stm32h750 dcmi ov5640 调试

STM32H750获取OV5640摄像头图像及上位机解码（一维码&二维码）

1. 目的

针对静止拍摄图像场景，实现STM32H750对500万像素OV5640摄像头进行图像捕获，并通过串口将数据送到上位机软件进行解码。
本文可作为STM32H7及STM32F7系列驱动OV5640摄像头的代码参考，本例程输出分辨率（640×480）是通过DCMI的CROP方式从大图片中“剪”出，使用者也可以做不同设置“剪"出不同分辨率的图片。

2. 场景参数说明

  1. 上位机与STM32H750通过USB全速虚拟串口（可用12000000波特率）或UART串口（230400波特率）通讯及接收图像数据。
  2. STM32H750通过DCMI总线接口与OV5640摄像头DVP接口连接，通过IIC总线与OV5640 SCCB配置端口连接，并通过GPIO连接控制摄像头端的Reset和PowerDown管脚。
  3. STM32H750从OV5640摄像头获取640×480分辨率的RGB图像，本实验不针对有SRAM扩展的场景，也不针对直接传送数据至嵌入式LCD显示的场景,因此，内部SRAM分区用于存放一帧数据*（640×480×2 bytes)的空间不足，因此，利用STM32 DCMI CROP功能，获取多帧图像的不同部分实现拼接效果，并最终将一整帧数据传送到上位机。
  4. 开发环境为STM32CUBEIDE（HAL库）

3. 通讯协议

  1. 上位机通过串口发送0x01指令到STM32, STM32接收指令后，回复0x55 0xaa xx三个字节，其中0x55 0xaa指示有效的回复，xx为摄像头类型说明，便于上位机程序进行后续数据的识别处理，当前xx==0x03为OV5640摄像头。
  2. STM32从OV5640摄像头分帧获取不同部分并发送整帧640×480×2的RGB565数据到上位机。
  3. 上位机进行图像的显示，并可选进行一维码和二维码的识别（基于zbar开源库）。
  4. 简化型设计，无校验方式

4. STM32H750时钟配置

对于需要STM32H750输出24MHz时钟给OV5640摄像头模块的场景，可以用STM32 MCO功能输出24MHz时钟。如果摄像头模块自带晶振，不需要STM32提供时钟。

6. 摄像头接口配置

DCMI接口：
STM32H7的HAL库DCMI接口,从1.8版本升级1.9以上版本后，配置及函数存在问题。因此这里的参数配置（“Parameter Settings”）部分，会在程序里面重新配置。

而其它部分正常配置：

需要单独对DCMI接口的HSYNC和VSYNC做输入GPIO的配置：
在这里插入图片描述

OV5640的SCCB接口时序通过STM32的GPIO管脚模拟，不采用专用的IIC管脚。OV5640的Reset和PowerDown信号，也通过2个GPIO进行管理控制。

保存，并生成初始代码，再进行功能代码的编写。

以上代码实现对OV5640的接口访问, 实现OV5640初始化（配置为640×80 RGB模式），并持续向外输出图像。

8. DMA发送机制

STM32通过串口接收指令，程序里设计一个标识变量scmd用于指示接收到的指令。需要在USB虚拟串口的接收函数里进行处理：
在这里插入图片描述

static int8_t CDC_Receive_FS(uint8_t* Buf, uint32_t *Len)
{
  /* USER CODE BEGIN 6 */
	  extern uint8_t scmd;
	  if(Buf[0]==0x01) scmd=0x01;

  USBD_CDC_SetRxBuffer(&hUsbDeviceFS, &Buf[0]);
  USBD_CDC_ReceivePacket(&hUsbDeviceFS);
  return (USBD_OK);
  /* USER CODE END 6 */
}

以及在USART1的接收中断里进行处理：
在这里插入图片描述

void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
	if (huart ==  &huart1)
	{

		if (aRxBuffer==0x01)
		{
			scmd = 0x02;
			aRxBuffer=0x00;

			HAL_UART_Receive_IT(&huart1, (uint8_t *)&aRxBuffer, 1);
		}
		else
		{

		HAL_UART_Receive_IT(&huart1, (uint8_t *)&aRxBuffer, 1);

		}


	}
      return;

}

STM32向上位机发送图像数据采用USB虚拟串口或串口DMA方式，程序里设计一个标识变量tx_busy，在当前DMA发送完后指示状态：
在这里插入图片描述

static int8_t CDC_TransmitCplt_FS(uint8_t *Buf, uint32_t *Len, uint8_t epnum)
{
  uint8_t result = USBD_OK;
  /* USER CODE BEGIN 13 */
  extern uint8_t tx_busy ;
  tx_busy = 0;

  UNUSED(Buf);
  UNUSED(Len);
  UNUSED(epnum);
  /* USER CODE END 13 */
  return result;
}

同样，对USART1的DMA发送完处理：
在这里插入图片描述

void HAL_UART_TxCpltCallback(UART_HandleTypeDef *huart)
{
  extern uint8_t tx_busy;
	if (huart ==  &huart1)
	{
		tx_busy = 0;
	}

9. DCMI DMA地址自增方式

初始化DCMI DMA配置时，如将接收地址设置为不自增方式。后续的图像捕获需要工作在DMA接收地址自增方式，因此单独设计两个函数可用于切换。

void DCMI_DMA_MemInc_En(void)
{
    HAL_DMA_DeInit(&hdma_dcmi);

    hdma_dcmi.Init.MemInc = DMA_MINC_ENABLE;
    if (HAL_DMA_Init(&hdma_dcmi) != HAL_OK)
    {
      Error_Handler();
    }
}

void DCMI_DMA_MemInc_Den(void)
{
    HAL_DMA_DeInit(&hdma_dcmi);
    hdma_dcmi.Init.MemInc = DMA_MINC_DISABLE;

10. 初始化修正函数

按照1.8版本HAL库，设计DCMI的初始化修正函数：

void PY_DCMI_Full_Init(void)
{
  hdcmi.Instance = DCMI;
  hdcmi.Init.SynchroMode = DCMI_SYNCHRO_HARDWARE;
  hdcmi.Init.PCKPolarity = DCMI_PCKPOLARITY_RISING;
  hdcmi.Init.VSPolarity = DCMI_VSPOLARITY_HIGH;
  hdcmi.Init.HSPolarity = DCMI_HSPOLARITY_LOW;
  hdcmi.Init.CaptureRate = DCMI_CR_ALL_FRAME;
  hdcmi.Init.ExtendedDataMode = DCMI_EXTEND_DATA_8B;
  hdcmi.Init.JPEGMode = DCMI_JPEG_DISABLE;
  hdcmi.Init.ByteSelectMode = DCMI_BSM_ALL;
  hdcmi.Init.ByteSelectStart = DCMI_OEBS_ODD;
  hdcmi.Init.LineSelectMode = DCMI_LSM_ALL;
  hdcmi.Init.LineSelectStart = DCMI_OELS_ODD;
  if (HAL_DCMI_Init(&hdcmi) != HAL_OK)
  {
    Error_Handler();
  }
}

11. 主函数代码

在程序跑起来后，会先对OV5640接口进行典型寄存器读取并USART1串口输出，用于识别接口时序是否正常。然后进入命令等待，接收到指令后，再从OV5640输出的图像中截取数据串口DMA输出。
