#174446 - The real problem with debouncing Responding to: ???'s previous message |
In software anyway is it ties up timers and its rarely done properly and its a pain because you are dealling with asyncronous signals which is why i tend to use seperate hardware either the max single input or 8 input jobbies or my own debouncer if I am using a CPLD the code for which you will find in the code library. |

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 | |
