#87440 - clarification on the language Responding to: ???'s previous message |
so even though I have the input sitting high, I have to pull it low and then the Int does not fire until I realease the input.
what is "realease the input". Should read when the input is logic 1, and is pulled to logic 0 the interrupt does not fire until the input reverts back to logic 1. ie on the low to high transition rather than the, high to low transition as indicated in the documentation. BTW In New Zealand we can get all the parts we want, we may just have a longer lead time, and larger MOQs, however I like the atmel AT89c2051, it is a very vanilla version |
