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
// D:\usb资料\HID\MSDEV\Projects\test\Desc_HID.h
char ReportDescriptor[] = {
0x06, 0x00, 0xff, // USAGE_PAGE (Vendor Defined Page 1)
0x09, 0x01, // USAGE (Vendor Usage 1)
0xa1, 0x01, // COLLECTION (Application)
0x09, 0x01, // USAGE (Vendor Usage 1)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255)
0x95, 0x40, // REPORT_COUNT (64)
0x75, 0x08, // REPORT_SIZE (8)
0x81, 0x02, // INPUT (Data,Var,Abs)
0x09, 0x01, // USAGE (Vendor Usage 1)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255)
0x95, 0x40, // REPORT_COUNT (64)
0x75, 0x08, // REPORT_SIZE (8)
0x91, 0x02, // OUTPUT (Data,Var,Abs)
0xc0 // END_COLLECTION
};
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]
/** @defgroup USBD_AUDIO_IF_Private_Variables
* @{
*/
__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALIGN_END =
{
/* USER CODE BEGIN 0 */

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

可以看到下面的数据在变化
bus hound的设置如下
现在使用bus hound发送数据到MCU
现在修改一下工程代码
注释掉main.C中的
// USBD_CUSTOM_HID_SendReport(&hUsbDeviceFS, &send_buf[0],64);
// send_buf[0]++;
// HAL_Delay(2000);

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
信息。
