Preventing AVR’s EEPROM Corruption
I have been observing rhythm patterns being corrupted intermittently while I develop the firmware of the 909 clone. I first thought it is due to some bug in my firmware, but the occurrences are too random for it. I started thinking that it is some hardware problem in the processor, so looked this issue closely. I noticed that the corruptions happen only when I power cycle the processor. It’s a good clue. I searched around to know what this problem is and how to prevent it.
