pmw控制小灯加用在以太网控制板上就失效~求解
本帖最后由 天天煎蛋 于 2013-1-19 23:10 编辑我单独用uno就能pmw控制成功。但是把这段代码复制进去远程控制小灯（yeelink的例程）里面，pmw就失效了~~搞不明白
补充：我试了所有的口。都不行。
不管我程序里面定义的是什么口，1,2,3,4,5,6,7，8,9,12都不会亮。10，11，13都亮。

你是不是用的11口啊？11口已经被eth占用。选择别的pwm口吧 zcbzjx 发表于 2013-1-19 14:27 static/image/common/back.gif

我试了所有的口。都不行。

我也遇到过这个问题，我用的是w5100.发现10口无反应类似死机似的 11口调速不起作用，一直不知道什么原因，看了您的回答，我大概猜到原因了，那10口也是占用问题吗，大神？
