Hi,
I am working with nexys2 board
From the nexys2 board I am able to send 2 bytes of data to matlab
But the problem is that matlab is not able to receive the data
Can anyone please explain me where is the problem
Code:
nexys = serial('COM1', 'BaudRate', 9600, 'Parity', 'odd', 'Terminator', '', 'Timeout', 1);
fopen(nexys);
myNum = 4563;
%fprintf(nexys, 'd1539'); %Fungerar
%fprintf(nexys, 'd%4d', myNum); %Fungerar
for i=1:2
fprintf(nexys, 's');
scan_s1 = fscanf(nexys,'%s')-0;
fprintf(nexys, 't');
scan_s2 = fscanf(nexys,'%s')-0;
end
%scan_s1 = fscanf(nexys,'%s')-0;
%s1_dec = char2dec('s1'); %Fungerar inte
%'!'-0
%double('a':'z')
sensor1 = scan_s1*2;
sensor2 = scan_s2*2;
Thanks in advance
