ESP8266 EEPROM:有关微控制器的所有信息

by Flo

带有 EEPROM 的 ESP8266 是一种用于永久存储的低成本微控制器。

了解ESP8266 EEPROM。

ESP8266是espressif公司推出的一款多功能32位微控制器,集成了无线局域网芯片。它允许设备轻松连接到互联网,并广泛应用于物联网(IoT)。

  • EEPROM 是一种非易失性存储器,即使设备关闭或重启,ESP8266 也能永久存储数据。
  • EEPROM 的存储容量为 4 KB。有办法增加或减少可用内存。
  • 可将 EEPROM 存储器划分为不同的扇区或块,以改善存储数据的管理。
  •  ESP8266的EEPROM可通过Arduino开发环境中的特殊功能和命令或使用C/C++等编程语言进行访问。
  • 与大多数 EEPROM 一样,ESP8266 EEPROM 的写入次数限制为 10,000 次。因此,建议限制对 EEPROM 的写入次数,以尽量减少对存储器的磨损。
  • 为了在 EEPROM 中存储文件并从其中读取文件,必须将 “EEPROM.h “库集成到主程序中。此外,还必须集成自己的数据结构。
  • ESP8266尤其适用于存储配置数据、设备参数、仪表读数或其他用户信息。

更多关于ESP8266 EEPROM的信息

自 ESP8266 发布以来,新的微控制器版本已经开发出来,例如 ESP32,它提供了更多的功能和更大的内存容量。

  •  ESP8266的EEPROM不支持内置纠错机制。因此,必须自行检查关键数据的完整性,必要时在软件中实施纠错。
  • 由于价格低廉、功能丰富,ESP8266 尤其受到开发人员和业余爱好者的青睐。
