None.
Notes / Warnings
- 1
NetDev_WiFi_SPI_ChipSelDis() 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_ChipSelDis()
, it is recommended that each device’sNetDev_WiFi_SPI_ChipSelDis()
function be named using the following convention:NetDev_WiFi_[Device]SPI_ChipSelDis[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)
