An example of how to save various data types by using esp32 EEPROM library functions under Arduino framework

Arduino Within the framework of ESP32 EEPROM The library function saves examples of various data types

---

be based on ESP32 The core library of firmware , That is, when calling, it will EEPROM.h The header file is referenced , You can use , There is no need to download the third-party extension library from the management library to realize .

EEPROM Introduction to library functions

In fact, the principle of this library implementation is based on the use nvs Byte array to simulate EEPROM For data storage ,EEPROM The essence is NVS Part of , Let's look at the operation in detail EEPROM The correlation function of ：

	uint8_t readByte(int address);
    int8_t readChar(
