#122309 - Thanks Erik - I'll give it a go Responding to: ???'s previous message |
I see a problem with this in my application, but it is worth a shot.
The issue I see is that it may be possible to have 2 "keys" active in a short space of time, so the first "key" triggers the interrupt. I then set it to look for no key so that I can see the release of the first key as you have suggested. However during that time the second key become active..... and I miss it, because I am currently waiting for the first key to be released before restoring the interrupt to it's "normal" look for keys state. There will be a sloution in their somewhere though, I have to think about it a bit more. Thanks for the clarification, I'll get back with what I find. Regards, Marshall |

an added comment | 01/01/70 00:00 | |
What is the rate of change on the input signals? | 01/01/70 00:00 | |
nothing of value except the ability to wake up the | 01/01/70 00:00 | |
Interrupt for pulse train | 01/01/70 00:00 | |
that's basically what the KBI does | 01/01/70 00:00 | |
Rate of change ~<100kHz | 01/01/70 00:00 | |
why not? | 01/01/70 00:00 | |
I did not discuss | 01/01/70 00:00 | |
It is ok but KBIF is set forever | 01/01/70 00:00 | |
that you do not clear the reason | 01/01/70 00:00 | |
I change the state of the pin before | 01/01/70 00:00 | |
