    I have Timer2 running in PWM mode at 8Khz. I need to turn it on and off to run a buzzer. This works, but only once. I am setting and clearing bit 2^15 in the TIM2_CR1 register during an interrupt on Timer3.

    Any suggestions?

    My bad. I called GPIO_DeInit to set up other bits in the port that held the PWM bit. DeInit resets all port bit definitions.
