Hi @Ahmad Danial Ahmad Sobri,

It seems you're having trouble with MATLAB recognizing a USB-connected DSP board.

Here's a concise guide to address the issue:

1. Check Drivers: Ensure the DSP board's drivers are properly installed on your system.
2. MATLAB Packages: Use `supportPackageInstaller` to add the necessary MATLAB support packages.
3. MATLAB Setup: Configure MATLAB's communication settings, such as the COM port for your DSP board.
4. Test the Connection: Try MATLAB's `serialport`, `read`, and `write` functions to verify connectivity.
5. Permissions: Make sure MATLAB has the required permissions to access USB ports.

For serial communication, you can use the serial or serialport function to create a serial port object. Here's an example:

% Replace 'COM3' with the actual COM port your DSP board is connected to.
s = serialport('COM3', 9600);
configureTerminator(s, 'LF'); % Or the appropriate terminator for your device
% Now you can read/write using the 'read' and 'write' functions.
