支持楼主啊

分与秒的显示是乱的，是芯片问题还是初始化问题

flying03 发表于 2015-3-3 17:15:19

我用的这个芯片的模块，太诡异了，起初VCC接板子5V，显示乱跳，接收输入也偶尔不正解，换接板子上3.3V电源就正常了，资源上说宽电压2.5V-5.5V是骗人的？

HuaShine2015 发表于 2015-3-26 10:37:11

为什么要阉割掉github上原作者源代码里对32byte RAM读写功能呢？
32字节空间再加上Arduino本身的EEPROM可算是锦上添花效果了

darkscope 发表于 2015-4-9 15:04:20

时间正常在走，但是通过串口设置时间没效果啊，有人和我遇到一样的问题吗？

您好我测试ds1302也是这个问题 Saturday 2165-25-45 27:165:85一直显示这个时间请问您怎么解决的 ...

你的第一个问题解决：DS1302没有接上拉电阻，接好就可以了，第二个问题，是电源没的接好。

henhao ,very good

时钟模块显示的不是现在的时间是为什么啊

五哥U五哥 发表于 2015-4-23 11:57:18

为什么我的会出现这样的情况。。。3.3V就正常，VCC1和VCC2不管哪个节电池，另一个接5V都是这样

肿么编译不过去呢

哈哈......我做了个LCD时钟带温度显示、星期显示......
注意，三个库忘记贴上去了，补一下：

toopoo 发表于 2015-5-18 14:08:34

我今天尝试了一下，什么都正常，不过最后需要加个逗号，日期始终不对，输入18号，显示是10号

toopoo 发表于 2015-5-18 14:13:45

我去
接到3.3V一切正常了，这种小电流直接接板子的3.3V就OK了
