 Network interface controller information type.

Functions

EMAC_BUFF_STATUS Lpc17xxEmacGetBufferStatus (EMAC_BUFF_IDX idx)
 Query buffer status.
void Lpc17xxEmacRxThread (void *arg)
int Lpc17xxEmacOutput (NUTDEVICE *dev, NETBUF *nb)
 Send Ethernet packet.

Variables

const uint8_t emac_clkdiv [] = { 4, 6, 8, 10, 14, 20, 28, 36, 40, 44, 48, 52, 56, 60, 64 }

Define Documentation

#define EMPRINTF (   args,
  ... 
)    printf(args,##__VA_ARGS__);
#define NUT_THREAD_NICRXSTACK   512

Referenced by Lpc17xxEmacInit().

#define EMAC_LINK_LOOPS   1000
#define NIC_PHY_ADDR   0

PHY address.

Any other than 0 seems to create problems with Atmel's evaluation kits.
