Detailed Description

I2CMSP432E4 Hardware attributes.

The baseAddr and intNum fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP432E4 driverlib these definitions are found in:

ti/devices/msp432e4/inc/msp432e4x1y.h

intPriority is the I2C 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. For example, for SYS/BIOS applications, refer to the ti.sysbios.family.arm.m3.Hwi documentation for SYS/BIOS usage of interrupt priorities. 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 I2CMSP432E4_HWAttrs i2cMSP432E4HWAttrs[] = {
    {
        .baseAddr = I2C7_BASE,
        .intNum = INT_I2C7,
        .intPriority = (~0),
        .sclPin = I2CMSP432E4_PD0_I2C7SCL,
        .sdaPin = I2CMSP432E4_PD1_I2C7SDA,
        .masterCode = 0x08
    },
    {
        .baseAddr = I2C8_BASE,
        .intNum = INT_I2C8,
        .intPriority = (~0),
        .sclPin = I2CMSP432E4_PA2_I2C8SCL,
        .sdaPin = I2CMSP432E4_PA3_I2C8SDA,
        .masterCode = 0x09
    },
};

Field Documentation

§ baseAddr

uint32_t I2CMSP432E4_HWAttrs::baseAddr

I2C Peripheral's base address

§ intNum

uint32_t I2CMSP432E4_HWAttrs::intNum

I2C Peripheral's interrupt vector

§ intPriority

uint32_t I2CMSP432E4_HWAttrs::intPriority

I2C Peripheral's interrupt priority

§ sclPin

uint32_t I2CMSP432E4_HWAttrs::sclPin

I2C Serial Clock Line pin configuration

§ sdaPin

uint32_t I2CMSP432E4_HWAttrs::sdaPin

I2C Serial Data Line pin configuration

§ masterCode

uint8_t I2CMSP432E4_HWAttrs::masterCode

I2C Master Code. The master code can be between 08h to 0Fh. Each master on a shared bus should use a unique master code. The master code is only used when operating at a bit rate of I2C_3330kHz. Therefore, this parameter is ignored when operating at other bit rates.

The documentation for this struct was generated from the following file:
