hi,all i have a problem in serial communication my code below:
Matrix1=[1 2 3 4 5 6 7 8 9 ];
s=serial('com3','baudrate',9600);
set(s,'flowcontrol','none');
set(s,'parity','none');
set(s,'databit',8);
set(s,'stopbit',1);
fopen(s)
for i=1:length(Matrix1)
A=Matrix1(i) ;
fwrite(s,A,'int8')
pause(2)
end
the problem with this code only the five value of matrix1 will be send via serial port to 8051 ,so when i display the received values only the first five values of matrix1 displayed.the other values of the matrix not send whats the problem,please help,suggest,idea
