引脚改了后，又出来个问题，只显示一行信息了，该怎么解决？先谢谢了 wdb_9955 发表于 2014-4-11 10:16 static/image/common/back.gif

这种问题应该是有线没有接好，引脚悬空导致。 弘毅 发表于 2014-4-11 11:17 static/image/common/back.gif

我很仔细的检查了好几遍，接线不存在问题。可能还有其他问题吗？谢谢 wdb_9955 发表于 2014-4-11 11:43 static/image/common/back.gif

这种问题google搜索了下，貌似遇到的人都是gnd什么的接触不良导致。其他的就不知道了。 弘毅 发表于 2014-4-11 12:07 static/image/common/back.gif

原来是自己没有初始化，加条lcd.begin(16, 2)就可以了， 谢谢你。 弘毅 发表于 2014-4-11 12:07 static/image/common/back.gif

兄弟能在请教个问题吗？上面的程序只能把温度和湿度上传到yeelink, 我想把气压和光照全传上去，但不知道代码怎么写，上面写的代码也是网上抄来的，涉及到上传yeelink的代码看不明白，能帮我把上面的代码中关于着方面的代码后面加个注释吗？帮助我理解下。先谢谢了。 wdb_9955 发表于 2014-4-11 15:11 static/image/common/back.gif

没有呀，我现在是从一个个实例去理解一些东西，好幸苦呀 问下math.h在哪里能下载，谢谢！ zjbhm 发表于 2014-9-13 11:46 static/image/common/back.gif
问下math.h在哪里能下载，谢谢！
这个不用下载吧，安装程序里都用吧。我也是新手
