BELOW is a part of my codes. ARDUNIO - MATLAB.
PROBLEM: I want to store all values of P, Q and V in every update of the loop so that it would now be easy for me to print it to excel using xlswrite.
CAN SOMEONE HELP ME WITH THIS. Or any alternative to store the data for DATA ACQUISITION FOR MY STUDY. your answers are a great help.
while strcmp(start,'DISCONNECT')
RxText = fscanf(serConn);
RxText = strtrim(RxText);
disp(RxText);
pause(0.5)
%%%%%%%for data acquisition
handles.counter = handles.counter + 1;
[InRange,power,va,var,pf,volt,current,id]=strread(RxText,'%s%s%s%s%s%s%s%s','delimiter',',');
%%%MAIN POWER ANALYZER
if strcmp(id,'B') %DATA FOR MAIN PA
set(handles.LP4,'String',power);
set(handles.LQ4,'String',var);
set(handles.LV4,'String',volt);
%%%%CONVERT STRING TO DOUBLE %%%%%%
P4= str2double(power);
Q4 = str2double(var);
V4 = str2double(volt);
%%%%CONDITION SET TO LOAD MAIN STAT
if P4>70 && P4<80
set(handles.STAT4,'String','WARNING');
elseif P4>80
set(handles.STAT4,'string','SYSTEM OVERLOAD');
else
set(handles.STAT4,'string','NORMAL');
end
%%%%%DATA ACQUISITION %%%%%
P4(handles.counter,1) = P4
%Q4(handles.counter,2) = Q4;
%V4(handles.counter,3) = V4;
% data = [P1 Q1 V1]
end

count = 0; %before loop
Inside the loop,
count = count + 1;
data(count, :) = [P1 Q1 V1];
