1. 修改usb_conf.h文件

#define EP_NUM (3) 改为3个端点

#define ENDP2_RXADDR (0x128) 分配端点2输出ram偏移

/* #define EP1_IN_Callback NOP_Process*/

#define EP2_IN_Callback NOP_Process

#define EP3_IN_Callback NOP_Process

#define EP4_IN_Callback NOP_Process

#define EP5_IN_Callback NOP_Process

#define EP6_IN_Callback NOP_Process

#define EP7_IN_Callback NOP_Process

#define EP1_OUT_Callback NOP_Process

//#define EP2_OUT_Callback NOP_Process

#define EP3_OUT_Callback NOP_Process

#define EP4_OUT_Callback NOP_Process

#define EP5_OUT_Callback NOP_Process

#define EP6_OUT_Callback NOP_Process

#define EP7_OUT_Callback NOP_Process

允许端点1输入回调，允许端点2输出回调处理

2. 在main.c文件或usb_endp.c中定义回调函数

voidEP2_OUT_Callback(void)

{

USB_ReceiveFlg = TRUE;

PMAToUserBufferCopy(Receive_Buffer,ENDP2_RXADDR,16);

MsgCmd =Receive_Buffer[0];

switch(MsgCmd)

{

case 1:

LED1_ON;

break;

case 2:

LED2_ON;

break;

default:

LED1_OFF; LED2_OFF;

}

SetEPRxStatus(ENDP2,EP_RX_VALID);

}

3. 修改VID和PID方便区别

constuint8_t Joystick_DeviceDescriptor[JOYSTICK_SIZ_DEVICE_DESC] =

{

0x12, /*bLength */

USB_DEVICE_DESCRIPTOR_TYPE, /*bDescriptorType*/

0x00, /*bcdUSB*/

0x02,

0x00, /*bDeviceClass*/

0x00, /*bDeviceSubClass*/

0x00, /*bDeviceProtocol*/

0x40, /*bMaxPacketSize 64*/

0x16, /*idVendor (0x0483)*/

0x20,

0x09, /*idProduct = 0x5710*/

0x05,

0x00, /*bcdDevice rel. 2.00*/

0x02,

1, /*Index of string descriptor describing

manufacturer */

2, /*Index of string descriptor describing

product*/

3, /*Index of string descriptor describing the

device serial number */

0x01 /*bNumConfigurations*/

}

4. 修改配置描述符

constuint8_t Joystick_ConfigDescriptor[JOYSTICK_SIZ_CONFIG_DESC] =

{

0x09, /* bLength: Configuration Descriptorsize */

USB_CONFIGURATION_DESCRIPTOR_TYPE, /*bDescriptorType: Configuration */

JOYSTICK_SIZ_CONFIG_DESC,

/* wTotalLength: Bytes returned */

0x00,

0x01, /*bNumInterfaces: 1 interface*/

0x01, /*bConfigurationValue: Configurationvalue*/

0x00, /*iConfiguration: Index of stringdescriptor describing

theconfiguration*/

0xE0, /*bmAttributes: Self powered */

0x32, /*MaxPower 100 mA: this current isused for detecting Vbus*/

/************** Descriptor of JoystickMouse interface ****************/

/* 09 */

0x09, /*bLength: Interface Descriptor size*/

USB_INTERFACE_DESCRIPTOR_TYPE,/*bDescriptorType: Interface descriptortype*/

0x00, /*bInterfaceNumber: Number ofInterface*/

0x00, /*bAlternateSetting: Alternatesetting*/

0x02, /*bNumEndpoints*/ //变为两个端口 ep1 IN ep2 OUT

0x03, /*bInterfaceClass: HID*/

0x00, /*bInterfaceSubClass : 1=BOOT, 0=no boot*/ //自定义hid

0x00, /*nInterfaceProtocol : 0=none, 1=keyboard,2=mouse*/ //自定义hid

0, /*iInterface: Index of stringdescriptor*/

/*********** Descriptor of Joystick MouseHID ********************/

/* 18 */

0x09, /*bLength: HID Descriptor size*/

HID_DESCRIPTOR_TYPE, /*bDescriptorType:HID*/

0x00, /*bcdHID: HID Class Spec releasenumber*/

0x01,

0x00, /*bCountryCode: Hardware target country*/

0x01, /*bNumDescriptors: Number of HID classdescriptors to follow*/

0x22, /*bDescriptorType*/

JOYSTICK_SIZ_REPORT_DESC,/*wItemLength:Total length of Report descriptor*/

0x00,

/************* Descriptor of Joystick Mouseendpoint ********************/

/* 27 */

0x07, /*bLength: Endpoint Descriptor size*/

USB_ENDPOINT_DESCRIPTOR_TYPE,/*bDescriptorType:*/

0x81, /*bEndpointAddress: Endpoint Address(IN)*/

// bit 3...0 : the endpoint number

// bit 6...4 : reserved

// bit 7 : 0(OUT), 1(IN)

0x03, /*bmAttributes: Interrupt endpoint*/

0x04, /*wMaxPacketSize: 4 Byte max */ //包长为4byte

0x00,

0x20, /*bInterval: Polling Interval (32ms)*/

/* 34 */

0x07, /* bLength: Endpoint Descriptor size */

USB_ENDPOINT_DESCRIPTOR_TYPE, /*bDescriptorType: */

/* Endpoint descriptor type */

0x02, /* bEndpointAddress: */ //追加一个端点2作为输出

/* Endpoint Address (OUT) */

0x03, /* bmAttributes: Interrupt endpoint */

0x08,//0x02, /* wMaxPacketSize: 20 Bytes max */ //包长为8byte

0x00,

0x10, /* bInterval: Polling Interval (32 ms)*/

/* 41 */

}

; /* MOUSE_ConfigDescriptor */

别忘了修改JOYSTICK_SIZ_CONFIG_DESC数组的大小为41。

5. 最后修改报告描述符，同样JOYSTICK_SIZ_REPORT_DESC修改为27

constuint8_t Joystick_ReportDescriptor[JOYSTICK_SIZ_REPORT_DESC] =

{

0x05,0x01, // USAGE_PAGE (Generic Desktop)

0x09,0x00, // USAGE (0)

0xa1,0x01, // COLLECTION (Application)

0x15,0x00, // LOGICAL_MINIMUM (0)

0x25,0xff, // LOGICAL_MAXIMUM (255)

0x19,0x01, // USAGE_MINIMUM (1)

0x29,0x08, // USAGE_MAXIMUM (8)

0x95,0x08, // REPORT_COUNT (8)

0x75,0x08, // REPORT_SIZE (8)

0x81,0x02, // INPUT (Data,Var,Abs)

//--------------------------------输出---------------------

0x19,0x01,

0x29,0x08,

0x91,0x02,

0xc0 // END_COLLECTION

}; /* CustomHID_ReportDescriptor */
