DRV_W25_Initialize Function

SYS_MODULE_OBJ DRV_W25_Initialize
(
    const SYS_MODULE_INDEX drvIndex,
    const SYS_MODULE_INIT *const init
);

Initializes the W25 Driver

This routine initializes the W25 driver making it ready for client to use.

None.

If successful, returns a valid handle to a driver instance object. Otherwise it returns SYS_MODULE_OBJ_INVALID.

// This code snippet shows an example of initializing the W25 Driver
// with W25256JV flash device attached.

SYS_MODULE_OBJ  objectHandle;

const DRV_W25_PLIB_INTERFACE drvW25PlibAPI =
{
    .Write               = QMSPI0_Write,
    .Read                = QMSPI0_Read,
    .DMATransferRead     = QMSPI0_DMATransferRead,
    .DMATransferWrite    = QMSPI0_DMATransferWrite
};

const DRV_W25_INIT drvW25InitData =
{
    .w25Plib         = &drvW25PlibAPI,
};

objectHandle = DRV_W25_Initialize((SYS_MODULE_INDEX)DRV_W25_INDEX, (SYS_MODULE_INIT *)&drvW25InitData);

if (SYS_MODULE_OBJ_INVALID == objectHandle)
{
    // Handle error
}

This routine must be called before any other W25 driver routine is called.

This routine should only be called once during system initialization. This routine will block for hardware access.
