专业饰品EEPROM读写

Question

(我正在使用Arduino IDE( 我试图实现的是，即使微控制器关闭，它也能保存"进度"。我已经尝试了一段时间来调整代码，但我还没有让它真正正确地保存/读取 EEPROM 的值，所以这是我代码的一部分(忽略其余部分以运行显示+我已经删除了所有不相关的代码(：

#include <EEPROM.h>

int happiness = 10000;
int y = 0;
int z = 0;
int sensorPin = A0;
int sensorPin2 = A1;
void setup() {
Serial.begin(9600);
EEPROM.write(5, 10000);
EEPROM.write(5, 10000);
hunger = EEPROM.read(8)- '0';
happiness = EEPROM.read(5)- '0';
display.begin(SSD1306_SWITCHCAPVCC, 0x3C);

int value2 = hunger;
EEPROM.write(5, happiness);

查看EEPROM.write的页面。 https://www.arduino.cc/en/Reference/EEPROMWrite

在那里，它说参数被定义为：

EEPROM.write(地址，值(

参数地址：要写入的位置，从 0 (int( 开始

值：要写入的值，从 0 到 255(字节(

现在看看您尝试写入EEPROM的数字：

EEPROM.write(5, 10000);

希望现在你能看到问题是什么。 你的第二个论点太大了。 您应该将其分成两个字节或使用不同的方法，例如EEPROM.put(查找(，该方法不会受到此限制。
