Hi
I'm writing a custom block in python. The application goes like this:
I specify the minimum number of samples I need by using the forecast function. This ensures that I have that many samples available in the in-buffer of the block every time work is called. Once I have as many samples as I need, I slide a window over the samples. In each window slide I measure signal power. If power less than a pre-set threshold (I assume only noise is being received), do nothing. Keep sliding.
The moment power exceeds the threshold for the first time, I have to start measuring time. I need to see how many windows I'm able to slide in the next let's say, 10 milliseconds (because I expect that the actual signal transmission is to last for that long). As a hypothetical example, let's say by 7 milliseconds I've reached the end of the buffer. If my understanding is correct, once I reach the end, the next set of samples come in (as per forecast) and work is called again. My question is how do I make this next work call aware of this concept of time and that 3 milliseconds were unaccounted for in the last call?
Or is there a way to make sure that the in-buffer gets updated multiple times within the same work call?
Thanks
