用Microduino CC3000搭建的WLAN天气系统
本帖最后由 wasdpkj 于 2013-11-23 20:09 编辑以Microduino Core+为核心，CC3000作为无线网关，获取Weather.com 上的天气数据，并且加以OLED显示
效果视频：

本次系统涉及成员一览：
搭建：
通电：
由于程序写得太傻，MEGA328的Core没法跑，所以用了MEGA644的Core+
库为了适配MEGA644做了一定更改，放在文末

现在好像没发现有microduino卖的
在量产了，12月开卖 ;P很酷的东西 老潘越做越大了哈，44这个做个字符串优化吧，我4过，比F()靠谱 幻生幻灭 发表于 2013-11-24 09:58 static/image/common/back.gif
老潘越做越大了哈，44这个做个字符串优化吧，我4过，比F()靠谱
哎呀 好东西，果断先收下了:lol 多谢 请问这种封装结构可以开源使用吧
我想移植到我的NXP板上 很厉害 赞一个~！ 恩 学习了 我看例子是做的短连接，可以做成长连接吗？
