I'm doing a project where I need a really simple random number generator for the ATTiny 13. I would like to generate numbers between 0 to 255 and the sequence can repeat after generating 256 numbers.
As for the seed, I will store that in EEPROM and change it every time I apply power.... I know that limits me to 100,000 power cycles, but that should still work.
If the EEPROM exceeds it's lifespan, will it error on me or just return the same number every time? At that point, for this application it won't matter, as long as I don't hang the processor.
