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:
Refer to I2C.h for a complete description of APIs and usage.
#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>

Data Structures | |
struct | I2CMSP432_HWAttrs |
I2CMSP432 Hardware attributes These fields, with the exception of intPriority, are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP430Ware these definitions are found in: More... | |
struct | I2CMSP432_Object |
I2CMSP432 Object. More... | |
Typedefs | |
typedef enum I2CMSP432_Mode | I2CMSP432_Mode |

typedef struct I2CMSP432_HWAttrs | I2CMSP432_HWAttrs |

Enumerations | |
enum | I2CMSP432_Mode { I2CMSP432_IDLE_MODE = 0, I2CMSP432_WRITE_MODE, I2CMSP432_READ_MODE, I2CMSP432_ERROR = 0xFF } |

Variables | |
const I2C_FxnTable | I2CMSP432_fxnTable |
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, with the exception of intPriority, are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP430Ware these definitions are found in:
intPriority is the I2C peripheral's interrupt priority. This driver uses the HwiP port interface, which handles the interrupt priority in the OS appropriate way. In the case of the SYS/BIOS implementation, intPriority is passed unmodified to Hwi_create().
A sample structure is shown below:
typedef struct I2CMSP432_Object I2CMSP432_Object |
I2CMSP432 Object.
The application must not access any member variables of this structure!
