I am interfacing an led with via serial port. I have set up the serial port already.
I have a display with these specification parameters: baudrate:2400 data:8 bits end code:1bit
I am trying to display the test code which comes in the following format: "10"+"01H"+"0FFH"
I tried printf but didn't work: printf("10"+"0x01"+"0x0FF"); Any suggestions??

"Andy, is it possible to send u the protocol via email pls?"
If you want private consultancy on this, you'll have to pay for it.
Given that the protocol is not published, and has only been sent to you privately by email, are you sure that you are entitled to pass it on to any 3rd parties?
You might like to try getting something like this: www.hhdsoftware.com/.../serial-monitor-lite.html (many similar products are available - including free ones)
That will let you monitor exactly what the PC software is sending to the display. That should help you to understand the protocol...
You seem to have two problems here:
1. Learning the 'C' programming language;
2. Understanding the display protocol.
I suggest that you don't try to tackle them both at the same time - lay one aside until you've mastered the other.
