Daiki Kato / DhcpServer_mbed-os

DhcpServer library for mbed-os.

Fork of DhcpServer by Daiki Kato

mbedボードをDHCPサーバとして使用するためのライブラリです。mbedボードとPCを直結する際などに使用してください。
このクラスは5つのIPアドレスを割り当てられることができます。
IPアドレスの上位3バイトはサーバーアドレスと同じで、下の1バイトは、10-14が割り当てられます。
例えば、サーバーアドレスが"192.168.0.1"の場合、IPアドレスは"192.168.0.10"～"192.168.0.14"が割り当てられます。

EthernetInterfaceでconnectを実行した後に、DhcpServerを使用してください。

    EthernetInterface eth;
    eth.init("192.168.0.1", "255.255.255.0", "192.168.0.1");
    eth.connect();
    DhcpServer dhcp_server(&eth, "HostName");
