Hi everyone,

I am using STM32F4 Discovery evaluation board and Atollic TrueStudio. My problem is a fast I/O handling i want to generate signal frequency at 84 MHz. I'm getting ~15 MHz if I use

while (1) {
GPIOD->BSRRH = GPIO_Pin_13;
GPIOD->BSRRL = GPIO_Pin_13;
}

How to achieve 84 MHz? Do I need to initialize the timer and pwm?

Thanks
