't this work be your own?

Maybe you could tell us a bit more about this project of yours ?

We are'nt lazyy.....We have tried out all the ways of doing it but faced a lot of problems.If you have a solution,do help us.you have never seen us and trying to judge us.Dont be soo arrogant

Our project is to monitor industrial parameters using fpga and take possible corrective actions when these parameters go beyond their limits.So,we need to convert analog parameters to digital ones and that's the reason we need the interfacing code of adc with fpga.we tried all our ways,but could not do this.

Could you be so kind and name the ADC chip ? Brand ,model etc...

Best regards

Is this an SPI or I2C ADC?

If so there must be a number of working examples on the 'net.

Google is your friend.

Whenever I see a post involving a rather dated starter kit and an
element of desperation implying a deadline I think of student.

When they want the code delivered saving them any work that might look
like 'laziness' to those who read the post.

You've said in an earlier post "We tried all our ways, but could not do
this."

If you post the code you have written you will no longer be considered
lazy, until then....................... I won't be holding my breath!
