I am trying to implement the following frame generation code in simulink. In summary the code does the following:
- Reads excel spreadsheet (which contains two columns, 1)time stap, 2)flight number)
- Starts a cycle, using the while statement, this is to mimic the passage of time
- Converts the two inputs into binary, concatenates them together and adds them to a frame (array)
- Every 10 cycles a new frame is created into which more inputs are add
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%555
clc;
%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
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
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The trouble that I am having with this is that I cannot simply copy and paste this code into a matlab function block in simulink.
The main problem at the moment is how to store multiple values in a frame in simulink, not just the latest input. Would implementing this using a Matlab System block in simulink work? If so how would I write it?
Hopefully this makes sense.
Thanks
