Hi All

 

I have always set the brownout voltage using the fuse setting.

 

I need to change this one some remote devices, is there any possibility this be set from my application?

 

Thanks

 

Thanks

Perhaps, if you explained the big picture of the project, a solution can be found, why would anyone need to change the brownout voltage level of the micro?

This is a classic XY problem, so tells us what your attempting to do, not what your attempted solution is....

Hi Jim

 

Some of my boards are set to 2.8V and all my new boards are set 2.4V.  I was trying to keep everything uniform.

 

 

Thanks

Thanks for the clarification, which AVR are we talking about, most classic AVR's only have one setting in the 2.xV range, one would not be able to choose between 2.4 and 2.8v?

Maybe the newer ones will let you set a specific level.

Is there anything to keep from setting all to 2.4V?  It's not a very precise voltage anyhow (which is more of an aside, since that implies any setting might be too sloppy).

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

Yes the devices that are set to 2.8V, are a distance from my location. I was hoping to set brownout in my firmware. 

Thanks
