Any help will be greatly appreciated. My goal is to receive a trigger on a Analog-In Channel to be followed by a Generated Signal on an Analog Out Channel after a specified time, and this needs to be repeated numerous times. How accurate can this specified time and how consistent can it be? Are there any built in functions that can get this accomplished. I have seen many references to the defined Wait functionality, which can accomplish this expected behavior, however the wait time varies and there is an approximate ~17ms delay. Thanks for your help.
In short, we rely heavily upon the Analog Discovery units in the lab and have grown to rely upon the scripting features that enable triggered signal averaging and custom signal processing. Is there a mechnism or plan to enable a similar set of features with the OpenScopeMZ. As a stand alone, simple scope the system works well but without the ablity to script its potential seems stunted. Ideas? Thoughts? Timeline?
Greetings, I am trying to build a very simple digital signal processing circuit into my FPGA, Basys 3 board. Below you can find a simple block diagram. As you can see the components are, - A clock converter - An ADC ( embedded xadc) - A digital filtering operation H(e^jw) ( simple addition, multiplication circuit) - An SPI bus for communicating with an external DAC I have managed to build the clock converter, and the filtering operation. However, I have failed over and over again at building SPI and ADC blocks. Especially the XADC block gave me ( and still gi
Hi, I recently purchased a Zybo board and used the DMA Audio Demo (https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-dma-audio-demo/start) to acquire audio input and output. The Audio codec records 5 seconds of audio and then passes it to the Zynq PL via I²S protocol, that is it transmits the bit clock BCLK, the word select RECLRC and the data recorded RECDAT. My goal is to take this data and apply a filter on it, before the stream is mapped into memory with a DMA and then sent back to the audio codec and played in earphones. But I don't really understand how th
