stm32f103c8t6按键流水灯代码

以下是基于STM32CubeIDE的stm32f103c8t6按键流水灯代码示例：

#include "main.h"

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

int main(void)
{
  HAL_Init();
  SystemClock_Config();
  MX_GPIO_Init();

  uint8_t led_num = 0;
  uint8_t button_state = 0;

  while (1)
  {
    button_state = HAL_GPIO_ReadPin(BUTTON_GPIO_Port, BUTTON_Pin);
    if(button_state == GPIO_PIN_RESET)
    {
      led_num++;
      if(led_num > 7)
      {
        led_num = 0;
      }
    }
    HAL_GPIO_WritePin(LED_0_GPIO_Port, LED_0_Pin, (led_num == 0) ? GPIO_PIN_SET : GPIO_PIN_RESET);
    HAL_GPIO_WritePin(LED_1_GPIO_Port, LED_1_Pin, (led_num == 1) ? GPIO_PIN_SET : GPIO_PIN_RESET);
    HAL_GPIO_WritePin(LED_2_GPIO_Port, LED_2_Pin, (led_num == 2) ? GPIO_PIN_SET : GPIO_PIN_RESET);
    HAL_GPIO_WritePin(LED_3_GPIO_Port, LED_3_Pin, (led_num == 3) ? GPIO_PIN_SET : GPIO_PIN_RESET);
    HAL_GPIO_WritePin(LED_4_GPIO_Port, LED_4_Pin, (led_num == 4) ? GPIO_PIN_SET : GPIO_PIN_RESET);

    HAL_Delay(100);
  }
}

void SystemClock_Config(void)
{
  RCC_OscInitTypeDef RCC_OscInitStruct = {0};
  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

  __HAL_RCC_PWR_CLK_ENABLE();

  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
  RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL9;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    Error_Handler();
  }

  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_SYSCLK|RCC_CLOCKTYPE_PCLK1;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2;
  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
  {
    Error_Handler();
  }
}

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

  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOD_CLK_ENABLE();

  GPIO_InitStruct.Pin = BUTTON_Pin;
  GPIO_InitStruct.Mode = GPIO_MODE_INPUT;
  GPIO_InitStruct.Pull = GPIO_PULLUP;
  HAL_GPIO_Init(BUTTON_GPIO_Port, &GPIO_InitStruct);

  GPIO_InitStruct.Pin = LED_0_Pin|LED_1_Pin|LED_2_Pin|LED_3_Pin
                          |LED_4_Pin|LED_5_Pin|LED_6_Pin|LED_7_Pin;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
}

本示例代码假定：按键连接到PC13，LEDs连接到PC0-PC7。在按下按键时，LEDs将顺序闪烁，直到所有LED都开启，然后重新开始顺序闪烁。
