STM32 buzzer - library function

It should be noted that when using the template of the library function, you cannot apply the register operation randomly. I wanted to use a big move before but ended up making a fool of myself. The experimental requirements here are that the green light is on and the buzzer sounds, the red light is on and the buzzer stops, and the buzzer sounds every half a second. I will not give the LED file here, but mainly release the beep file. The PF8 port is operated here.

1.beep.h

#ifndef __BEEP_H

#define __BEEP_H

#include "sys.h"

#define BEEP PFout(8)

void beep_init(void);

#endif

2.beep.c

#include "beep.h"

void beep_init()

{

    GPIO_InitTypeDef GPIO_InitStructure;

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 ;

    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;

    GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;

    GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;

    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;

    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOF, ENABLE);

    GPIO_Init(GPIOF, &GPIO_InitStructure);

    GPIO_SetBits(GPIOF, GPIO_Pin_8);

}

3.main.c

#include "stm32f4xx.h"

#include "usart.h"

#include "delay.h"

#include "led.h"

#include "beep.h"

int main(void)

{

uart_init(115200);

delay_init(84);

  led_heat();

  beep_init();

  while(1){

    GPIO_ResetBits(GPIOF, GPIO_Pin_9);

    GPIO_SetBits(GPIOF, GPIO_Pin_10);

    GPIO_ResetBits(GPIOF, GPIO_Pin_8);

    delay_ms(500);

    GPIO_SetBits(GPIOF, GPIO_Pin_9);

    GPIO_ResetBits(GPIOF, GPIO_Pin_10);

    GPIO_SetBits(GPIOF, GPIO_Pin_8);

    delay_ms(500);

}
