hi nitish,
1) for info on adc16, go to the web site below, and click on adc16/250 : https://casper.ssl.berkeley.edu/wiki/Hardware 2) i don't know if anyone has made a yellow block for the adc16 for snap1, the same adc's are used on the snap1 board, so i think it's just a matter of changing the pin numbers from the roach2 adc16 yellow block. i suggest you consult a casper yellow block guru to see if that's all there is to it. 3) there are three different size fpga's you can request on the snap1 board when you order it, small (and cheap, medium, and large... to see if your design will fit on the small snap1 fpga, i suggest you put together a quick design and compile it to get a resource estimation. you only need to plunk down the large pieces of your design - it's doesn't have to be a working design or have the control parts of the design... best wishes, dan On Wed, Dec 26, 2018 at 9:35 PM Nitish Ragoomundun < nitish.ragoomun...@gmail.com> wrote: > Hello everyone, > > We have a tile of 24 antennas from which we need to acquire data.
