March Madness - EEPROM Dump |
I am working on some other Arduino projects that use the EEPROM for storing settings. I found myself in a situation where I needed to see what was in the EEPROM so I wrote this little utility to dump the contents in hex and ASCII.
This is a dump of the EEPROM from my LCDSerial settings.
