WIZCHIP_WRITE()

void WIZCHIP_WRITE	(	uint32_t	AddrSel,
		uint8_t	wb
	)

It writes 1 byte value to a register.

Returns

void

WIZCHIP_READ_BUF()

void WIZCHIP_READ_BUF	(	uint32_t	AddrSel,
		uint8_t *	pBuf,
		datasize_t	len
	)

It reads sequentail data from registers.

Parameters

AddrSel	Register address
pBuf	Pointer buffer to read data
len	Data length

Returns

void

WIZCHIP_WRITE_BUF()

void WIZCHIP_WRITE_BUF	(	uint32_t	AddrSel,
		uint8_t *	pBuf,
		datasize_t	len
	)

It writes sequential data to registers.

Parameters

AddrSel	Register address
pBuf	Pointer buffer to write data
len	Data length

Returns

void

wiz_send_data()

void wiz_send_data	(	uint8_t	sn,
		uint8_t *	wizdata,
		datasize_t	len
	)

It saves data to be sent in the SOCKETn TX buffer.

This function reads first _Sn_TX_WR_
and starts to copy wizdata from _Sn_TX_WR_ address of SOCKETn TX buffer as many as len.
After it is completed to copy <wizdata,
It increases _Sn_TX_WR_ as many as len.

Parameters

sn	SOCKETn. It should be 0 ~ _WIZCHIP_SOCK_NUM_.
wizdata	Pointer buffer to write data
len	Data length

See also

wiz_recv_data()

wiz_recv_data()

void wiz_recv_data	(	uint8_t	sn,
		uint8_t *	wizdata,
		datasize_t	len
	)

It reads the received data from the SOCKETn RX buffer and copies the data to your system memory specified by wizdata.

This function reads first _Sn_RX_RD_
and starts to copy the received data to wizdata as many as len.
After it is completed to copy the received data,
It increases _Sn_RX_RD_ as many as len.

Parameters

sn	SOCKETn. It should be 0 ~ _WIZCHIP_SOCK_NUM_.
wizdata	Pointer buffer to read data
len	Data length

See also

wiz_send_data()

wiz_recv_ignore()

void wiz_recv_ignore	(	uint8_t	sn,
		datasize_t	len
	)

It discards the received data in the SOCKETn RX buffer.

This function discards the received data by increasing _Sn_RX_RD_ as manay as len without coping the data.

Parameters

sn	SOCKETn. It should be 0 ~ _WIZCHIP_SOCK_NUM_.
len	Data length
