    Dump external ADC data (SPI, USB, DMA, pulse generation)

    Thank you Paul. Unfortunately for me it's a work project :) I'll look into the Cypress chip - I should be able to add one to the FPGA hardware; I'll just have to give up on the idea to be able to verify my AD module before the FPGA hardware is completed. Not a biggie since it is a modular design...

    Dump external ADC data (SPI, USB, DMA, pulse generation)

    Thank you for a very thorough answer Paul, I really appreciate it! I did not think that the USB speed would be the limiting factor; I must have misread 12Mbit as 12Mbyte somewhere. :eek: I really do need to run the ADC at full speed for my tests though. There are of course USB<->SPI adapters...

    Dump external ADC data (SPI, USB, DMA, pulse generation)

    Hello! I am building an FPGA-based data measurement system which uses an AD7980 AD converter. I have just received the first prototype of the AD modules, but the FPGA part is not done yet. I want to test the ADC at Msa/s with as low jitter as possbile, and I was hoping that I could use an...
