关于WII的鸡腿控接口
在视频网站上看到有人用WII的鸡腿控来控制小车或者舵机，感觉很酷，不知坛子里的那位大侠知道如何从鸡腿控里读取摇杆，按钮以及里面加速度计的接口，有没有库文件？{:soso_e100:} 这个东西你可以在谷歌里面搜索。关键是要找出它每个发出的信号所代表的意思。
现成的库文件貌似还没有，要不，你折腾一下，然后开源出来？

唉，我要是有这个本事就不是小白啦。昨天刚刚拆了一个鸡腿控，上面的引线上有标识，先送信号试试看吧 介个。。。你不需要拆呀。。。
你可以插上位机上面，然后直接读取它的信号呀。
我以前乱翻资料的时候记得，它的接口是IIC总线的接口。
但是电压是多少忘记了。
arduino 硬件直接支持iic。

是的，鸡腿控支持IIC的，俺不会上位机，直接拆了，晚上接出引脚，插面包板，看看会不会烧糊，等我消息呵呵。 电源不要接反就没事。。。。鸡腿很便宜，貌似国产的不到20 本帖最后由 三水 于 2012-2-28 14:00 编辑

:'( 我泪牛满面，就是要找这个啊，确实不用拆啊，我不仅拆了，还把摇柄的电位器给焊下来了，而且焊不回去了。买的国产鸡腿，19块一个，这是最便宜的买三轴加速度计的方式了，可是运费要十块！
感谢三水版主 :victory: http://www.ourdev.cn/bbs/bbs_content.jsp?bbs_sn=5174251&bbs_page_no=1&bbs_id=1025如果拆了可以参考下这个 这个我有，留个爪，明晚发 /*

万分感谢，我回去试一试. :handshake 呵呵。期待你把wii的控制信号给倒腾出来。
