Socket APIs: Basic I/O function

It reads 1 byte value from a register.

Parameters

AddrSel

Register address

Returns

The value of register

It writes 1 byte value to a register.

Parameters

AddrSel	Register address
wb	Write data

Returns

void

It reads sequence data from registers.

Parameters

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

It writes sequence data to registers.

Parameters

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

It copies data to internal TX memory.

This function reads the Tx write pointer register and after that, it copies the wizdata(pointer buffer) of the length of len(variable) bytes to internal TX memory and updates the Tx write pointer register. This function is being called by send() and sendto() function also.

Parameters

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

wiz_recv_data()

It copies data to your buffer from internal RX memory.

This function read the Rx read pointer register and after that, it copies the received data from internal RX memory to wizdata(pointer variable) of the length of len(variable) bytes. This function is being called by recv() also.

Parameters

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

See also

wiz_send_data()

It discard the received data in RX memory.

It discards the data of the length of len(variable) bytes in internal RX memory.

Parameters

(uint8_t)sn	Socket number. It should be 0 ~ _WIZCHIP_SOCK_NUM_.
len	Data length
