static CPU_INT32U NetDev_WiFi_SPI_Init (NET_IF *p_if,
NET_ERR *p_err); |
Note that since NetDev_WiFi_SPI_Init()
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 This function can configure the SPI mode by accessing the device configuration if no other device’s hardware sahre the same SPI bus.
- 2 Since each network device requires a unique
NetDev_WiFi_SPI_Init()
, it is recommended that each device’sNetDev_WiFi_SPI_Init()
function be named using the following convention:NetDev_WiFi_[Device]SPI_Init[Number]()
[Device]
Network device name or type. For example, 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_Init()
function for the #2 RS9110 wireless device on an Atmel AT91SAM9263-EK should be named NetDev_WiFi_RS9110_SPI_Init2()
, or NetDev_WiFi_RS9110_SPI_Init_2()
with additional underscore optional.
