Thread Subject: check serial ports via matlab

Hello,

I would like to send data from a serial port to another serial port.
I would like to check this by sending data and check what i get through matlab.
How is this possible??

Thank you in advance
Jacob

Hi Jacob,

The basics are as follows:

s=serial('com1','BaudRate', 9600 );
inspect(s);
fopen(s);
if( s.BytesAvailable > 0 )
    data = fread( s, s.BytesAvailable );
end
fwrite(s,'Hello World!');
fclose(s);
delete(s);
clear s;

The following link provides documentation for using serial ports in MATLAB.
