Hello
I do have a Problem with windows bluescreens when using serial communication on 2 different COM Ports
I am on Matlab R2019a and Windows 10.
I use this code
function serialtest
f=instrfind;
if ~isempty(f)
fclose(f);
end
Terminator={'CR','CR/LF'};
SERIAL_MOTOR=serial('COM7','BaudRate',9600,'Terminator',Terminator);
SERIAL_MESSUNG=serial('COM6','BaudRate',9600,'Timeout',0.1);
Char_string='somestring';
fopen(SERIAL_MOTOR);
for i=1:1000
disp(i);
fprintf(SERIAL_MOTOR,"someotherstring");
SollV=fscanf(SERIAL_MOTOR,'%i');
if mod(i,100)==0
fopen(SERIAL_MESSUNG);
fprintf(SERIAL_MESSUNG,Char_string);
EmpfangenerString=fscanf(SERIAL_MESSUNG,'%c',10)
fclose(SERIAL_MESSUNG);
end
end
end
Sometimes the code triggers a Bluescreen on the fopen(SERIAL_MESSUNG).
But i can not reproduce it maybe 1 in 20 times of running this code the bluescreen occours. Does anybody have any clue wht could be the culprint of this error.
I already reinstalled Matlab, Windows 10 and all kind of drivers, including the newest driver from FTDI. I also had the Mainboard of my Notebook changed.
My only guess is, that the driver from FTDI is not very up to date, because it was last updatet 2017.
Any help is appriciated
