XgNicDm9000e


Functions

 NicRxLanc (void *arg)
 NIC receiver thread.
int DmOutput (NUTDEVICE *dev, NETBUF *nb)
 Send Ethernet packet.
int DmInit (NUTDEVICE *dev)
 Initialize Ethernet hardware.

Variables

NUTDEVICE devDM9000E
 Device information structure.


Function Documentation

int DmInit NUTDEVICE dev  ) 
 

Initialize Ethernet hardware.

Resets the LAN91C111 Ethernet controller, initializes all required hardware registers and starts a background thread for incoming Ethernet traffic.

Applications should do not directly call this function. It is automatically executed during during device registration by NutRegisterDevice().

If the network configuration hasn't been set by the application before registering the specified device, this function will call NutNetLoadConfig() to get the MAC address.

Parameters:
dev Identifies the device to initialize.

int DmOutput 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.


Variable Documentation

NUTDEVICE devDM9000E
 

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.
