When using dscope I'm getting strange occurrences in the serial window My code is: #include <stdio.h> main() { char c; while ((c = _getkey()) !=0x1B){ printf ("key = %c\n",c); } } When the program is run, in the serial window, "key =" keeps repeating itself down the screen, even though no key has been pressed. As I am very new to this device it could be something very simple so any ideas would be grateful.
