RNDIS is a proprietary Microsoft + * standard; this demo will only work on Windows 2000 (manually + * patched with the Microsoft RNDIS hotfix) and above (with no + * manual patches), or on the latest Linux kernels. + * + * Before running, you will need to install the INF file that + * is located in the RNDISEthernet project directory. This will + * enable Windows to use its inbuilt RNDIS drivers, negating the + * need for special Windows drivers for the device. To install, + * right-click the .INF file and choose the Install option. If + * Windows 2000 is used, the Microsoft INF file in the hotfix + * will need to be altered to use the VID/PID of the demo and + * then chosen instead of the LUFA RNDIS INF file when prompted. + * + * When enumerated, this demo will install as a new network + * adapter which ethernet packets can be sent to and received + * from. Running on top of the adapter is a very simple TCP/IP + * stack with a HTTP webserver and TELNET host which can be + * accessed through a web browser at IP address 10.0.0.2:80 or + * through a TELNET client at 10.0.0.2:25. This device also supports + * ping echos via the ICMP protocol. + * + * \note The TCP/IP stack in this demo has a number of limitations + * and should serve as an example only - it is not fully featured nor + * compliant to the TCP/IP specification. For complete projects, it is + * recommended that it be replaced with an external open source TCP/IP + * stack that is feature complete, such as the uIP stack. + * + * \section Sec_Options Project Options + * + * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. + * + * <table> + * <tr> + * <th><b>Define Name:</b></th> + * <th><b>Location:</b></th> + * <th><b>Description:</b></th> + * </tr> + * <tr> + * <td>CLIENT_IP_ADDRESS</td> + * <td>AppConfig.h</td> + * <td>Configures the IP address given to the client (PC) via the DHCP server.</td> + * </tr> + * <tr> + * <td>SERVER_IP_ADDRESS</td> + * <td>AppConfig.h</td> + * <td>Configures the IP address of the virtual server.</td> + * </tr> + * <tr> + * <td>ADAPTER_MAC_ADDRESS</td> + * <td>AppConfig.h</td> + * <td>Configures the MAC address of the RNDIS adapter on the host (PC) side.</td> + * </tr> + * <tr> + * <td>SERVER_MAC_ADDRESS</td> + * <td>AppConfig.h</td> + * <td>Configures the MAC address of the virtual server on the network.</td> + * </tr> + * <tr> + * <td>NO_DECODE_ETHERNET</td> + * <td>AppConfig.h</td> + * <td>When defined, received Ethernet headers will not be decoded and printed to the device serial port.</td> + * </tr> + * <tr> + * <td>NO_DECODE_ARP</td> + * <td>AppConfig.h</td> + * <td>When defined, received ARP headers will not be decoded and printed to the device serial port.</td> + * </tr> + * <tr> + * <td>NO_DECODE_IP</td> + * <td>AppConfig.h</td> + * <td>When defined, received IP headers will not be decoded and printed to the device serial port.</td> + * </tr> + * <tr> + * <td>NO_DECODE_ICMP</td> + * <td>AppConfig.h</td> + * <td>When defined, received ICMP headers will not be decoded and printed to the device serial port.</td> + * </tr> + * <tr> + * <td>NO_DECODE_TCP</td> + * <td>AppConfig.h</td> + * <td>When defined, received TCP headers will not be decoded and printed to the device serial port.</td> + * </tr> + * <tr> + * <td>NO_DECODE_UDP</td> + * <td>AppConfig.h</td> + * <td>When defined, received UDP headers will not be decoded and printed to the device serial port.</td> + * </tr> + * <tr> + * <td>NO_DECODE_DHCP</td> + * <td>AppConfig.h</td> + * <td>When defined, received DHCP headers will not be decoded and printed to the device serial port.</td> + * </tr> + * </table> + */ + diff --git a/lib/lufa/Demos/Device/ClassDriver/RNDISEthernet/asf.xml b/lib/lufa/Demos/Device/ClassDriver/RNDISEthernet/asf.xml new file mode 100644 index 0000000000..e871a8799e --- /dev/null +++ b/lib/lufa/Demos/Device/ClassDriver/RNDISEthernet/asf.xml @@ -0,0 +1,84 @@ +<asf xmlversion="1.0">
