Use the On-board EEPROM Read block to read nonvolatile data from the on–board Arduino electrically erasable programmable read–only memory (EEPROM).
EEPROM.write(word_address, 0x7F); } void loop() { } 将write()方法与字地址和要存储的值一起使用。地址必须是介于零和EEPROM.length() - 1之间的值,它告诉MCU在哪里存储值。 read()方法 以下示例从EEPROM中读取一个字节: #include void setup() ...
EEPROM Read(读取EEPROM) 在Arduino和genuino板上的微控制器有512字节的EEPROM存储器:当开发板关闭时(就像一个小型硬盘驱动器)开始记忆(即是保存这些数值)。 这个例子说明了如何通过EEPROM.read()函数读取所有字节,和怎样打印这些值到Arduino软件IDE的串口窗口上。
首先是read方法:read方法一次读取一个字节 #include <EEPROM.h> // start reading from the first byte (address 0) of the EEPROM int address = 0; byte value; void setup() { // initialize serial and wait for port to open: Serial.begin(9600); ...
1 EEPROM简介 EEPROM(Electrically Erasable Programmable Read-Only Memory)，叫做电可擦可编程可读寄存器。这是一种断电后数据不会丢失的存储设备，可以用来应对需要做记录做保存的场合。arduino已经为我们准备好了EEPROM类库”EEPROM.h”。https://www.arduino.cc/en/Reference/EEPROM 2 EEPROM库介绍 基于Arduino和Gen...
(long)EEPROM.read(address + 3); } void setup() { Serial.begin(9600); writeLongIntoEEPROM(100, 123456); long number = readLongFromEEPROM(100); Serial.print("Number: "); Serial.println(number); } void loop() {}For this example, we store the number 123456. Converted to bits: 00000000...
value = EEPROM.read(address); Serial.print(address); Serial.print("\t"); Serial.print(value, DEC); Serial.println(); // advance to the next address of the EEPROM address = address + 1; // there are only 512 bytes of EEPROM, from 0 to 511, so if we're ...
