Thank you, Andrew!
And I have another question…
Please look at the picture, like
trigger[0] == 853325———28———16384
28 means this is the twenty-eighth times I call bbFetchRaw().
16384 means when the decimation is 64, the bufferLen is 16384.
So the trigger position is 2 * 853325 / 64 = 26,666.4062 ?
But 26,666 > 16384 ?
26,666 / 16384 = 1.63, so trigger position is at the middle of the
twenty-ninth buffer(when I call bbFetchRaw twenty-ninth times)?
