How can I simulate an ultrasonic sensor in combination with 4 MEMS microphones

An ultrasonic sensor is supposed to send sound waves to an object and the reflecting wave is supposed to receive the 4 MEMS microphones. The MEMS microphones should be classified in such a way that the constellation of microphones provides the best resolution.

Depending on the exact MEMS device, you will need to connect the MEMS to either an I2C or a digital input pin, of a device such as an Ardunino or Raspberry Pi.

In theory you could use a MATLAB function such as readDigitalPin to handle the reading of the sensor. In practice that interface is too slow, so you will need to create C / C++ code that runs on the Arduino or Raspberry Pi and handles the interface for you, and then relays the data to the MATLAB session. In practice you will need to buffer a number of samples from the microphones and transmit the buffer as a burst.

Depending on the sample rate you want to use, it might be a considerable struggle to get the data through an arduino serial to USB connection; you might need to switch to Raspberry Pi and use network (TCP or UDP) packets instead.

Thank you for your feedback. I actually want to simulate without Arduino or Raspberry Pi, just a virtual simulation. I don't know how to do that.
