Function Documentation

int EmacOutput (  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.

int EmacInit (  NUTDEVICE *  dev  )

Initialize Ethernet hardware. Applications should do not directly call this function. It is automatically executed during during device registration by NutRegisterDevice(). Parameters: dev  Identifies the device to initialize.

Variable Documentation

NUTDEVICE devAt91Emac

Initial value: { 0, {'e', 't', 'h', '0', 0, 0, 0, 0, 0}, IFTYP_NET, 0, 0, &ifn_eth0, &dcb_eth0, EmacInit, 0, 0, 0, 0, 0, 0, 0 } Device information structure. A pointer to this structure must be passed to NutRegisterDevice() to bind this Ethernet device driver to the Nut/OS kernel. An application may then call NutNetIfConfig() with the name eth0 of this driver to initialize the network interface.

Initial value: { 0, {'e', 't', 'h', '0', 0, 0, 0, 0, 0}, IFTYP_NET, 0, 0, &ifn_eth0, &dcb_eth0, EmacInit, 0, 0, 0, 0, 0, 0, 0 } Device information structure. A pointer to this structure must be passed to NutRegisterDevice() to bind this Ethernet device driver to the Nut/OS kernel. An application may then call NutNetIfConfig() with the name eth0 of this driver to initialize the network interface.
