I have to create this array and the send each line to my arduino separetly
7 0 2 0 0 -1
8 6 3 9 0 -2
4 3 7 7 1 -3
4 4 6 7 7 -4
2 6 6 1 1 -5
4 9 3 5 2 -1
Matlab program
b = Bluetooth('HC-05', 1);
fopen(b);
x=[]; neg = 0;
for a=1:6
neg = neg - 1;
if (neg < -5)
neg = -1; %//wrap around
end
x = [x; [randi([0 9], 1, 5) neg]]; %//add new row of random numbers to x
fprintf(b,a);
disp(x);
end
disp('End');
disp(x);
The problem is that when I put fprintf function inside for it sends me only first line in correct form others all together. Output arduino
0 5 8 6 1 -1
03 54 89 61 18 --12
036 543 891 614 184 ---123
etc.
Disp in for function shows
7 0 2 0 0 -1
7 0 2 0 0 -1
8 6 3 9 0 -2
7 0 2 0 0 -1
8 6 3 9 0 -2
4 3 7 7 1 -3
Disp in the end show data in correct form.
End
7 0 2 0 0 -1
8 6 3 9 0 -2
4 3 7 7 1 -3
4 4 6 7 7 -4
2 6 6 1 1 -5
4 9 3 5 2 -1
So I think I got 2 options. Create array different way. Or in the end of the program split whole array and then send each line separetly. But I don't know how to do it. So can you guys help me I'm really desparete.
