STM32F051C8T6指纹开led灯详细代码，STMCubeMX生成

以下是使用STMCubeMX生成的STM32F051C8T6指纹开LED灯的详细代码：

1.首先，在STMCubeMX中创建一个新的工程，并选择STM32F051C8T6微控制器。

2.在“Pinout”选项卡中，将PB0设置为输出模式，并将其命名为“LED”。

3.在“Configuration”选项卡中，选择“USART1”，并配置相应的波特率、数据位、停止位和校验位。

4.在“Project Manager”选项卡中，选择“Generate Code”并生成代码。

5.在生成的代码中，找到“main.c”文件，并在其中添加以下代码：

#include "main.h"
#include "stdio.h"
#include "string.h"

UART_HandleTypeDef huart1;

void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_USART1_UART_Init(void);

int main(void)
{
  HAL_Init();
  SystemClock_Config();
  MX_GPIO_Init();
  MX_USART1_UART_Init();
  
  char buffer[100];
  sprintf(buffer, "AT\r\n");
  HAL_UART_Transmit(&huart1, (uint8_t *)buffer, strlen(buffer), 1000);
  HAL_Delay(1000);
  
  sprintf(buffer, "AT+LED=1\r\n");
  HAL_UART_Transmit(&huart1, (uint8_t *)buffer, strlen(buffer), 1000);
  HAL_Delay(1000);
  
  sprintf(buffer, "AT+LED=0\r\n");
  HAL_UART_Transmit(&huart1, (uint8_t *)buffer, strlen(buffer), 1000);
  HAL_Delay(1000);
  
  while (1)
  {
  }
}

  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

  RCC_OscInitStruct.PLL.PREDIV = RCC_PREDIV_DIV1;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    Error_Handler();
  }

  */
  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
                              |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;

  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_1) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_USART1_UART_Init(void)
{
  huart1.Instance = USART1;
  huart1.Init.BaudRate = 9600;
  huart1.Init.WordLength = UART_WORDLENGTH_8B;
  huart1.Init.StopBits = UART_STOPBITS_1;
  huart1.Init.Parity = UART_PARITY_NONE;
  huart1.Init.Mode = UART_MODE_TX_RX;
  huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
  huart1.Init.OverSampling = UART_OVERSAMPLING_16;
  if (HAL_UART_Init(&huart1) != HAL_OK)
  {
    Error_Handler();
  }
}

static void MX_GPIO_Init(void)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};

  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOA_CLK_ENABLE();
  __HAL_RCC_GPIOB_CLK_ENABLE();

  /*Configure GPIO pin Output Level */
  HAL_GPIO_WritePin(LED_GPIO_Port, LED_Pin, GPIO_PIN_RESET);

  /*Configure GPIO pin : LED_Pin */
  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);
}

void Error_Handler(void)
{
  /* User code here */
}

6.编译并下载代码到STM32F051C8T6微控制器中，然后连接指纹模块。

7.在串口助手中输入“AT”命令，确保指纹模块能够正常通信。

8.然后，输入“AT+LED=1”命令，LED灯将亮起。

9.输入“AT+LED=0”命令，LED灯将熄灭。

以上就是使用STMCubeMX生成的STM32F051C8T6指纹开LED灯的详细代码。
