Simple question that I have never seen a result for. Do they have an average number before the start failing.

I often wondr this as I load and reload my code trying to fix some stupid little thing.

So that is what help files are for. I must have been looking with my nose instead of my eyes. Thanks.

It appears I have no worries about the bs2 reaching its max number of 10 million. I am sure to fry it, drop, dunk it, or crash it before then.

True, 'aquasapien'. Note if you use the WRITE keyword in your program to write to the EEPROM, that will lower the lifetime of the location written to.

This is not usually a problem, but some people have been known to loop on a WRITE. If you do it once a millisecond (as the BS2 can do) you can wear it out in a matter of hours. So as long as you don't do that, you should be fine.

So, if you have a 'burn, test, oops, fix, recode, reburn, retest' cycle of 5 minutes or so, you can keep that up for years before wearing out the eeprom.
