C++ (Cpp) pll_start Exemples

Exemple #1

Fichier : main.c Projet : Polprzewodnikowy/stm32f4_usb_to_audio

int main(void)
{
	fpu_enable();
	system_init();
	pll_start(CRYSTAL, FREQUENCY);

	gpio_pin_cfg(GPIOD, 12, GPIO_OUT_PP_25MHz);
	gpio_pin_cfg(GPIOD, 13, GPIO_OUT_PP_25MHz);
	gpio_pin_cfg(GPIOD, 14, GPIO_OUT_PP_25MHz);
	gpio_pin_cfg(GPIOD, 15, GPIO_OUT_PP_25MHz);

	USBD_Init(&USB_Dev, USB_OTG_FS_CORE_ID, &USR_desc, &AUDIO_cb, &USR_cb);

	while(1);
}

Exemple #2

Fichier : main.c Projet : FreddieChopin/lpc4330_blink_led

int main(void)
{
	volatile uint32_t count, count_max = 10000000;

	fpu_enable();
	pll_start(CRYSTAL, FREQUENCY);

	LPC_GPIO_PORT->DIR[LED_GPIO] |= LED;	// configure GPIO pin as output

	while (1)
	{
		for (count = 0; count < count_max; count++);	// delay
		LED_bb = 1;
		for (count = 0; count < count_max; count++);	// delay
		LED_bb = 0;
	}

	return 0;
