用stm32f103c8t6驱动蜂鸣器,代码似乎运行不起来
基于new bing的编写参考:
你好!根据你提供的代码逐行分析:
希望以上分析能够帮助你解决问题。
请注意,以下代码仅供参考,可能需要根据实际情况进行修改。
#include "stm32f10x.h"
#include "Delay.h"
int s, t;
int main(void)
{
// 使能时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC | RCC_APB2Periph_GPIOB, ENABLE);
// 配置 GPIOC Pin5 引脚
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_2MHz;
GPIO_Init(GPIOC, &GPIO_InitStructure);
// 配置 GPIOC Pin13 引脚
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13;
GPIO_Init(GPIOC, &GPIO_InitStructure);
// 配置 GPIOC Pin6 引脚
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
GPIO_Init(GPIOC, &GPIO_InitStructure);
s = 0;
t = 0;
while(1)
{
// 控制蜂鸣器的发声
GPIO_SetBits(GPIOC, GPIO_Pin_13);
Delay_s(1);
GPIO_ResetBits(GPIOC, GPIO_Pin_13);
Delay_s(1);
// 判断输入引脚输入电平,并对计数器进行累加
if(GPIO_ReadInputDataBit(GPIOC, GPIO_Pin_6) == Bit_RESET)
{
s += 1;
Delay_s(1);
}
else
{
t += 1;
Delay_s(1);
}
// 当计数器 s 大于等于 5400 时,开启蜂鸣器 5 秒钟
if(s >= 5400)
{
GPIO_SetBits(GPIOC, GPIO_Pin_5);
Delay_s(5);
GPIO_ResetBits(GPIOC, GPIO_Pin_5);
s = 0;
}
// 当计数器 t 大于等于 300 时,开启蜂鸣器 5 秒钟,并将计数器 s 和 t 归零
if(t >= 300)
{
GPIO_SetBits(GPIOB, GPIO_Pin_5);
Delay_s(5);
GPIO_ResetBits(GPIOB, GPIO_Pin_5);
Delay_s(5);
s = 0;
t = 0;
}
}
}
答案参考ChatGPT Plus版,整理汇总。希望能帮助你解决问题
从您提供的代码来看,存在一些问题可能导致代码无法正确运行:
缺少头文件:在代码开头部分,需要包含相关的头文件,例如 "stm32f10x_gpio.h" 和 "stm32f10x_rcc.h",以便正确使用STM32的库函数。
引脚初始化错误:在初始化蜂鸣器引脚时,您使用了 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5
,但根据代码注释,应该是GPIOC的第13个引脚(即 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_13
)。
输入引脚读取错误:在条件判断中使用了 GPIO_ReadInputDataBit(GPIOB,GPIO_Pin_6)
,但您没有初始化GPIOB的相应引脚,而应该是使用GPIOC的第6个引脚。
延迟函数未实现:根据代码中的 Delay_s(1)
和 Delay_s(5)
,需要自定义延迟函数Delay_s来实现对应的延迟操作。
请注意以上问题并进行相应的修正。同时,确保您的开发环境中已正确配置并连接STM32开发板,以便进行程序的下载和运行。
你好,你这个代码也没排版,参考个别人的代码进行调试吧,你的蜂鸣器没响的原因是你没给方波,你设置输入的代码第29行不用写,输入模式没有速度一说。还有你的这个Delay_s模拟得不够好,导致你的蜂鸣器方波没能很好体现出来,你参考前辈的代码试试看呢

本次设计的基于stm32f103c8t6浊度计主要由硬件部分加软件部分组成
硬件部分主要是IR333光源发射部分+红外接收管光源接受部分+放大电路+stm32f103c8t6主控芯片+lcd1602显示模块组成
软件部分主要是通过stm32cubemx配置管脚之后添加adc通道函数、lcd1602写命令函数、lcd1602读数据函数等生成的
针对该问题,可以采用如下步骤:
#define LED_GPIO_Port GPIOA
#define LED_Pin GPIO_PIN_5
static void MX_GPIO_Init(void)
{
/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOA_CLK_ENABLE();
/*Configure GPIO pin Output Level */
HAL_GPIO_WritePin(LED_GPIO_Port, LED_Pin, GPIO_PIN_RESET);
/*Configure GPIO pin : LED_Pin */
GPIO_InitTypeDef GPIO_InitStruct = {0};
GPIO_InitStruct.Pin = LED_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(LED_GPIO_Port, &GPIO_InitStruct);
}
其中,GPIO_MODE_OUTPUT_PP
表示输出模式,GPIO_InitStruct.Pull
设置为GPIO_NOPULL
表示不采用上拉或下拉。
/* USER CODE BEGIN WHILE */
while (1)
{
HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);
HAL_Delay(500);
}
/* USER CODE END WHILE */
其中,HAL_GPIO_TogglePin
函数用来切换引脚状态,实现LED闪烁。HAL_Delay
函数用来实现延时,以控制LED闪烁频率。
完整代码如下:
