I have a problem using an action function property in a serial connection with MATLAB. I want to connect the serial port of my computer to a device in interrupt mode (when my computer receives 10 bytes from the serial port, plot this data).

2018年12月11日 if(s.BytesAvailable) out = fscanf(s) end end. （或者str = fscanf(sr3) 读取数据）. 注意：当进入死循环后，用快捷键Ctrl+C强行中断. out = yang 123.

This velocity meter, on which I hope to write some more later on, works by two laser beams that are interrupted sequentially. By measuring the time in between the interruptions, the (average) velocity can be calculated, as the distance between the laser beams… Read More » I am trying to create a resistance measurer using an Arduino Uno and read out the data with MATLAB. For this, I wrote a programm in MATLAB, which sends a string over serial to the Arduino. LIBLIST is the same as LIBRARY_LIST_INFO.This only lists the library of a current running job.

ans = 17. Use fgets to read the data returned from the previous write operation, and include the terminator. settings = fgets(s) settings Label to associate with a serial port object, specified as a character vector or string. Tag uniquely identifies a serial port object.Tag is particularly useful when constructing programs that would otherwise need to define the serial port object as a global variable, or pass the object as an argument between callback routines. I am trying to create a resistance measurer using an Arduino Uno and read out the data with MATLAB.

You can also remove the else pause part. These changes should make the loop run fast enough to keep up with the serial data.

The property value is continuously updated as the input buffer is filled, and is set to 0 after the fopen function is issued. s.BytesAvailable ans = 13.
