Real-time data acquisition serial communication

The serial data acquisition is based on MATLAB. It can achieve real-time communication between the computer and the microcontroller. And we analyzed data in real time through MATLAB library functions. Finally, we used visual graphics window to display the results of the data analysis. This article described how to upload MATLB read by the microcontroller serial port to PC to the height of the ultrasonic data acquisition and real-time rendering height versus time. Connected through a computer and external acquisition, after the acquisition through the serial port or an external network to collect the sensor data to the computer, computer obtains the collected data, then mathematical modeling and theoretical study can be carried out based on mathematical model. So that one can reduce the difficulty of product development and shorten the development cycle.
