STM32 USB主机+HID摇杆

【中文标题】STM32 USB主机+HID摇杆【英文标题】：STM32 USB Host + HID Joystick 【发布时间】：2022-01-23 18:48:07 【问题描述】：USB HID 操纵杆连接到我的基于 STM32F401 的开发板。我使用了最新版本的 CubeMX、USB_HOST 库和 HAL。一切都可以使用鼠标和键盘自动运行，但不能使用操纵杆。我根据 USBlyzer 数据在库中做了如下改动：
-
usbh_conf.h
/*---------- -----------*/
#define USBH_MAX_NUM_ENDPOINTS 1U
/*---------- -----------*/
#define USBH_MAX_NUM_INTERFACES 1U
-
usbh_core.c
我在创建 IN 管道时注释掉了代码的所有部分
phost->gState = HOST_ENUMERATION;
phost->Control.pipe_out = USBH_AllocPipe(phost, 0x00U);
// phost->Control.pipe_in = USBH_AllocPipe(phost, 0x80U);
/* Open Control pipes */
// USBH_OpenPipe(phost, phost->Control.pipe_in, 0x80U,
// phost->device.address, phost->device.speed,
// USBH_EP_CONTROL, (uint16_t)phost->Control.pipe_size);
/* Open Control pipes */
USBH_OpenPipe(phost, phost->Control.pipe_out, 0x00U,
phost->device.address, phost->device.speed,
USBH_EP_CONTROL, (uint16_t)phost->Control.pipe_size);
-
usbh_hid.h
为我的操纵杆添加非启动代码
/* Interface Descriptor field values for HID Boot Protocol */
#define HID_BOOT_CODE 0x01U
#define HID_NONE_BOOT_CODE 0x00U
#define HID_KEYBRD_BOOT_CODE 0x01U
#define HID_MOUSE_BOOT_CODE 0x02U
-
usbh_hid.c
添加
else if (phost->device.CfgDesc.Itf_Desc[interface].bInterfaceProtocol == HID_NONE_BOOT_CODE)
USBH_UsrLog("Non boot device found!");
将协议更改为非启动
case HID_REQ_SET_PROTOCOL:
/* set protocol */
classReqStatus = USBH_HID_SetProtocol(phost, 1U);
if (classReqStatus == USBH_OK)
HID_Handle->ctl_state = HID_REQ_IDLE;
我的代码在USB_HID_ClassRequest 函数中获取USB_HID_GetHIDReportDescriptor 并得到它。但随后它在USB_HID_Process 中的USB_HID_GetReport 函数上发生故障，我总是得到USB_NOT_SUPPORTED 的状态。我需要获取报告，我的函数会处理数据，但我无法获取报告并且真的不明白为什么。
因此，我需要你的帮助，也许有人已经使用过类似的 HID 设备和 USB_HOST 库。
