Functions | |
ATCA_STATUS | hal_swi_discover_buses (int swi_buses[], int max_buses) |
discover swi buses available for this hardware this maintains a list of logical to physical bus mappings freeing the application.This function is currently not supported. of the a-priori knowledge More... | |
ATCA_STATUS | hal_swi_discover_devices (int bus_num, ATCAIfaceCfg cfg[], int *found) |
discover any CryptoAuth devices on a given logical bus number.This function is curently not supported. More... | |
ATCA_STATUS | hal_swi_init (void *hal, ATCAIfaceCfg *cfg) |
hal_swi_init manages requests to initialize a physical interface. It manages use counts so when an interface has released the physical layer, it will disable the interface for some other use. You can have multiple ATCAIFace instances using the same bus, and you can have multiple ATCAIFace instances on multiple swi buses, so hal_swi_init manages these things and ATCAIFace is abstracted from the physical details.
