i established serial communication between arduino and matlab.arduino rotates the motor ad prints "1" in the serial monitor.the serial data needs to be read by matlab and camera is triggered by matlab to capture an image.i want to control pointgrey camera using matalb?but this is not happening.
arduino code is working, but the matlab code is not working.
help required with image acquisition.pls
thanks.
%this is arduino code%
#include<Stepper.h>
int ms1 = 10;
int ms2 = 9;
int ms3 = 8;
int stepin = 6;
int dirnpin = 7;
int steps[8] = {10,12,14,16,30,40,60,100};
int k;
int numberofsteps;
boolean condition = true;
void setup()
{
pinMode(ms1,OUTPUT);
pinMode(ms2,OUTPUT);
pinMode(ms3,OUTPUT);
pinMode(stepin,OUTPUT);
pinMode(dirnpin,OUTPUT);
Serial.begin(9600);
}
void loop() {
digitalWrite(ms1,HIGH);
digitalWrite(ms2,HIGH);
digitalWrite(ms3,HIGH);
if (condition == true)
{ condition = false;
for(int k =0;k<8;)
{
barath(steps[k]);
delay(3000);
Serial.print(1);
k+=1;
}
}
}
int barath(int numberofsteps)
{
for(int j = 0;j<numberofsteps;j++)
{
digitalWrite(stepin,LOW);
digitalWrite(dirnpin,HIGH);
delay(5);
digitalWrite(stepin,HIGH);
digitalWrite(dirnpin,HIGH);
delay(5);
}
}
%matlab code%
arduino=serial('COM3','BaudRate',9600);
fopen(arduino);
TopCam = videoinput('pointgrey', '1');
start(TopCam);
for j = 1:10
commandforcamera = fscanf(arduino,'%i');
if commandforcamera < 10
TopImg = getsnapshot(TopCam);
imshow(TopImg);
end
end
stop(TopCam)
fclose(arduino)
