太长不看~~~~~~~~~ 哦，原来楼主还有这样的故事，佩服！
刚才编译一下，用MEGA2560,这段代码：“EEPROM.write(4,0); //地址4写零，表示没有任何文件，需要写头文件”
无法通过，看不懂什么意思。 本帖最后由 hi55234 于 2014-10-26 00:22 编辑

如果是编译错误详情可见这个，因为没装库

至于说效果，就是对EEPROM地址写值，没有返回值的，貌似
RE: GPS—arduino—蓝牙 测试1【完结】
本帖最后由 hi55234 于 2014-10-30 22:29 编辑1、连接图（使用端口）
2、EEPROM现行写入程序
太长不看，转1楼直接用
3、实际运行程序
太长不看，转1楼直接用
4、材料、成本
5、效果、其他
非常详细，感谢分享。 本帖最后由 hi55234 于 2014-11-6 22:24 编辑

楼主您好，能不能留一下qq，有几个比较急的问题想问您，
每当我烧写了【EEPROM写入】程序后，就无法向sd卡里面写入文件，屏幕上显示的sd卡状态右面也是空的，但是清空eeprom后，可以写文件，但是写入的都是纯数字，没有格式。
谢谢！
