I want to display the Matlab result which is in decimal format and getting generated continuously like:
Output=1, Output=2, .........
I used the Matlab Inbult functions for serial communication s=serial('COM7') fopen(s) fwrite(s,'output') but i am getting the output on LCD as "output"(in form like [o] [u]...[t]) not the one which i want (on LCD it should display 1,2,3,4,...)
How to do that??? Please help me out..
Thankx in advance Sumeet Saurav

fwrite(obj,A) writes the binary data A to the device connected to the serial port object, obj.
So when you invoke
fwrite(s,'output')
the code is writing out the string output rather than the numeric data of the variable Output.
I think that what you want to do instead is
fwrite(s,Output)
and/or specify the precision of the data as (for example)
fwrite(s,Output,'uint8')
