I am trying to do a filtering process on psoc5. I did lots of thing but with small issue I turn back the basic form of the project. I tried to solve problem myself but I couldn't understand the reason of the problem.
Here I am doing with ping pong dma and send datas to sd card with emfile. When I writing the datas to sdcard I am writing an array after that I am doing a shift operation (just for try to solve problem. I will use the results after.) Like this code.
FS_Write(pFile, (uint8*)filteredDataP0, (NO_OF_SAMPLES*2));
But in graph (you can see in attachments) , I wouldn't think to see shift operation results. But there are.
Firstly, I thought about the clear the isr flag, but it seems clearly that clear isr isn't needed.
Do you have any idea about the this problem.
