This shows how to use the EEPROM.put() method. Also, this sketch will pre-set the EEPROM data for the example sketch eeprom_get. Note, unlike the single byte version EEPROM.write(), the put method will use update semantics. As in a byte will only be written to the EEPROM if the da...
EEPROM.get(eeAddress, f); Serial.println(f, 3); //This may print 'ovf, nan' if the data inside the EEPROM is not a valid float. /*** As get also returns a reference to 'f', you can use it inline. E.g: Serial.print( EEPROM.get( eeAddress, f ) ); ***/ /*** Get ca...
最后去调用eeprom_read_byte((uint8_t*) index )实现读取。 另外*ptr++;实际是*ptr;ptr+=1; 二、put和write的区别 其实了解了get的原理,对应的put和write也是一样的了 ①write:单字节写入 write就是单字节写入:除了通过write外还有另一种方法写入:EEPROM[index] = 1;其实现原来跟write一样。贴个管方用例...

EEPROM.put(address,data);EEPROM.get(address,data); Multi variable EEPROM read/write The previous member functions are useful for writing single bytes or single struct objects to/from EEPROM but quite often want to switch between sets of data (or store more than just a single variable). ...
put(address,data) 更新任意数据或者对象 此函数替代write可以减少擦写次数,减少寿命 get(address,data) 读取任意类型的数据或者对象 实现多字节读取函数 #include<EEPROM.h> // 定义一个共用体,用于存储不同类型的数据 unionDataUnion{ intintValue; floatfloatValue; ...
This tutorial explains what is the Arduino EEPROM and what it is useful for. We’re also going to show you how to write and read from the EEPROM and build a project example to put the concepts learned into practice. We have a similar tutorial for the ESP32:ESP32 Flash Memory – Store...
