Re: Readback gain reduction of Dynamic Processor with ADAU1452
Hello Bernd and Miguel, SteveL came up with an ingenious way to produce a true exponential decay for a level meter. By applying feedback to a External Decay Peak Detector, he sets up the...
View ArticleRe: AD-FMCOMMS5 with KC705
There are no problems. The AD9361 part of the no-OS is independent of any carrier or FPGA (it is all through the SPI). At present, we don't have a reference design on KC705. If you have successfully...

Yes-- by programming the corresponding registers. Go through the user doc. and try to understand the design and the user controls.
View ArticleRe: Using no OS driver with custom h/w in verilog
I suggest you try a simple (such as the "hello word") EDK tutorial using Vivado (IPI) and SDK first.After the basic concepts are clear, you can take on FMCOMMS1.
