Detailed Description

I2CCC26XX Hardware attributes.

These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For cc26xxware these definitions are found in:

• inc/hw_memmap.h
• inc/hw_ints.h

A sample structure is shown below:

const I2CCC26XX_HWAttrs i2cCC26XXHWAttrs[] = {
    {
       .baseAddr = I2C0_BASE,
       .powerMngrId = PERIPH_I2C0,
       .intNum = INT_I2C,
       .intPriority = (~0),
       .sdaPin = Board_I2C_SDA,
       .sclPin = Board_I2C_SCL,
    },
};

Field Documentation

I2CBaseAddrType I2CCC26XX_HWAttrs::baseAddr

I2C Peripheral's base address

unsigned long I2CCC26XX_HWAttrs::powerMngrId

I2C Peripheral's power manager ID

int I2CCC26XX_HWAttrs::intNum

I2C Peripheral's interrupt vector

uint8_t I2CCC26XX_HWAttrs::intPriority

I2C Peripheral's interrupt priority.

The CC26xx uses three of the priority bits, meaning ~0 has the same effect as (7 << 5). (7 << 5) will apply the lowest priority. (0 << 5) will apply the highest priority.

uint8_t I2CCC26XX_HWAttrs::sdaPin

I2C SDA pin mapping

uint8_t I2CCC26XX_HWAttrs::sclPin

I2C SCL pin mapping
