I2CMSP432.h File Reference

Detailed Description

I2C driver implementation for the EUSCI controller on MSP432.

============================================================================

This I2C driver implementation is designed to operate on a EUCSI controller in I2C mode. The I2CMSP432 header file should be included in an application as follows:

#include <ti/drivers/I2C.h>
#include <ti/drivers/I2CMSP432.h>

---

#include <stdint.h>
#include <stdbool.h>
#include <ti/drivers/I2C.h>
#include <ti/drivers/ports/HwiP.h>
#include <ti/drivers/ports/SemaphoreP.h>
#include <ti/drivers/Power.h>

Typedef Documentation

typedef enum I2CMSP432_Mode I2CMSP432_Mode

I2CMSP432 mode.

This enum defines the state of the I2C driver's state-machine. Do not modify.

typedef struct I2CMSP432_HWAttrs I2CMSP432_HWAttrs

I2CMSP432 Hardware attributes These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP430Ware these definitions are found in:

• i2c.h

A sample structure is shown below:

const I2CMSP432_HWAttrs i2cMSP432HWAttrs[] = {
    {
        .baseAddr = EUSCI_B0_BASE,
        .intNum = INT_EUSCIB0,
        .intPriority = (~0),
        .clockSource = EUSCI_B_I2C_CLOCKSOURCE_SMCLK
    }
};

typedef struct I2CMSP432_Object I2CMSP432_Object

I2CMSP432 Object.

The application must not access any member variables of this structure!

Enumeration Type Documentation

enum I2CMSP432_Mode
