How can I connect custom hardware to MATLAB or Simulink?

Hi.

I have a custom board with its own code and I want to use it as a controller in Simulink. How can I connect MATLAB or Simulink to my board and send and receive data from it?

It is not that easy. You will need to create a custom target. There is a step by step workflow for Cortex-A based processors and for Cortex-M based processors. General information can be found here.

If you download a hardware support package for for example Arduino, Raspberry Pi or Beagle board, you are basically downloading such a custom target which someone else has made for you.

thank you for your answer.

when I use the Arduino support package, I can't use my code on Arduino because Matlab(or Simulink) uploads its own code on Arduino. I don't want to change the code on Arduino I just want to send and receive data from it. is it possible?

Ah, that's different. What protocol do you want to use to communicate with it? I assume serial communication using USB connected to your PC? You should look into using Simulink Desktop Real-Time to communicate in real-time using serial port of your PC with Arduino.

Yes I have my board connected to USB. If I want to use the Simulink Desktop Real-Time, which block I should use? and how?

I have no experience with that, but you should google it because I think other people will have done it before.
