EEPROM.begin(size); 1. 写 将数据写入EEPROM,使用EEPROM.write();第一个参数为地址,第二个参数为保存的值。 EEPROM.write(address, value); 1. 读 从EEPROM上读取一个字节,使用EEPROM.read();参数为读取的地址。 EEPROM.read(address); 1. 更新生效 通过EEPROM.write()写入数据后,之后需要调用EEPROM.commit...
EEPROM的页写,EEPROM内部低位地址自动加1,高位地址还是由主器件程序发出。 低位地址正好对应页大小,如...

ESP32 - Preferences.h是一个用于在ESP32开发板上进行数据存储的库。它提供了一种简单的方式来读取和写入非易失性存储器(NVS)中的键值对数据。 ESP32 - Preferences.h的主要特点和优势包括: 简单易用:它提供了简洁的API,使得读写数据变得非常容易。
Preferences.h LibraryIn a previous tutorial, we recommended using the EEPROM library to save data on flash memory. However, the EEPROM library is deprecated in favor of the Preferences.h library. This library is “installed” automatically when you install the ESP32 boards in your Arduino IDE....
Hello, the functions of esp32 S3 EEPROM and preferences cannot be written normally, but the same program can work normally in esp32 The environment I tested was vscade platformio 1 1 reply maxgerhardt Jul 4, 2022 With what code and platformio.ini did you test that? liangwork168 Jul 4...
If you need to store permanent data that persists across resets you can use EEPROM, the Preferences library, or SPIFFS. See our tutorials: –https://randomnerdtutorials.com/esp32-flash-memory/ –https://randomnerdtutorials.com/esp32-save-data-permanently-preferences/ –https://randomnerdtutorial...
NVS总的来说,就是非易失性存储,类似MCU EEPROM,但实际上调用ESP32这些函数,数据是存储在FLASH中的。 它的管理方式类似数据库的表,在NVS里面可以存储很多个不同的表,每个表下面有不同的键值,每个键值可以存储8位, 16位,32位等等不同的数据类型,但不能是浮点数。NVS相关AP ...
