At the present, when I transmit to the PC
it often do continuously. Consider the following points: 1. Does your input require debouncing? ie is it a mechanical switch, relay contact, slip ring etc... 2. Make sure that the input signal is sharp and clear of noise, you can add filter to it and shmitt trigger before it gets to the microcontroller. 3. Do you need your program to respond to rising edge or falling edge or both? 4. Michael Karas explained to you how to detect input change. Mahmood |
