This function is called by a device driver to configure the SPI controller accordingly with device’s SPI setting.

Prototype

Note that since NetDev_WiFi_SPI_Cfg() is accessed only by function pointer via a BSP interface structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.

Required Configuration

None.

Notes / Warnings

• 1 NetDev_WiFi_SPI_Cfg() should be called only after the SPI lock has been acquired by calling NetDev_WiFi_SPI_Lock().
• 2 If no other device’s hardware share the same SPI controller, the configuration can be applied only at the initialization when NetDev_WiFi_SPI_Init() is called.
• 3 Since each network device requires a unique NetDev_WiFi_SPI_ChipSelEn(), it is recommended that each device’s NetDev_WiFi_SPI_ChipSelEn() function be named using the following convention:

NetDev_WiFi_[Device]SPI_ChipSelEn[Number]()

[Device]

Network device name or type, e.g. RS9110 (optional if the development board does not support multiple devices)

[Number]

Network device number for each specific instance of device (optional if the development board does not support multiple instances of the specific device)

For example, the NetDev_WiFi_SPI_ChipSelEn() function for the #2 RS9110 wireless device on an Atmel AT91SAM9263-EK should be named NetDev_WiFi_RS9110_SPI_ChipSelEn2(), or NetDev_WiFi_RS9110_SPI_ChipSelEn_2() with additional underscore optional.
