#184933 - That's the fundamental flaw with RC resets! Responding to: ???'s previous message |
Jan Waclawek said:
The weakness of RC reset is that it does not unconditionally provide a clean pulse. Absolutely! See: http://www.8052.com/faqs/119931 You can try to experiment with the values of R and C ... but there's no guarantee this will definitively help. That is the fundamental flaw with RC resets: you may find something that happens to "work" (sic) for most situations - but that will always leave some cases where it will fail... And, as Murphy's Law tells us, those cases will be the most inconvenient and frustrating possible! You might think you're saving a few pennies with a "cheap" (sic) RC reset - but the true cost can be far higher... |
