Hi,
I am having an issue with inverting one of the PWM. I used a scope to look at my outputs they are both the exact same, while I was attempting to have them be inverts of one another. Any ideas as what could be causing this issue?
//Check mode and set frequency accordingly // if (operatingMode == 0) //Legacy // { Ticks = 2000; //4000; //30KHz //} //else if (operatingMode == 1) //Smart //{ // Ticks = Number_Ticks_Freq(); //} // // Enable the GPIO Peripheral used by PWM (PF0, PF1) // SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF); // // Enable PWM0 // SysCtlPeripheralEnable(SYSCTL_PERIPH_PWM0); while(!SysCtlPeripheralReady(SYSCTL_PERIPH_GPIOF)){}; // //Dividing the clock for PWM use - Will use one for now // SysCtlPWMClockSet(SYSCTL_PWMDIV_1); // //Unlocking the pins // HWREG(GPIO_PORTF_BASE + GPIO_O_LOCK) = GPIO_LOCK_KEY; HWREG(GPIO_PORTF_BASE + GPIO_O_CR) = 0x01; // // Configure GPIO pin for PWM // GPIOPinConfigure(GPIO_PF0_M0PWM0); GPIOPinConfigure(GPIO_PF1_M0PWM1); GPIOPinTypePWM(GPIO_PORTF_BASE, GPIO_PIN_0 | GPIO_PIN_1); // // Configure PWM // PWMGenConfigure(PWM0_BASE, PWM_GEN_0, PWM_GEN_MODE_DOWN | PWM_GEN_MODE_NO_SYNC); // //Setting PWM Period // PWMGenPeriodSet(PWM0_BASE, PWM_GEN_0, Ticks); // //Setting duty cycle // PWMPulseWidthSet(PWM0_BASE, PWM_OUT_0 , ceil(Ticks/2)); //50% duty cycle PWMPulseWidthSet(PWM0_BASE, PWM_OUT_1 , ceil(Ticks/2)); //50% duty cycle // // Enable PWM // PWMGenEnable(PWM0_BASE, PWM_GEN_0); PWMOutputInvert(PWM0_BASE, PWM_OUT_1_BIT, true); PWMOutputState(PWM0_BASE, PWM_OUT_0_BIT | PWM_OUT_1_BIT, true);
