(3) SRAM存储器 SRAM相当于计算机的内存,读写速度比Flash、EEPROM快N倍,掉电后数据丢失。 EEPROM: Arduino开发板上的微控制器带有EEPROM(Electrically Erasable Programmable Read - Only Memory,电可擦除可编程只读存储器)。存储于EEPROM中的信息不会因为Arduino断电而丢失。Arduino Uno 以及 Arduino Nano 开发板的 ...
闪光 Flash Memory也称为Flash ROM。在 Arduino 中,Flash 存储要运行的应用程序代码。在我们编写了一个 Arduino Sketch(例如 Blinky)后,我们只需单击 Arduino IDE 中的 Upload 按钮即可运行该 blinky 程序。 在后台,这将编译草图并生成一个二进制文件并将二进制文件存储到 Arduino 的 Flash 中。复位后,Arduino 将...
Flash memory is a type of electronically-erasable programmable read-only memory (EEPROM) that is commonly used to store data in electronic devices. Unlike traditional RAM, which loses its data when power is turned off, flash memory retains data even without power. This makes it ideal for applic...

EEPROM (Electrically Erasable Programmable Read-Only Memory),电可擦可编程只读存储器--一种掉电后数据不丢失的存储芯片。简而言之,如果希望保存内容,并且重新上电后读取上次保存的数据,推荐使用EEPROM,Arduino有EEPROM的接口函数可以使用。 ESP8266的EEPROM操作实际上是使用Flash模拟EEPROM,不过请放心,存在Flash中也是...
