Scale Factor for Labstreaminglayer
Hi,
I'm a bit confused on the scale factor interpretation. When using the lab streaming layer, it says the data is being sent as a 32 bit float, but scale factor equation here assumes the stream is int32. How should I go about properly scaling the data in matlab to account for this?
On a similar note, how did someone arrive at using "scaleFactor = 4.5 / gain / (2^23 - 1); %converting to microvolts"? The data sheet says on page 38 the equation is "1 LSB = (2 × VREF / Gain) / 2^24 = +FS / 2^23" I feel like I'm missing something here. Should we adjust the scale factor based off the supply voltage? Or is there a voltage regulator on the board keeping the ADS1299's supply voltage at 4.5Vdc?
Thanks a ton!!
