MATLAB: Help with matlab arduino question

arduino

I have a complete program on Arduino, I just want when I click a push button on a matlab gui that the program in Arduino will run, hope somebody can help me please…

It appears that it is possible. You need to take some steps to save the generated sketch before hand. Then you can have your GUI send the sketch to the device in order to start it running. See

I have not investigated arduino enough to know how to remotely control it to stop a sketch running afterwards.

Depending on your purposes, you might find it easier to instead have the sketch already loaded (e.g., use the tools to prepare and automatically upload it), but to have it programmed to wait for input before it proceeds with its main purpose.

MATLAB: How can i send the number plate data(e.g. GJ1XX1111) from MATALAB to arduino

Hi try this

Arduino code:

   #include <String.h>
   String str;
      void setup() {
        Serial.begin(9600);
      }
      void loop() {
        if(Serial.available() >0){
          str=Serial.readString();
          Serial.print("Received: ");
          Serial.println(str);
        }
      }

Matlab code (change to your COM port; Also the pause may need to be increased if a timeout occurs):

arduino = serial('COM3', 'Baudrate', 9600);
fopen(arduino);
pause(2)
str=('hello world');
fprintf(arduino,'%s\n',str);
recv = fscanf(arduino)
fclose(arduino);

you should receive the output "Received: hello world" in Matlab

MATLAB: Send SERIAL commands from MATLAB GUI to Arduino

I would delete the while.serial from arduino code and do it as:

void loop()
{
      if (Serial.available()>0)
       {
        my_data = Serial.read();
        ...
       }
] // end loop()

Since you open the serial port every time you want to send anything and close it again, it will take some time to perform the operation. Did you try to add a connect/disconnect button in your GUI to perform that operation so that the data is sent straight away once it is introduced by the user?
