Note that since NetDev_WiFi_SPI_WrRd() 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_ChipSelEn() should be called only after the SPI lock has been acquired by calling NetDev_WiFi_SPI_Lock().
• 2 Since each network device requires a unique NetDev_WiFi_SPI_WrRd(), it is recommended that each device’s NetDev_WiFi_SPI_WrRd() function be named using the following convention:

  NetDev_WiFi_[Device]SPI_WrRd[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)
