??everything is same....only i am sending data (single character) from terminal window..
there is only pic with UART in it, and PC connected with USB module.
I have told full story now you are asking what was that..
everything is same....only i am sending data (single character) from terminal window..
there is only pic with UART in it, and PC connected with USB module.
at starting when i press any key in keyboard through terminal window it will send to PIC uC and code will test the pressed key and display only when if cond character is matched 'a' like this
