there is false triggering when there shouldn't be any. So what have you done to identify the cause(s) of this "false" triggering? eg, if it's an external interrupt, have you looked at it with an oscilloscope? |

| Doesn't the '324 have an OC output? | 01/01/70 00:00 | |

| no oscilloscope :( | 01/01/70 00:00 | |
| then try 'selective grounding' | 01/01/70 00:00 | |
| This might be the reason | 01/01/70 00:00 | |
| Dangerous approach! | 01/01/70 00:00 | |
| Correct | 01/01/70 00:00 | |
| hysteresis? | 01/01/70 00:00 | |
| aka positive feedback | 01/01/70 00:00 | |
