i mean that insted of using a NOR gate with 8 input, and then connect the output to the external int pin as well as connecting the inputs to a mcu port to know where there was a change, i was told that i can skip the using of the NOR gate by creating a timer int where every 10msec the mcu will check the port pins state.
the finding which pin changed is easy, so im asking about enabling the timer int i want. i did google it and it got me here :) |
