LL_GPIO_ResetOutputPin(GPIO下面是一个使用EasyExcel导出多个sheet的示例代码：

public void exportExcelWithMultipleSheets(HttpA, TRIG_PIN);
  
  while (!LL_GPIO_IsInputPinSet(GPIOA, ECHO_PIN)) {}
  LL_TIM_EnableCounterServletResponse response) {
    try {
        response.setContentType("application/vnd.ms-excel");
        response.setCharacterEncoding("utf-8");
        String fileName(TIMER);
  while (LL_GPIO_IsInputPinSet(GPIOA, ECHO_PIN)) {}
  LL_TIM_DisableCounter(TIMER);
 = URLEncoder.encode("多个Sheet的Excel文件", "UTF-8");
        response.setHeader("Content-disposition", "attachment;filename  
  uint32_t elapsed = LL_TIM_GetCounter(TIMER);
  float distance = (elapsed * 0.0343) / =" + fileName + ".xlsx");

        OutputStream outputStream = response.getOutputStream();

        ExcelWriter excelWriter = EasyExcel.write(outputStream).build();

2.0;
  
  return (uint32_t)distance;
}

int main(void)
{
  LL_GPIO_InitTypeDef GPIO_InitStruct = {0};
  LL_TIM_InitTypeDef TIM_InitStruct = {0};

  LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM        // 写入第一个Sheet
        WriteSheet sheet1 = EasyExcel.writerSheet(0, "Sheet1").head(Student.class).2);
  LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_GPIOA);

  GPIO_InitStruct.Pin = TRIG_PIN;
build();
        List<Student> students1 = getStudents1(); // 获取第一个Sheet的数据
        excelWriter.write(students1,  GPIO_InitStruct.Mode = LL_GPIO_MODE_OUTPUT;
  GPIO_InitStruct.Speed = LL_GPIO_SPEED_FREQ_LOW;
  LL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  GPIO_InitStruct.Pin = ECHO_PIN;
  GPIO_InitStruct.Mode = LL_GPIO_MODE_INPUT;
  GPIO_InitStruct.Pull = LL sheet1);

        // 写入第二个Sheet
        WriteSheet sheet2 = EasyExcel.writerSheet(1, "Sheet2")._GPIO_PULL_NO;
  LL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  TIM_InitStruct.Prescaler = 0;
  TIM_InitStruct.Counterhead(Teacher.class).build();
        List<Teacher> teachers = getTeachers(); // 获取第二个Sheet的数据
        excelWriterMode = LL_TIM_COUNTERMODE_UP;
  TIM_InitStruct.Autoreload = 0xFFFFFFFF;
  LL_TIM_Init(TIMER, &TIM.write(teachers, sheet2);

        // 关闭ExcelWriter
        excelWriter.finish();
        outputStream.flush();
        outputStream.close();
   _InitStruct);
  LL_TIM_EnableIT_UPDATE(TIMER);

  while (1)
  {
    uint32_t distance = measureDistance();
  }
}

void TIM2_IRQHandler(void)
{
  if (LL_TIM_IsActiveFlag_UPDATE(TIMER) == 1)
  {
    LL_TIM } catch (IOException e) {
        e.printStackTrace();
    }
}

private List<Student> getStudents1() {
    // 获取第一个Sheet_ClearFlag_UPDATE(TIMER);
  }
}

3. 与第一个示例类似，但使用 HAL 库和 DMA 来的数据
// ...
}

private List<Teacher> getTeachers() {
// 获取第二个Sheet的数据
// ...
读取定时器计数器的值。

在 CubeMX 中选择 STM32F103VCT6 芯片，然后按}

代码中首先设置了响应头，然后创建一个ExcelWriter实例。接着分别创建了两照以下步骤进行配置：

- 在 Pinout 标签页中，将 PA0 配置为 GPIO_Output，将 PA1 配个WriteSheet实例，分别用于写入两个Sheet的数据。最后通过ExcelWriter将数据写入Excel文件置为 GPIO_Input。
- 在 Configuration 标签页中，选择 SYSCLK 为 HSE，选择 HSE 值为 8 MHz，并关闭ExcelWriter。
