Hi,
I'm using serial functions (fwrite, particularly), but it blocks the matlab sesion. My computer hasn't a built-in serial port, so I use a usb-serial converter. I think that the problem should be there. The same function (fwrite) works properly in a computer with a built-in serial port.
Another problem is the next:
s=serial('COM1');
fopen(s);
for i=1:8
fwrite(s,i,'int8','async'); %ERROR WHEN i=2.
end
Matlab notifies that an error occurs. The error is because there is a write operation in progress. A delay function solves the problem, but it also delays the total time involved in the transmission.
