Data Fields

uint32_t	pinPwmMode
uint32_t	gpioBaseAddr
uint8_t	gpioPinIndex

Detailed Description

PWMTiva Hardware attributes.

These 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
• driverlib/gpio.h
• driverlib/pwm.h

A sample structure is shown below:

const PWMTiva_HWAttrs PWMTivaHWAttrs[] = {
    {
        .pwmBaseAddr = PWM0_BASE,
        .pwmOutput = PWM_OUT_0,
        .pwmGenOpts = PWM_GEN_MODE_DOWN | PWM_GEN_MODE_DBG_RUN,
        .pinPwmMode = GPIO_PF0_M0PWM0,
        .gpioBaseAddr = GPIO_PORTF_BASE,
        .gpioPinIndex = GPIO_PIN_0
    }
};

Field Documentation

uint32_t PWMTiva_HWAttrsV1::pwmBaseAddr

< PWM peripheral base address (ex.: PWM0_BASE, PWM1_BASE, etc.). Encoded PWM offset address (ex.: PWM_OUT_0, PWM_OUT_5, etc.).

uint32_t PWMTiva_HWAttrsV1::pwmOutput
