Save the important data in the form of key-value pairs to the NVS partition to prevent data loss after shutdown (to prevent program processing from being blocked, the data is actually written in 5 seconds later), please do not write the data to the NVS partition repeatedly, otherwise it will affect the flash life and cause damage
EEPROM write key value Create a key-value pair to save data to EEPROM.
EEPROM read key Read out the data content corresponding to the keyword.
EEPROM read key to int Read out the data content corresponding to the keyword and convert Str to the Int.
