To simplify, I decided to use DFB channel A for single stage BPF, and channel B for Hilbert.
How to connect the output of A to the input of B?
Do I have to go through a VDAC/ADC pair?
Easiest and fastest would be DMA.
Second solution, but CPU-intensitive is read from A result and write into B.
um, newbie here. :)
ok, DMA, but how do I connect the output of A to the inut of B?
I opened one of the examples that has a filter and I'm using it as a starting point.
I see arrows pointing from the ADC to the DFB, and from the DFB to the DAC.
Also, can I make the schematic sheet larger or do I have to add pages?
Right click in page whitespace and pick "change template".
The DMA connection is made in code, the arrows are just an explaining drawing.
DMA is not easy to handle, there are some videos and appnotes you shuld search for.
