Interaction between data collection and MATLAB [Copy link]

The content is relatively simple, that is, the ADC on the ufun board collects data, transmits it to the serial port interface of matlab through the serial port, and uses matlab to perform certain data processing.

Let's take a look at the matlab program first

The above is Matlab opening the serial port. The trouble is that the serial port number needs to be changed. If there is no such serial port, the program will report an error.

This section stores the data transmitted by the ufun serial port into a matrix, which is equivalent to the array in C.

Call the drawing function to draw, see the previous post for the effect.

This is the function of Matlab to receive serial port data, which can directly store multiple data.

In order to update the data, a while loop is used. After processing a set of data, the drawing is closed once. When another set of data appears, it is directly drawn together with the previous data to achieve a refresh effect.

In this way, we receive a group of data and process it, and integrate them to achieve continuous data processing, completing the data exchange between matlab and ufun.

The code refers to the Fulai example

Could you please share the Matlab code? It looks good.
