How to continuously real-time plotting graph from arduino to matlab (10k Variable Resistor)

8 visualizaciones (últimos 30 días)
Hello and good day to all the experts and visitors of Mat-Lab, I am a mechatronic student and now facing problem trying to interface matlab and arduino..
I am trying to real-time plotting graph from arduino to matlab with (10k variable resistor), but the graph will stop plotting after reach the Maximun X-axis (I set 0-1000).
Can it continuously real-time plotting the graph non stop? full of appreciation or teaching me to solve it.
the code is shown below:
a = arduino('COM3');
interv = 1000;
passo = 1;
t=1;
x=0;
while(t<interv)
b=a.analogRead(0);
x=[x,b];
plot(x);
axis([0,interv,0,1024]);
grid
t=t+passo;
drawnow;
end

Hi,
just dont bound the axis, remove the bounds on the axis and that should allow it to continually plot the voltage.

You just have to change the axis when the highest value is reached:
axis([interv,2*interv,0,1024]); % adapt values to your needs

Very Thank you for replied
I set interv = 1000
after I change this code
the x-axis started from 1000 to 2000
how do I start from 0 - 1000 after the highest value is reached auto start from 1000 - 2000 , continuously non stop ?

just make use of while(1) after a = arduino and at the last make use of a end function this solves your problem

you need not set axis between 0to1024
instead give the following statement
axes auto;
by the way, thanks for your program... it was useful for me to learn!!

I am trying to plot current-voltage curve from Arduino to Matlab , can you help me to start ??

This did not work for me. I tried this one: Real Time Analog Voltage in Matlab using Arduino it uses line function. anybody knows how to scroll the time line?

try this code: clear all
a = arduino
x = 0;
for k = 1:1000
b = readVoltage(a, 'A0');
x = [x, b];
plot (x);
grid;
drawnow;
end
