I'm trying to filter data output of ADC SAR and send them vía bluetooth. I send data from ADC to filter vía DMA. At this moment, I'm sure that output data of ADC is correct because I tried it without filter and it works. I don't know if data doesn't arrive correctly to filter or if I'm not doing it correct with the filter.

I have tried it, now I have done the same in my project, but it doesn't work.

The problem is that the ISR never works.

I think I have this problem, but I don't know how to solve it in my case.DMA from filter output to an array using PSOC5
