#174443 - other ISR recommendation Responding to: ???'s previous message |
Joel Ward said:
I am simply asking the micro to set an ouput high, and poll (using a while loop) an input port pin until it returns low Another recommendation is to never put a loop in an ISR. I'd go with the timer interrupt as Erik suggested unless you need to wake up your mcu on a key press. |

| Why the extra hardware? | 01/01/70 00:00 | |
| wow | 01/01/70 00:00 | |
| other ISR recommendation | 01/01/70 00:00 | |
| or the other solution (my favorite) | 01/01/70 00:00 | |
| using timer | 01/01/70 00:00 | |
| Some switches have very long bounce time | 01/01/70 00:00 | |
| a lot depends on the switches themselves | 01/01/70 00:00 | |
| which is a $#@!! disaster | 01/01/70 00:00 | |
| Remember that there is more than push buttons out there | 01/01/70 00:00 | |
| What about the others? | 01/01/70 00:00 | |
| Majority of implementations synchronizes with key down | 01/01/70 00:00 | |
| Now I'm confused ... | 01/01/70 00:00 | |
