Hello everyone,
I wrote this code to communicate my device using MATLAB interface.
serConn = serial('COM11','BaudRate',9600); % Init. COM Port
fopen(serConn);
fprintf(serConn,' *ABCD*');
Rcvd = fread(serConn);
hexpass=sprintf('%02X ', Rcvd);
disp(hexpass);
fclose(serConn)
after compilation of this code i got following out....
24 12 32 45 00 90 09 08 .. .. .. ..
after running this code first time i got above mentioned output but if i run it 2nd time then it is showing me some garbage values like 1A 20 03 03 04 .. .. .. .. .. . But i want data will be same at both times. So please suggest how could i clear buffer values and how i will get same data all the time.
