WIZnet芯片的LED状态
WIZnet的芯片能提供六种不同的网络状态。
这里有六种不同的LED灯：
<!--[if !supportLists]-->1) <!--[endif]-->LINKLED: Link LED / Active low in link state indicates a good status for 10/100M. It is always ON when the link is OK and it flashes while in a TX or RX state
<!--[if !supportLists]-->
2) <!--[endif]-->SPDLED: Link speed LED / Active low indicates the link speed is 100Mbps
<!--[if !supportLists]-->
3) <!--[endif]-->FDXLED: Full duplex LED / Active low indicates the status of full-duplex mode.
<!--[if !supportLists]-->
4) <!--[endif]-->COLLED: Collision LED / Active low indicates the presence of collision activity.
<!--[if !supportLists]-->
5) <!--[endif]-->RXLED: Receive activity LED / Active low indicates the presence of receiving activity.
<!--[if !supportLists]-->
6) <!--[endif]-->TXLED: Transmit Activity LED/ Active low indicates the presence of transmitting activity.
一般而言，这个黄色和绿色的发光二极管在RJ45里是被接驳到全双发光讯号和这个已连接的发光讯号。在接收和传送的时后，这个LINK指示灯会在闪。如果你想在传送中及接收中的发光二极管里分隔出这个LINK指示灯讯号，以下电路图应该要使用。
希望你喜欢^ ^ .
