Hi all,
So I wrote some matlab code which works perfecting. I am now trying to add this code as a function block in simulink, however I am getting some errors. Mainly that the 'readtable' function does not work anymore! Anny suggestions??
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
CODE:
function y = fcn
%Initialisation of variables
x_count=1;
y_count=1;
frame=[];
t=readtable('Depart.csv');
A=table2array(t);
cycle_count=1;
start=610;
index=int64(A(x_count,1));
frame_index=1;
filename='Write_To.csv';
%this is the time cycle which runs from 6am to 11:30pm and increases by one
%minute every cycle. Starting at 601 to allign with cycle_count (which
%starts at 1 as well)
for time=601:2330
time;
cycle_count;
%The reason for using a while loop here is because multiple
%flights occure at the stame time.
while index<=time
%Table extraction (bit containting: time and flight no.)
x=de2bi(int64(A(x_count,1)), 24);
y=int64(A(x_count,2));
y_shift=bitshift(y,12);
d=de2bi(y_shift, 24);
final=x+d;
%adds the binary values of the x and y data to the frame
%sequencially
for i=1:length(final)
%adds single bit to the frame
frame(frame_index)=final(i);
frame_index=frame_index+1;
end
%Update variables
x_count=x_count+1;
index=int64(A(x_count,1));
end
%If the count has reached 10 we are going to reset the frame to
%be empty
if cycle_count==10
%Transmitt the frame, one element at a time
for u=1:length(frame)
y=frame(u);
end
time
disp('Printing frame at end of cycle');
frame
disp('Resetting cycle count');
frame=[];
frame_index=1;
end
if cycle_count==10
cycle_count=1;
else
cycle_count=cycle_count+1;
end
end
