#152277 - Save some trouble for yourself... Responding to: ???'s previous message |
You may want to search through this forum for some discussion of the reset circuit. You will find many threads on this subject here, some of them very long. You will also find discussion about the merit of using an R/C type reset circuit versus other possibilities. Some of these discussions you should read with interest but be aware that some of them contain a large amount of "reset religion".
To follow my preference I would suggest that you not even consider the R/C type reset circuit and instead use a suitable MCU supervisory chip or "reset generator" device. It will generally be to your benefit to do this even if it seems like it takes more PC board space than the extra resistor you came here to ask about. Michael Karas |
