STM32 USB Host + HID Joystick

原文 2021-12-22 14:45:36 9 0 c/ usb/ stm32/ hid/ joystick

A USB HID Joystick is connected to my STM32F401-based board. I used last versions CubeMX, the USB_HOST library, and HAL. Everything works automatically with the mouse and keyboard, but not with the joystick. I made the following changes in the library based on USBlyzer data:

usbh_conf.h

/*----------   -----------*/
#define USBH_MAX_NUM_ENDPOINTS      1U

/*----------   -----------*/
#define USBH_MAX_NUM_INTERFACES      1U

usbh_core.c

I commented out all sections of the code with the creation of the IN pipe

  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

Add nonboot code for my joystick

/* 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

Add

  else if (phost->device.CfgDesc.Itf_Desc[interface].bInterfaceProtocol  == HID_NONE_BOOT_CODE)
  {
    USBH_UsrLog("Non boot device found!");
  }

Changed the protocol to non-boot

case HID_REQ_SET_PROTOCOL:
    /* set protocol */
    classReqStatus = USBH_HID_SetProtocol(phost, 1U);
    if (classReqStatus == USBH_OK)
    {
      HID_Handle->ctl_state = HID_REQ_IDLE;

My code goes as far as getting the USB_HID_GetHIDReportDescriptor in the USB_HID_ClassRequest function and gets it. But then it breaks down on the USB_HID_GetReport function in USB_HID_Process , where I always get the status USB_NOT_SUPPORTED . I need to get a report, my functions will process the data, but I can't get a report and really don't understand why.

Therefore, I need your help, maybe someone has already worked with similar HID devices and USB_HOST library.
