We are using STM32F446 for MCU.

And we want to make a serial communication with stm32f4 and matlab.

Is it exchanged with MATLAB?

If it is, how can i load a data from stm32?

Thank you.

Hello Han,

Yes, you can establish serial communication between the STM32F446 microcontroller and MATLAB by following these steps:

Configure UART with the desired settings (baud rate, data bits, stop bits, parity).
Use firmware (e.g., HAL library) to send data via UART.
Connect STM32 TX to adapter RX, and RX to TX.
Open MATLAB and use the serialport function:

port = 'COMPort'; % Replace with your COM port

baudRate = Baudratevalue; % Baudrate

s = serialport(port, baudRate);

% Optional: Set terminator

configureTerminator(s, "LF");

% Read and display data

data = readline(s);

disp(data);

% Clean up

clear s;

I hope it helps.
