Hello,
I have an application that requires sending a signal from arduino to matlab GUI whenever a button being pressed on the arduino. The signal then trigger a camera on the matlab and start processing. Then by the end of process it sends back a signal from matlab GUI to arduino to trigger a LED. This process should be repeated everytime the button press. However the matlab gui need to be run everytime that i send signal from arduino to matlab. So how can I run the script everytime that press button?
Matlab code:
%Define 'Serial' as arduino port
Serial = serial('/dev/tty.wchusbserial1410');
% set the baudrate of the signal
set(Serial,'BaudRate',9600);
set(Serial,'Timeout',20);
%Open Serial Port
fopen(Serial);
pause (0.1);
data = char(fread(Serial,1,'schar'))
switch (data)
%Define 'Serial' as arduino port
Serial = serial('/dev/tty.wchusbserial1410');
% set the baudrate of the signal
set(Serial,'BaudRate',9600);
set(Serial,'Timeout',20);
%Open Serial Port
fopen(Serial);
pause (0.1);
data = char(fread(Serial,1,'schar'))
switch (data)
case '0'
set(handles.G,'Value',0,'Enable','On');
case '1'
% pause(2);
vid1 = videoinput('macvideo', 1,'YCbCr422_1280x720');
vid2 = videoinput('macvideo', 2, 'ARGB32_1280x960');
Rest of process .....
if num1+num2 >=1
fwrite (Serial, 1)
end
end
Arduino Code:
void skipped()
{
if (Serial.available ()>0)
{
matlabData=Serial.read();
if (matlabData == 1 )
digitalWrite (led3, HIGH);
}
}
