I'm working on an Arduino library that will maximize the life of the AVR's EEPROM. It takes the number of variables you want to store and does the rest. This is my attempt, which does not work in a...

Suppose there is a bug in a Java Card applet: a temporary byte array is stored in EEPROM instead of RAM. Moreover, suppose this byte array is overwritten with each APDU. This bug should damage the...

I have bought an I2C EEPROM. I want to store sensor and voltage data. I'm assuming that value can be bigger than one byte, and there can be a lot of data. Is it worth is such case to implement a fi...

The main issue I am addressing in the small embedded device redesign (PID controller) is the device parameters storage. The old solution I partially present here was space efficient, but clumsy to ...
