前沿??

????????前面两节主要是对USB的基本概念做了简单讲解，学习USB的最本质目的还是要回到USB的应用方向，接下来的几章主要讲解USB的各类应用，包括：

????????这里只讲怎么修改描述符和关键函数，具体含义请参考Video参考手册，我们这里使用《Audio_Speaker》例程进行修改。

1 描述符修改

????????usb_desc.h文件的描述符宏定义如下：

    0x81,                               /* IN endpoint 1 */
    0x01,                               /* Isochronous transfer type. Asynchronous synchronization type. */
    MAKE_WORD(PACKET_SIZE),             /* Max packet size, in bytes */
    0x01,                               /* One frame interval */
    /* 7 bytes, total size 144 */
};

1.3 字符串描述符修改

????????这里只需要修改StringProduct字符串描述符，修改名称为microphone。

const uint8_t Speaker_StringProduct[SPEAKER_SIZ_STRING_PRODUCT] =
  {
    SPEAKER_SIZ_STRING_PRODUCT,  /* bLength */
    USB_STRING_DESCRIPTOR_TYPE,        /* bDescriptorType */
    'S', 0, 'T', 0, 'M', 0, '3', 0, '2', 0, ' ', 0,
    'C', 0, 'a', 0, 'm', 0, 'e', 0, 'r', 0, 'a', 0
  };

1.4 编译报错修改

? ? ? ? 发现修改了这些位置，会出现报错，我们继续修改，主要修改以下文件：

  • usb_desc.c
  • usb_desc.h
  • usb_prop.c

? ? ? ? 按照下图修改。

? ? ? ? 按照上图修改完成，在设备管理器会出现STM32 Camera的设备，证明修改成功，如果修改之后设备管理器没有反应，大概率是D+的上拉电阻没有配对。

2 增加功能函数

2.1 Camera功能模块介绍

? ? ? ? 由于STM32F103系列没有DCMI外设，如果使用GPIO模拟DCMI时序去读取摄像头数据会显得很卡顿，所以这里仅展示单张图片的显示。

2.2 USB复位函数修改

/*******************************************************************************

* Description    : Speaker reset routine.
* Input          : None.
* Output         : None.

*******************************************************************************/
void Speaker_Reset()
{
    /* Set Camera device as not configured state */
    pInformation->Current_Configuration = 0;
 
    /* Current Feature initialization */
    pInformation->Current_Feature = Speaker_ConfigDescriptor[7];
 
    SetBTABLE(BTABLE_ADDRESS);
 
    /* Initialize Endpoint 0 */
    SetEPType(ENDP0, EP_CONTROL);
    SetEPTxStatus(ENDP0, EP_TX_NAK);
    SetEPRxAddr(ENDP0, ENDP0_RXADDR);
    SetEPRxCount(ENDP0, Device_Property.MaxPacketSize);
    SetEPTxAddr(ENDP0, ENDP0_TXADDR);
    Clear_Status_Out(ENDP0);
    SetEPRxValid(ENDP0);
 
    /* Initialize Endpoint 1 */
    SetEPType(ENDP1, EP_ISOCHRONOUS);
    SetEPDblBuffAddr(ENDP1, ENDP1_BUF0Addr, ENDP1_BUF1Addr);
    SetEPDblBuffCount(ENDP1, EP_DBUF_OUT, PACKET_SIZE);
    ClearDTOG_RX(ENDP1);
    ClearDTOG_TX(ENDP1);
    ToggleDTOG_RX(ENDP1);
    SetEPRxStatus(ENDP1, EP_RX_DIS);
    SetEPTxStatus(ENDP1, EP_TX_VALID);
 
    SetEPRxValid(ENDP0);
    /* Set this device to response on default address */
    SetDeviceAddress(0);
 
    bDeviceState = ATTACHED;
}

2.3?Speaker_Data_Setup函数修改

? ? ? ? 增加此函数主要是打开摄像头软件的时候，会请求一些图像的参数，比如像谁，时钟频率等。

2.4 非零端点函数修改

? ? ? ? 因为这个是Microphone，是同步In传输，所以需要屏蔽OUT函数（usb_endp.c文件中），并增加In函数。

? ? ? ? jpeg_data数组是单帧JPEG图片数据。

#include "usb_desc.h"
#include <string.h>

#define JPEG_SIZE  10000

const unsigned char jpeg_data[JPEG_SIZE] = {

2.5 JEPG数据获取

? ? ? ? 获取JPEG图片数据的方法比较简单，方法如下：

1. 网上下载一张JPG格式的图片，如果下载不到，可以使用在线图片转换器进行图片格式的转换；

2. 使用《画图》工具调整图片的尺寸为320*240像素；

3. 使用《winhex》工具，把图片转换成8位的数组。

4. 创建txt文档，把刚才复制的数据粘贴出来。

const unsigned char jpeg_data[JPEG_SIZE] = {
	0xFF, 0xD8, 0xFF, 0xE0, 0x00, 0x10, 0x4A, 0x46, 0x49, 0x46, 0x00, 0x01, 0x01, 0x01, 0x00, 0x60,

3 运行演示

1. 正确下载程序，能够在设备管理器查看到Camera设备。

2. 打开系统自带的照相机软件，显示如下图。

3. 逻辑分析仪抓取波形如下，同步传输没有ACK包。

接下来讲解STM32 USB 复合设备传输通信实验，敬请期待。。。
