serial data to text format correction

Hello!,

I want to import some data to Matlab. I am sending a data package over serial and saving it into a text file. The data contains 3 values saparate by a coma and at the end of the line a '\n'. In total I send 24 ascii characters per line.

The correct format should look like this:

value1(float),value2(float)    ,value3(long)       '\n'
115.4,1.859 ,230974    
115.4,1.855 ,230975    
115.4,1.854 ,230976    

There are some spaces between value 2 and the coma and value 3 and the '\n'. These are empty char, leaving free characters for higher values since these variables increase in value over time.

From time to time I get an unwanted carrier return in the text file:

115.4,1.
859 ,230979    
115.4,1.857 ,230980    
115.4,1.862 ,230
981    
115.4,1.868 ,230982 

Is there a way to give the correct format to the data when this happens? Something like ignore the carrier [carriage (dpb)] return if happens in less than 23 characters. I have tried with textscan but I don't get the correct combination of parameters to do this.

thank you!

Are you writing the datastream or just trying to read it? The better solution would be to find some way to eliminate the source of the problem.

If you can't prevent transmission errors, about all you can do is read the file in a line-by-line fashion and parse each in turn, handling correctable transmission errors as you go. Not necessarily a trivial process.
