EEPROM Get: 从EEPROM获得一个值,并作为float格式串行打印。 EEPROM Iteration: 明白怎样到达EEPROM存储本地。 EEPROM Put: 用变量来把一些数值放到EEPROM里。 EEPROM Update: 保存从A0读取的数值到EEPROM里,仅在不同的时候写入,以延长EEPROM寿命。
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...
而**this实际是*(*this),也就是会调用EERef的*运算符uint8_t operator*() const { return eeprom_read_byte((uint8_t*) index ); }。 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...
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...
EEPROM.get( eeAddress, customVar );Serial.println( "Read custom object from EEPROM: " );Serial.println( customVar.field1 );Serial.println( customVar.field2 );Serial.println( customVar.name );}void loop(){ /* 空 */ }6）EEPROM Put：使用可变语义将值放入EEPROM 使用仅在数据与要写入的位置...
Arduino esp32是一款基于ESP32芯片的开发板,它具有丰富的功能和广泛的应用场景。结构EEPROM的存储数组是一种用于存储数据的数据结构。 结构EEPROM的存储数组是指在Arduino...
EEPROM Clear Sets all of the bytes of the EEPROM to 0. This example code is in the public domain. */ #include <EEPROM.h> void setup() { EEPROM.begin(512); // write a 0 to all 512 bytes of the EEPROM for (int i = 0; i < 512; i++) { EEPROM.write(i, 0); } // turn...
EEPROM.put(2,"12.67"); This writes the data to multiple locations -- something that would be easy to write yourself, but handy none the less. You will still need to keep track of how many locations this has written to, so you don't accidentally overwrite your data! You have to use...
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; ...
EEPROM.end() will also commit, and will release the RAM copy of EEPROM contents. EEPROM library uses one sector of flash located at 0x7b000 for storage. Three examples included. I2C (Wire library) Wire library currently supports master mode up to approximately 450KHz. Before using I2C, pins...
