Detailed Description

Initialisation and other management functions for WHD system.

Function Documentation

uint32_t whd_add_secondary_interface	(	whd_driver_t	whd_drv,
		whd_mac_t *	mac_addr,
		whd_interface_t *	ifpp
	)

Creates a secondary interface.

Parameters

whd_drv	Pointer to handle instance of the driver
mac_addr	MAC address for the interface
ifpp	Pointer to the whd interface pointer

uint32_t whd_deinit ( whd_interface_t ifp )

Shutdown this instance of the wifi driver, freeing all used resources.

Parameters

ifp	Pointer to handle instance of whd interface

Initialize an instance of the WHD driver.

Parameters

whd_driver_ptr	Pointer to Pointer to handle instance of the driver
whd_init_config	Pointer to configuration data that controls how the driver is initialized
resource_ops	Pointer to resource interface to provide resources to the driver initialization process
buffer_ops	Pointer to a buffer interface to provide buffer related services to the driver instance
network_ops	Pointer to a whd_netif_funcs_t to provide network stack services to the driver instance

uint32_t whd_wifi_off ( whd_interface_t ifp )

Turn off the Wi-Fi device.

De-Initialises the required parts of the hardware platform i.e. pins for SDIO/SPI, interrupt, reset, power etc.
De-Initialises the whd thread which arbitrates access to the SDIO/SPI bus

Parameters

ifp	Pointer to handle instance of whd interface

Returns: WHD_SUCCESS if deinitialization is successful, Error code otherwise

Turn on the Wi-Fi device.

Initialise Wi-Fi platform Program various WiFi parameters and modes

Parameters

whd_driver	Pointer to handle instance of the driver
ifpp	Pointer to Pointer to handle instance of whd interface

uint32_t whd_wifi_set_down ( whd_interface_t ifp )

Bring down the Wi-Fi core.

WARNING / NOTE: This brings down the Wi-Fi core and existing network connections will be lost.

Parameters

ifp	Pointer to handle instance of whd interface

uint32_t whd_wifi_set_up ( whd_interface_t ifp )

Brings up the Wi-Fi core.

Parameters

ifp	Pointer to handle instance of whd interface
