Methods | |
![]() |
Initializes an AT45 instance and configures SPI chip select register. |
![]() |
This function returns the At45Desc structure corresponding to the device connected It automatically initializes pAt45->pDesc field structure. |
![]() |
This function returns 1 if the At45 driver is not executing any command; otherwise it returns 0. |
![]() |
This function returns the pagesize corresponding to the device connected. |
![]() |
Sends a command to the dataflash through the SPI. |
Macros | |
![]() |
Returns 1 if the device is configured in binary page mode; otherwise 0. |
![]() |
Returns the device ID code. |
![]() |
Returns 1 if the device is ready; otherwise 0. |
