this is correct ADC recoard code with Real time ?

Hello.

Thanks you for click.

now, i want RC servo result via ADC with real time.

i am not sure, this code record plot of ADC with real time. is it fine for real time. can i get advise ?

 clc; clear all; close all;                     %Reset all

 a=arduino('COM4','Due','Libraries','Servo');  

 ai_pin='A6';                                   

 s = servo(a, 'D7');

 tic;                 

 i=0;                                         

 while (toc<4)

    i=i+1;

    t(i)=toc;

    out(i)=readVoltage(a,ai_pin);    %Already voltages calculated

    figure(1)
    plot(t,out,'r');
    pause(0.05);

    if toc < 2
    in(i) = 0;
    writePosition(s, in(i));
    else
    in(i) = 0.5;
    writePosition(s, in(i)); 
    end
 end

MATLAB is not designed for real-time capturing of data. The toolbox is built on top of MATLAB and operates in a non real-time Microsoft Windows environment. Because of this, it is not possible to achieve deterministic real-time operation. What do you mean by saying real time?

Thanks you reply. in my case, realtime meaning "save data with real seconds". my misstake, sorry. yes.. to peoples, real time meaning real time is like kinda Vxworks.

i hoped save measured data from arduino board with real time(seconds).
