Hi all When i run the program below in the simulator the program works fine and the LED blinks correctly in the simulator window.But if I download the program to the phyCORE dev board the LED in the board blinks for 8 times with the delay in the program and after that it is glowing for ever and kick me is printed in the Serial window for ever. could anyone tell me why the program is not working correctly in the board? Looking for your replies... thanks
