Hi Cristina,
I understand that you are looking for a way to reset the arduino board by using a GUI button in MATLAB. It is possible to do so using the Arduino support package for MATLAB.
To achieve the functionality of resetting an Arduino board programmatically from a MATLAB GUI, you would need to toggle one of the Arduino pins that is connected to the "Reset" pin. Although, this approach requires a physical connection between one of the Arduino's digital pins and its reset pin.
Here is an example function that will create a GUI button to resetting the Arduino:
function resetArduinoGUI()
% Create a simple GUI
fig = uifigure('Name', 'Arduino Reset', 'Position', [100, 100, 200, 100]);
btn = uibutton(fig, 'Position', [50, 35, 100, 30], 'Text', 'Reset Arduino');
% Specify the Arduino port and create an Arduino object
arduinoPort = 'COM3'; % Change 'COM3' to your Arduino's port
a = arduino(arduinoPort, 'Uno', 'Libraries', 'Servo');
btn.ButtonPushedFcn = @(btn,event) resetArduino(a);
end
function resetArduino(a)
% Pin connected to the Arduino's reset pin
resetPin = 'D10';
configurePin(a, resetPin, 'DigitalOutput');
% Toggle the pin to reset the Arduino
% Resetting is done by pulling the pin LOW, then back HIGH
writeDigitalPin(a, resetPin, 0);
pause(0.1); % Short delay
writeDigitalPin(a, resetPin, 1);
end
Note that, I am assuming that you are using Arduino Uno in this specific case.
This method should effectively reset your Arduino from a MATLAB GUI, mimicking the physical press of the reset button on the board.
Additionally, you can also look at the following references:
