Hi is there anyway of knowing if the LPC is receiving pulses on its INT0 pin. I have it already set up like this: IT0 = 1; //Pulses are edge detected EX0 = 1; //interrupt enable bit EA =1; It works fine, but is there anyway to find out if the pulses have stopped coming into this pin? The time the pulses will be present at this pin is unknown. This message is also posted at http://www.8052.com/forum/post.phtml
void Main(void) { P2 = 0x00; P0 = 0x00; init(); // configure ports brkrst_init(); //enable UART break detect Time_Base(); } What do you think happens after the call to Time_Base()? Stefan
