Detailed Description
SLIP netif API.
Definition in file slipif.h.
Function Documentation
SLIP netif initialization.
Call the arch specific sio_open and remember the opened device in the state field of the netif.
- Parameters:
-
netif the lwip network interface structure for this slipif
- Returns:
- ERR_OK if serial line could be opened, ERR_MEM if no memory could be allocated, ERR_IF is serial line couldn't be opened
- Note:
- netif->num must contain the number of the serial port to open (0 by default). If netif->state is != NULL, it is interpreted as an u8_t pointer pointing to the serial port number instead of netif->num.

| void slipif_poll | ( | struct netif * | netif ) |
Polls the serial device and feeds the IP layer with incoming packets.
- Parameters:
-
netif The lwip network interface structure for this slipif
Definition at line 427 of file lwip_slipif.c.
| void slipif_process_rxqueue | ( | struct netif * | netif ) |
Feeds the IP layer with incoming packets that were receive.
- Parameters:
-
netif The lwip network interface structure for this slipif
Definition at line 449 of file lwip_slipif.c.
| void slipif_received_byte | ( | struct netif * | netif, |
| u8_t | data | ||
| ) |
Process a received byte, completed packets are put on a queue that is fed into IP through slipif_process_rxqueue().
This function can be called from ISR if SYS_LIGHTWEIGHT_PROT is enabled.
- Parameters:
-
netif The lwip network interface structure for this slipif data received character
Definition at line 526 of file lwip_slipif.c.
| void slipif_received_bytes | ( | struct netif * | netif, |
| u8_t * | data, | ||
| u8_t | len | ||
| ) |
Process multiple received byte, completed packets are put on a queue that is fed into IP through slipif_process_rxqueue().
This function can be called from ISR if SYS_LIGHTWEIGHT_PROT is enabled.
- Parameters:
-
netif The lwip network interface structure for this slipif data received character len Number of received characters
