从带有Nucleo-f401re主板的Lepton FLIR相机获得连续流

我将我的Flir Lepton相机连接到我的主板上，并且我正在尝试连续的图像流，这要归功于程序ThermalView（源代码：https://github.com/groupgets/LeptonModule/tree/master/software/ThermalView）我编译并在我的主板上下载了以下代码：

int main(void)
{

  //HAL_Init();

  /* Configure the system clock */
  SystemClock_Config();

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_DMA_Init();
  MX_I2C1_Init();
  MX_SPI1_Init();
  MX_USART1_UART_Init();
  MX_USART2_UART_Init();
  SystemClock_Config();

  leptonEnd();
  // LEPTON VDD OFF
  HAL_Delay(1000);
  // LEPTON VDD ON
  HAL_Delay(185);

  LeptonConfigure_I2C(); 

  while(1)
  {
    LeptonReadFrame();
    frameToPc(); 
  }
}

// Output image buffer to USART2
void frameToPc()
{
  static uint8_t frameSkipper = 0;

  uint8_t timeStamp = (HAL_GetTick() - last_frame_millis); // calculate time passed since last been here

  last_frame_millis = HAL_GetTick();



  if(frameSkipper==4)
  {
    //PSEDO//
    //IMGtoRGB();

    ////////
    uint8_t thermalView_header[] = {0xDE,0xAD,0xBE,0xEF}; // 4-byte header for ThermalView application
    HAL_Delay(1000);
    HAL_UART_Transmit_DMA(&huart2, &thermalView_header[0], 4); // print header

    while(huart2.gState != HAL_UART_STATE_READY); // wait for transmission to complete

    HAL_UART_Transmit_DMA(&huart2, &IMG[0], LEPTON_IMG_SIZE_BYTES);

    frameSkipper = 0;
  }

  frameSkipper++;
}uint8_t LeptonReadFrame()
{  
  uint8_t i, frame_number, frame_complete=0;
  uint16_t bad_frame_counter=0;

  while(!frame_complete)
  {
    leptonBegin();

    HAL_SPI_Receive(&hspi1, &FramePacket[0], LEPTON_PACKET_LENGTH, 1000);  // READ LINE    

    leptonEnd();

    //HAL_UART_Transmit(&huart2,  &FramePacket[0], LEPTON_PACKET_LENGTH, 1000); // PRINT LINE

    if( (FramePacket[0] & 0x0f) != 0x0f ) // not discard frame
    {
       frame_number = FramePacket[1];

       if(frame_number < 60) // valid frame
       {
         bad_frame_counter = 0; 

         for(i= 0; i<LEPTON_PACKET_CONTENT_LENGTH; i++)
         {
           IMG[frame_number*LEPTON_PACKET_CONTENT_LENGTH+i] = FramePacket[i+4]; // copy line into IMG buffer, ignoring ID and CRC
         }
       }
       else
       {
         bad_frame_counter++;
       }

       if(frame_number == 59)
       {
          frame_complete = 1;
       }

       if(bad_frame_counter>1000) // 800 lines = 5 bad frames = resync needed
       {
          bad_frame_counter = 0;
          HAL_Delay(185);  // CS is already disabled so the delay is enougth
       }
    }
  }
  return 1;
}

我成功地获得了一个流，但是我必须在每个帧之间放置1秒的延迟，并且必须跳过我发送到计算机的2帧之间的帧 . 如果您注意代码中的某些错误会阻止提高帧速率，请告诉我 .
