ActiView example client raw data transformation
Posted: Sat Jul 24, 2021 5:59 pm
Hello, I am wondering about the example of the ActiView client in the Biosemi site where the data is first transormed like so:
256 is for the number of channels. To my understanding the powering of 256 is because the data is coming as words(= 3 bytes) according to the documentation, for reference this is said documentation in the code but I still am not grasping why.
I would really appreciate an explanation, even a very general one.
Best regards, Dor.
Code: Select all
normaldata = rawData(3,:)*(256^3) + rawData(2,:)*(256^2) + rawData(1,:)*256 + 0; Code: Select all
%input buffersize is 3 times the tcp block size %1 word = 3 bytes I would really appreciate an explanation, even a very general one.
Best regards, Dor.
