The microcontroller can store settings to EEPROM

to use the fuction set in configuration.h
#define USE_EEPROM_SETTINGS --> Save and recall Settings aktive
#define PRINT_EEPROM_SETTING --> Print settings to UART

Commands:
M500 - stores paramters in EEPROM
M501 - reads parameters from EEPROM
M502 - reverts to the default
M503 - Print Settings
