matlab script to resolve port handles using port names in matlab

To resolve port handles using port names in MATLAB, you can use the instrfind function to get a list of all available serial port objects. Then, you can check the port names of these objects to find the desired port handle.

Here's an example MATLAB script that demonstrates this:

main.m
% Specify the port name you want to resolve
portName = 'COM1';

% Get a list of all available serial port objects
portObjects = instrfind('Type', 'serial');

% Loop through each port object and find the one with the matching port name
for i = 1:numel(portObjects)
    if strcmp(portObjects(i).Port, portName)
        portHandle = portObjects(i);
        break;
    end
end

% Check if the port handle was found
if exist('portHandle', 'var')
    disp('Port handle found!');
    % Do something with the port handle ...
else
    disp('Port handle not found!');
end

In this script, we first specify the port name that we want to resolve, such as 'COM1'. Then, we use the instrfind function with the 'Type', 'serial' option to get all available serial port objects. We loop through each port object and compare its port name with the desired port name. Once we find a match, we save the corresponding port handle (serial port object) and break out of the loop.

Finally, we check if the port handle was found by checking if the variable portHandle exists. If it does, we display a message indicating that the port handle was found and you can proceed to use it for your communication needs. Otherwise, we display a message indicating that the port handle was not found.

Remember to replace 'COM1' with the actual port name you want to resolve.
