Function Documentation

int NicInit (  NUTDEVICE *    dev )

Initialize Ethernet hardware. Resets RTL8019AS Ethernet controller, initializes all required hardware registers and starts two additional threads, one for incoming and another for outgoing Ethernet traffic. This function takes more than 2 seconds to execute and should be called only once during system initialization. Applications typically do not use this function, but call NutNetIfConfig(). Parameters: dev  Identifies the device to initialize. The structure must be properly set.

int NicOutput (  NUTDEVICE *    dev, NETBUF *    nb )

Send Ethernet packet. Parameters: dev  Identifies the device to use. nb  Network buffer structure containing the packet to be sent. The structure must have been allocated by a previous call NutNetBufAlloc(). Returns: 0 on success, -1 in case of any errors.

THREAD (  NutMain   , arg    )

Main application routine. Nut/OS automatically calls this entry after initialization.
