Hi,
I am using the following command for serial communication
nexys = serial('COM1', 'BaudRate', 9600, 'Parity', 'odd', 'Terminator', '', 'Timeout', 1);
s = 's';
fwrite(nexys,s,'uchar');
scan_s1 = fread(nexys,1,'uint16');
t = 't';
fwrite(nexys,t,'uchar');
scan_s2 = fread(nexys,1,'uint16');
The data that is storing in scan_s1, scan_s2 is like:2048, 55040
I do not understand which format is this data
Actually I am sending 2 bytes of data from nexys2 board tp matlab
Can anybody help me in understanding this
Thanks Jim

2048 and 3042 and 55040 are quite valid 16 bit unsigned values.
If you want to see the bits composing the numbers, then use dec2bin(scan_s1, 16)
