Processing data received via a COM port
显示 更早的评论
Hello, I have a microcontroller which outputs 3 values via a COM port. Each pair of values is spaced and separated by a new line from the others, for example:
10 11 21
92 23 12
34 44 22
etc.
How could I process this data in real time using the serialport function? I would like to continuously plot the x,y,z values in 3 subplots.
Thank you in advance!

First create the serialport object. Then configureTerminator . Then configureCallback with "mode" "terminator" . The configured callback should readline to get the values, then parse the values and do something appropriate with them.
If you are sure that the values are numeric (and nothing but numeric) then you can parse the line using sscanf . Or you can potentially
double(strsplit(LINE))
This relies on the fact that readline() returns a string scalar not a character vector.
