this is the code I am using to generate PWM on pin PF1 using timer.
It is giving following errors on line GPIOPinConfigure(GPIO_PF1_T0CCP1) as ::
1)'GPIO_PF1_T0CCP1' undeclared
2)Symbol 'GPIO_PF1_T0CCP1' could not be resolved

// The TIMER0 peripheral must be enabled for use.
SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER0);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
GPIOPinTypeTimer(GPIO_PORTF_BASE, GPIO_PIN_1);
GPIOPinConfigure(GPIO_PF1_T0CCP1);
TimerConfigure(TIMER0_BASE, TIMER_CFG_16_BIT_PAIR | TIMER_CFG_B_PWM);
TimerLoadSet(TIMER0_BASE, TIMER_B, 50000);
TimerEnable(TIMER0_BASE, TIMER_B);
TimerMatchSet(TIMER0_BASE, TIMER_B, 45000);
while(1)

}
}
But if I use hexadecimal value directly from library like this GPIOPinConfigure(0x00050407) instead of GPIOPinConfigure(GPIO_PF1_T0CCP1) it works fine.
