Decoding Cyton data format with Matlab code
Hi all,
I am trying decoding the 8-channel data format in a matlab function. I have implemented the following code (once I've opened the serial port), but I am getting no-sense value (looking at the acquisitions using the OBCI GUI):
*****************************************************
*****************************************************
data = fread(s,33,'uint8');
if data(1) == 160
n=1;
for i=3:3:24 %%3 bytes per canale [3,4,5], ..., [24,25,26]
byte1=double(typecast(uint8(data(i)),'int8'));
byte2=double(typecast(uint8(data(i+1)),'uint8'));
byte3=double(typecast(uint8(data(i+2)),'uint8'));
ch(n)=byte3*(2^16)+byte2*(2^8)+byte1;
n=n+1;
end
end
*****************************************************
Any suggestion is welcome, thanks in advance.

Anyway, I would like to know if that decoding with matlab code is ok or not.
