Detailed Description

CameraCC32XXDMA Hardware attributes.

These fields, with the exception of intPriority, are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For CC32XXWare these definitions are found in:

• inc/hw_memmap.h
• inc/hw_ints.h

intPriority is the Camera peripheral's interrupt priority, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation for usage. If the driver uses the ti.dpl interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way. In the case of the SYS/BIOS port, intPriority is passed unmodified to Hwi_create().

A sample structure is shown below:

const CameraCC32XXDMA_HWAttrs CameraCC32XXDMAHWAttrs[] = {
    {
        .baseAddr = CAMERA_BASE,
        .intNum = INT_CAMERA,
        .intPriority = (~0),
        .channelIndex = UDMA_CH22_CAMERA
    }
};
