Best EEPROM practices

(this article is a work in progress). My own advice will be added later...


Having a system that regularly writes parameters to the EEPROM can wear out the EEPROM, since it is only guaranteed to endure 100 k erase/write cycles. Writing the parameters to a circular buffer in EEPROM where each of the elements in the buffer can endure 100 k erase/write cycles can circumvent this. However, if the system is exposed to RESET conditions, such as power failures, the system needs to be able to identify the correct position in the circular buffer again. This document describes how to make safe high endurance parameter storage in EEPROM/

Here I publish articles related to my areas of interest, my brief notes that may save some time to others, as well as some of my works.

This site is a work in progress. I will add more sections in the future, such as
