    大家好,我是兔子。嵌入式工程师。

    专业角度带你玩转Arduino.

    这次教大家用Arduino UNO来驱动摄像头OV7670拍照。

    1.摄像头OV7670

    ov7670是OmniVision公司生产的一款感光整列,30W像素。

    0adfd861e93e5c3b8daa52b6e1d15aa2.png

    如图所示,就是这个类型芯片的东西。

    然后我们给感光整列配上镜头,加上他的外围电路,就成了某宝热卖的OV7670摄像头模块。

    模块如图所示:

    ff2fc68b3c5c995f67a9afe647d4e5ed.png

    我们这次使用的是OV7670带FIFO的模块。(FIFO芯片->背面图,最大的一个28脚的芯片)

    为什么要用带FIFO的模块呢?因为Arduino UNO速度比较慢,带FIFO可已将摄像头拍摄的数据暂时存在FIFO里,然后我们的Arduino UNO再慢慢的将拍摄的数据读出来,通过串口发送到串口上位机显示。

    FIFO,即first in first out的缩写。在这里,FIFO的速度很快,可以将摄像头的数据暂时存起了。以便我们慢速的CPU将获得的数据慢慢取出来并处理,达到一个类似水库的作用。

    2.接线

    e6625fc23f72da237ad2513db1ad3f1e.png

    我们可以看到Arduino UNO的资源有限,摄像头除了串口(管脚0,1)及管脚13没有用到,其余管脚都用上了。

    所以数据只能通过串口上传到电脑上显示。

    OV7670 D0 ->Arduino 3

    OV7670 D1 ->Arduino 4

    OV7670 D2 ->Arduino 5

    OV7670 D3 ->Arduino 6

    OV7670 D4 ->Arduino 7

    OV7670 D5 ->Arduino 8

    OV7670 D6 ->Arduino 9

    OV7670 D7 ->Arduino 10

    OV7670 FIFIO_RCK -> Arduino A0

    OV7670 FIFIO_OE -> Arduino A1

    OV7670 FIFIO_WR -> Arduino A2

    OV7670 FIFIO_RRST -> Arduino A3

    OV7670 SIO_C -> Arduino A5 (管脚不可调整为其他管脚)

    OV7670 SIO_D -> Arduino A4 (管脚不可调整为其他管脚)

    OV7670 FIFIO_WRST -> Arduino 11

    OV7670 VSYNC -> Arduino 2 (管脚不可调整为其他管脚)

    OV7670 RESET -> Arduino 12

    OV7670 3.3V -> Arduino 3.3V

    OV7670 GND -> Arduino GND

    其余摄像头针脚可以不接(悬空)。

    3.程序编写

    OV7670,Arduino暂无人编写库。所以我们的程序需要带有驱动功能,即具有库的功能。

    兔子我找了某宝的OV7670模块的卖家,他们提供的是STM32的库。我已经移植到Arduino UNO上。

    后续有机会,兔子我再把它调整为库程序,大家就可以直接调用了。

    不废话了,上代码。(由于是驱动程序,有很多操作实际上是对OV7670寄存器的操作,不具有逻辑上的意义)。所以写库就是一件枯燥的事情。必须看厂家的芯片手册你才知道有些操作具有什么含义。

    /*
    

    驱动程序的大概流程是

    1)初始化Arduino的所有IO口。

    2)硬件复位OV7670模块

    3)检测和模块之间的I2C通信,并通过I2C接口配置模块。(即对模块进行初始化,比如配置模块为彩色数据而非黑白,分辨率为320*240等)。

    4)开启中断,等待摄像头1帧数据的开始。第一帧数据放弃,仅用来对齐FIFO的地址。第二帧数据开始,打开FIFO,将摄像头拍摄的数据取出并通过串口上传到电脑。

    5)程序结束

    4.效果

    先放上视频

    f39e5263294de48910e88e1e80cd7162.png
    Arduino UNO 摄像头OV7670效果https://www.zhihu.com/video/1109978486093078528
    实际上,图片拍的不好,有些地方出现噪点及图片错位等问题。
    兔子估计可能是接的杜邦线太长以及接触不良,信号速度又比较快,相互之间有干扰导致。如果直接使用PCB板走线而不是用杜邦线接线,效果会好很多。
    兔子我也是拍了好几次,才有几幅看起来比较OK的图片。

    5.操作流程

    我们Arduino程序,最终目的是将图像数据通过串口传输到电脑上显示。这就需要我们电脑上有对应的软件。

    兔子我找了很久,找到一款名叫"山外多功能调试助手的软件"。

    首先,我们打开它。

    4e4f5b478b31141fe8066b871ed41611.png

    将Arduino UNO板卡通过USB数据线插到我们电脑上。

    e55ca1fdd0c039e4d52b26a2dac66a11.png

    1)选择智能车助手

    2)串口配置,端口选择下拉框里的唯一的一个接口。(接上Arduino板卡后,会自动显示端口号。不插Arduino板卡则不会显示)

    波特率调整为256000

    数据位为8

    校验无

    停止位为1

    3)选择为摄像头

    4)图片配置为彩色图像,设置宽和高分别为320,240。RGB565小端显示。

    5)最后点击 打开串口。

    Arduino板卡就会开始自动上传数据,等待大约10秒,图片就显示在软件的右侧。

    00b45c8e3c28c1b43ed99a50e5ac858a.png
    Arduino UNO 摄像头驱动显示

    如果想再次刷新图片,点击软件的关闭串口按钮。再点击打开串口。等待10秒左右,新的图片就会覆盖旧图片。

    6.资料

    在介绍OV7670之前先附上模块链接:点击购买OV7670摄像头模块
    介绍代码前,首先来看之前写的文章:
    OV7670 FIFO 30W摄像头介绍(一) — 整体介绍/SCCB时序
    OV7670 FIFO 30W摄像头介绍(二) — 寄存器图示说明
    OV7670 FIFO 30W摄像头介绍(三) — STM32F103驱动OV7670代码介绍

    1.OV7670驱动跟上位机通信格式

    目前上位机跟开发板是通过串口来通信,命令通信格式是json,摄像头数据是自定义格式,如果你没听过json,那么自行百度,跟OV7670相关的json格式分别如下:
    在这里插入图片描述
    包含:摄像头开启,摄像头关闭,设置亮度模式,设置饱和度,设置对比度,设置亮度,设置摄像头效果。
    发送格式示例如下(以摄像头开启为例):

    {"FUNC":"HW","OPERATE":"CAMERA_START","PARAM1":null,"PARAM2":null,"PARAM3":null,"PARAM4":null,"PARAM5":null,"PARAM6":null}
    

    1)上位机json发送代码:

    上位机用的c# winform,用的json库using Newtonsoft.Json,此库需要Newtonsoft.Json.dll库,发送代码如下:

    private void json_construction_send(string func,string operate,string param1,string param2,string param3,string param4,string param5,string param6)
    {
        json_commmand cmd = new json_commmand();
        cmd.FUNC = func;
        cmd.OPERATE = operate;
        cmd.PARAM1 = param1;
        cmd.PARAM2 = param2;
        cmd.PARAM3 = param3;
        cmd.PARAM4 = param4;
        cmd.PARAM5 = param5;
        cmd.PARAM6 = param6;
        string json_cmd = JsonConvert.SerializeObject(cmd);
    #if  CONSOLE_DEBUG
        Console.WriteLine(json_cmd);
    #endif
        if (serialPort1.IsOpen)
        {
            serialPort1.WriteLine(json_cmd);
        }
    }
    
    

    其中ov7670的operate字符串包括:

    string operate_camera_start = "CAMERA_START";
    string operate_camera_stop = "CAMERA_STOP";
    string operate_camera_light_mode = "CAMERA_LIGHT";
    string operate_camera_saturation = "CAMERA_SATURATION";
    string operate_camera_brightness = "CAMERA_BRIGHTNESS";
    string operate_camera_contrast = "CAMERA_CONTRAST";
    string operate_camera_effect = "CAMERA_EFFECT";
    

    2)单片机json接收解析代码

    
    
    uint8_t uart_receive_parse(uint8_t *shell_string)
    {
        uint8_t result = HW_ERR_OK;
        cJSON* parse_json = cJSON_Parse((const char *)shell_string);
        uint8_t* func_value = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"FUNC"))->valuestring;
        uint8_t* operate_value = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"OPERATE"))->valuestring;
        uint8_t* para1 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM1"))->valuestring;
        uint8_t* para2 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM2"))->valuestring;
        uint8_t* para3 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM3"))->valuestring;
        uint8_t* para4 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM4"))->valuestring;
        uint8_t* para5 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM5"))->valuestring;
        uint8_t* para6 = (uint8_t*)((cJSON *)cJSON_GetObjectItem(parse_json,"PARAM6"))->valuestring;
    
        if(hw_strcmp((const char *)func_value,"HW") == 0)
        {
            if(hw_strcmp((const char *)operate_value,"CAMERA_START") == 0)
            {
                /* 开启摄像头 */
                goto exit;
            }
    
            if(hw_strcmp((const char *)operate_value,"CAMERA_STOP") == 0)
            {
                /* 关闭摄像头 */
                goto exit;
            }
    
            if(hw_strcmp((const char *)operate_value,"CAMERA_LIGHT") == 0)
            {
                /* 设置摄像头亮度模式 */
                goto exit;
            }
    
            if(hw_strcmp((const char *)operate_value,"CAMERA_SATURATION") == 0)
            {
                /* 设置摄像头饱和度 */
                goto exit;
            }
    
            if(hw_strcmp((const char *)operate_value,"CAMERA_BRIGHTNESS") == 0)
            {
                /* 设置摄像头亮度 */
                goto exit;
            }
    
            if(hw_strcmp((const char *)operate_value,"CAMERA_CONTRAST") == 0)
            {
                /* 设置摄像头对比度 */
                goto exit;
            }
    
            if(hw_strcmp((const char *)operate_value,"CAMERA_EFFECT") == 0)
            {
                /* 设置摄像头效果 */
                goto exit;
            }
            result = HW_ERR_SHELL_NO_CMD;
        }
    
    	if(hw_strcmp((const char *)shell_string,"shop220811498.taobao.com") == 0)
    		HW_DEBUG("welcome to use our stm32f1 camera wifi board\n");
    	else
    		HW_DEBUG("UART PARSE ERR:HW_ERR_SHELL_NO_CMD\n");
    	
        result = HW_ERR_SHELL_NO_CMD;
    exit:
        cJSON_Delete(parse_json);
        return result;
    }

    {
        if (serialPort1.IsOpen)
        {
            try

                string recv_data_string;
                int recv_data_count = serialPort1.BytesToRead;
                while (serialPort1.BytesToRead > 0)
                {
                    recv_data_string = serialPort1.ReadLine();
                    if (recv_data_string.StartsWith("CAML"))
                    {
                        if (recv_data_string.Length >= (320*2*2+4))
                        {
                            Color[] colors;
                            colors = RGBToBitmap(recv_data_string.Substring(4, 1280));

    买了个便宜的摄像头,留着做图像识别。

    今天一用,直接就被泼了一盆凉水。

    UNO资源太少,无法流传输,不如用树莓派,但是用了树莓派,usb接口的不香吗?还有个树莓派专用,这玩意还是排线接口,看32驱动成功的,图像惨不忍睹,还做识别。。

    那就玩玩传个JPG总行吧 ,发现库基本没有。。
