使用开发板为正点原子ministm32

现在我们先使用HID descriptor Tool来生成我们需要的hid的

保存使用选择.H

  1. // D:\usb资料\HID\MSDEV\Projects\test\Desc_HID.h
  2.  
  3. char ReportDescriptor[] = {
  4.     0x06, 0x00, 0xff,              // USAGE_PAGE (Vendor Defined Page 1)
  5.     0x09, 0x01,                    // USAGE (Vendor Usage 1)
  6.     0xa1, 0x01,                    // COLLECTION (Application)
  7.     0x09, 0x01,                    //   USAGE (Vendor Usage 1)
  8.     0x15, 0x00,                    //   LOGICAL_MINIMUM (0)
  9.     0x26, 0xff, 0x00,              //   LOGICAL_MAXIMUM (255)
  10.     0x95, 0x40,                    //   REPORT_COUNT (64)
  11.     0x75, 0x08,                    //   REPORT_SIZE (8)
  12.     0x81, 0x02,                    //   INPUT (Data,Var,Abs)
  13.     0x09, 0x01,                    // USAGE (Vendor Usage 1)
  14.     0x15, 0x00,                    // LOGICAL_MINIMUM (0)
  15.     0x26, 0xff, 0x00,              // LOGICAL_MAXIMUM (255)
  16.     0x95, 0x40,                    // REPORT_COUNT (64)

  18.     0x91, 0x02,                    // OUTPUT (Data,Var,Abs)
  19.     0xc0                           // END_COLLECTION
  20. };

现在使用使用STM32CubeMX来生成我们的工程

将char ReportDescriptor[34] 修改工程中CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE]

  1. /** @defgroup USBD_AUDIO_IF_Private_Variables
  2.  * @{

  4. __ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALIGN_END =
  5. {
  6.   /* USER CODE BEGIN 0 */
  7.     0x06, 0x00, 0xff,              // USAGE_PAGE (Vendor Defined Page 1)

现在编译下载测试

先使用USBlyzer来看看

现在继续修改我们代码增加发送PC数据

现在修改一下工程代码

注释掉main.C中的

好了测试一下

 存在一个问题当PC发送不是64位时怎么处理？？未解决

后面找到一些资料: 所有的 HID 数据都必须使用定义过的报表格式来定义报表中数据的大小与内容。设备可
以支持一个或多个报表。在固件中的报表描述符用来描述了此报表，以及如何使用报表数据的
