本帖最后由 wdshuang09 于 2017-12-11 21:39 编辑 芯片是STM32F103C8T6移值官方的USBHID,在主函数里调用:USB_SIL_Write(EP1_IN, (uint8_t*) data, 2); SetEPTxValid(ENDP1); 可以将数据发送出去,但改成发送数据长度不4就会出错 USB_SIL_Write(EP1_IN, (uint8_t*) data, 4); SetEPTxValid(ENDP1); 提示:babble detected,是不是发送数据长度超了,应该怎么修改呀,需要修改哪几个点,请高手指点, /* USB Configuration Descriptor */ /* All Descriptors (Configuration, Interface, Endpoint, Class, Vendor */ const uint8_t CustomHID_ConfigDescriptor[CUSTOMHID_SIZ_CONFIG_DESC] = { 0x09, /* bLength: Configuration Descriptor size */ USB_CONFIGURATION_DESCRIPTOR_TYPE, /* bDescriptorType: Configuration */ CUSTOMHID_SIZ_CONFIG_DESC, /* wTotalLength: Bytes returned */ 0x00, 0x01, /* bNumInterfaces: 1 interface */ 0x01, /* bConfigurationValue: Configuration value */ 0x00, /* iConfiguration: Index of string descriptor describing the configuration*/ 0xC0, /* bmAttributes: Bus powered */ 0x32, /* MaxPower 100 mA: this current is used for detecting Vbus */ /************** Descriptor of Custom HID interface ****************/ /* 09 */ 0x09, /* bLength: Interface Descriptor size */ USB_INTERFACE_DESCRIPTOR_TYPE,/* bDescriptorType: Interface descriptor type */ 0x00, /* bInterfaceNumber: Number of Interface */ 0x00, /* bAlternateSetting: Alternate setting */ 0x02, /* bNumEndpoints */ 0x03, /* bInterfaceClass: HID */ 0x00, /* bInterfaceSubClass : 1=BOOT, 0=no boot */ 0x00, /* nInterfaceProtocol : 0=none, 1=keyboard, 2=mouse */ 0, /* iInterface: Index of string descriptor */ /******************** Descriptor of Custom HID HID ********************/ /* 18 */ 0x09, /* bLength: HID Descriptor size */ HID_DESCRIPTOR_TYPE, /* bDescriptorType: HID */ 0x10, /* bcdHID: HID Class Spec release number */ 0x01, 0x00, /* bCountryCode: Hardware target country */ 0x01, /* bNumDescriptors: Number of HID class descriptors to follow */ 0x22, /* bDescriptorType */ CUSTOMHID_SIZ_REPORT_DESC,/* wItemLength: Total length of Report descriptor */ 0x00, /******************** Descriptor of Custom HID endpoints ******************/ /* 27 */ 0x07, /* bLength: Endpoint Descriptor size */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType: */ 0x81, /* bEndpointAddress: Endpoint Address (IN) */ 0x03, /* bmAttributes: Interrupt endpoint */ 0x02, /* wMaxPacketSize: 2 Bytes max */ 0x00, 0x20, /* bInterval: Polling Interval (32 ms) */ /* 34 */ 0x07, /* bLength: Endpoint Descriptor size */ USB_ENDPOINT_DESCRIPTOR_TYPE, /* bDescriptorType: */ /* Endpoint descriptor type */ 0x01, /* bEndpointAddress: */ /* Endpoint Address (OUT) */ 0x03, /* bmAttributes: Interrupt endpoint */ 0x02, /* wMaxPacketSize: 2 Bytes max */ 0x00, 0x20, /* bInterval: Polling Interval (20 ms) */ /* 41 */ } ;
