Data Fields
unsigned int	baseAddr
unsigned int	intNum
unsigned int	intPriority

Detailed Description

I2CTiva Hardware attributes.

The baseAddr and intNum fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For TivaWare these definitions are found in:

• inc/hw_memmap.h
• inc/hw_ints.h

intPriority is the I2C peripheral's interrupt priority, as defined by the underlying OS. In the case of SYS/BIOS, intPriority is passed unmodified to Hwi_create().

A sample structure is shown below:

const I2CTiva_HWAttrs i2cTivaHWAttrs[] = {
    {
        .baseAddr = I2C1_BASE,
        .intNum = INT_I2C1,
        .intPriority = (~0)
    },
    {
        .baseAddr = I2C3_BASE,
        .intNum = INT_I2C3,
        .intPriority = (~0)
    },
};
