Pro trinket EEPROM读写
Pro trinket EEPROM read and write
(我正在使用 Arduino IDE)
我想要实现的目标是即使在微控制器关闭时也能保存 "progress"。我已经尝试了一段时间调整代码,但我还没有从 EEPROM 中正确地得到它实际的 save/read 值,所以这是我的代码的一部分(忽略 运行 显示的其余部分+我有删除了所有不相关的代码):

在此处查看 EEPROM.write 的页面。 https://www.arduino.cc/en/Reference/EEPROMWrite
那里说参数定义为:
EEPROM.write(address, value)
Parameters address: the location to write to, starting from 0 (int)
value: the value to write, from 0 to 255 (byte)
现在查看您要写入 EEPROM 的数字:
EEPROM.write(5, 10000);
希望您现在可以看出问题所在。你的第二个论点太大了。您应该将它分成两个字节或使用不受此限制的不同方法,例如 EEPROM.put(查找)。
