为了去掉感叹号需要实现每个端点的功能
首先是 ENDP0 控制端点
这个端点 的功能在 USBprop.c里面
主要是一大把函数指针
这是CDC下的
DEVICE_PROP Device_Property =
{
Virtual_Com_Port_init,
Virtual_Com_Port_Reset,
Virtual_Com_Port_Status_In,
Virtual_Com_Port_Status_Out,
Virtual_Com_Port_Data_Setup,
Virtual_Com_Port_NoData_Setup,
Virtual_Com_Port_Get_Interface_Setting,
Virtual_Com_Port_GetDeviceDescriptor,
Virtual_Com_Port_GetConfigDescriptor,
Virtual_Com_Port_GetStringDescriptor,
0,
0x40 /*MAX PACKET SIZE*/
};这是MassStroage下的
DEVICE_PROP Device_Property =
{
MASS_init,
MASS_Reset,
MASS_Status_In,
MASS_Status_Out,
MASS_Data_Setup,
MASS_NoData_Setup,
MASS_Get_Interface_Setting,
MASS_GetDeviceDescriptor,
MASS_GetConfigDescriptor,
MASS_GetStringDescriptor,
0,
0x40 /*MAX PACKET SIZE*/
};
可以看到这一部分都是一样的 我们修改时改个名字即可
DEVICE_PROP Device_Property =
{
Composite_init,
Composite_Reset,
Composite_Status_In,
Composite_Status_Out,
Composite_Data_Setup,
Composite_NoData_Setup,
Composite_Get_Interface_Setting,
Composite_GetDeviceDescriptor,
Composite_GetConfigDescriptor,
Composite_GetStringDescriptor,
0,
0x40 /*MAX PACKET SIZE*/
};
下一个函数指针组也是一样的，改个名字就好了
CDC
USER_STANDARD_REQUESTS User_Standard_Requests =
{
Virtual_Com_Port_GetConfiguration,
Virtual_Com_Port_SetConfiguration,
Virtual_Com_Port_GetInterface,
Virtual_Com_Port_SetInterface,
Virtual_Com_Port_GetStatus,
Virtual_Com_Port_ClearFeature,
Virtual_Com_Port_SetEndPointFeature,
Virtual_Com_Port_SetDeviceFeature,
Virtual_Com_Port_SetDeviceAddress
};
MassStroage
USER_STANDARD_REQUESTS User_Standard_Requests =
{
Mass_Storage_GetConfiguration,
Mass_Storage_SetConfiguration,
Mass_Storage_GetInterface,
Mass_Storage_SetInterface,
Mass_Storage_GetStatus,
Mass_Storage_ClearFeature,
Mass_Storage_SetEndPointFeature,
Mass_Storage_SetDeviceFeature,
Mass_Storage_SetDeviceAddress
};
如下
USER_STANDARD_REQUESTS User_Standard_Requests =
{
Composite_GetConfiguration,
Composite_SetConfiguration,
Composite_GetInterface,
Composite_SetInterface,
Composite_GetStatus,
Composite_ClearFeature,
Composite_SetEndPointFeature,
Composite_SetDeviceFeature,
Composite_SetDeviceAddress
};
可以看到这些函数指针都是一样的，但是CDC和Mass的函数实现不同，我们需要把它们和到一起。
首先去看usbprop.h
可以看到
#define Virtual_Com_Port_GetConfiguration NOP_Process
//#define Virtual_Com_Port_SetConfiguration NOP_Process
#define Virtual_Com_Port_GetInterface NOP_Process
#define Virtual_Com_Port_SetInterface NOP_Process
#define Virtual_Com_Port_GetStatus NOP_Process
#define Virtual_Com_Port_ClearFeature NOP_Process
#define Virtual_Com_Port_SetEndPointFeature NOP_Process
#define Virtual_Com_Port_SetDeviceFeature NOP_Process
//#define Virtual_Com_Port_SetDeviceAddress NOP_Process
CDC只要2函数 其他都为nop
#define Mass_Storage_GetConfiguration NOP_Process
/* #define Mass_Storage_SetConfiguration NOP_Process*/
#define Mass_Storage_GetInterface NOP_Process
#define Mass_Storage_SetInterface NOP_Process
#define Mass_Storage_GetStatus NOP_Process
/* #define Mass_Storage_ClearFeature NOP_Process*/
#define Mass_Storage_SetEndPointFeature NOP_Process
#define Mass_Storage_SetDeviceFeature NOP_Process
/*#define Mass_Storage_SetDeviceAddress NOP_Process*/
Mass则实现了3个，其中2个重合
我们先修改注释掉这3个nop
#define Composite_GetConfiguration NOP_Process
//#define Composite_SetConfiguration NOP_Process
#define Composite_GetInterface NOP_Process
#define Composite_SetInterface NOP_Process
#define Composite_GetStatus NOP_Process
//#define Composite_ClearFeature NOP_Process
#define Composite_SetEndPointFeature NOP_Process
#define Composite_SetDeviceFeature NOP_Process
//#define Composite_SetDeviceAddress NOP_Process
然后去看这些函数，主要是看这些函数都做了什么
CDC中

Bot_Abort(BOTH_DIR);
}
/*******************************************************************************

*******************************************************************************/
void Mass_Storage_SetDeviceAddress (void)
{
bDeviceState = ADDRESSED;
}
可以看到 CDC做的Mass都做了，所以直接用Mass的修改下名字即可
/*******************************************************************************

ClearDTOG_TX(ENDP4);
ClearDTOG_RX(ENDP5);
Bot_State = BOT_IDLE; /* set the Bot state machine to the IDLE state */
}
}

{
bDeviceState = ADDRESSED;
}
void Composite_ClearFeature (void)
{

Bot_Abort(BOTH_DIR);
}
下面需要一个一个看init Reset这些函数的实现并且融合
这里以Reset看
/*******************************************************************************

SetEPType(ENDP0, EP_CONTROL);

/* Set this device to response on default address */
SetDeviceAddress(0);
bDeviceState = ATTACHED;
}
/*******************************************************************************

void MASS_Reset()
{

Device_Info.Current_Configuration = 0;

SetDeviceAddress(0);
bDeviceState = ATTACHED;
CBW.dSignature = BOT_CBW_SIGNATURE;
Bot_State = BOT_IDLE;
USB_NotConfigured_LED();
}
我们看到这个两个函数实现由较大的差异
这个函数的功能可以看到是实现可USBEP的初始化，这里我们要按照实际情况写
把Mass的ENDP1，ENDP2 改换为我们配置的 ENDP4 ENDP5 然后叠加到CDC的配置上去，结果就成了这样
/*******************************************************************************

*******************************************************************************/
void Composite_Reset(void)

pInformation->Current_Interface = 0;
SetBTABLE(BTABLE_ADDRESS);
/* Initialize Endpoint 0 */
SetEPType(ENDP0, EP_CONTROL);
SetEPTxStatus(ENDP0, EP_TX_STALL);
SetEPRxAddr(ENDP0, ENDP0_RXADDR);
SetEPTxAddr(ENDP0, ENDP0_TXADDR);

SetEPType(ENDP2, EP_INTERRUPT);
SetEPTxAddr(ENDP2, ENDP2_TXADDR);
SetEPRxStatus(ENDP2, EP_RX_DIS);
SetEPTxStatus(ENDP2, EP_TX_NAK);
/* Initialize Endpoint 3 */
SetEPType(ENDP3, EP_BULK);
SetEPRxAddr(ENDP3, ENDP3_RXADDR);
SetEPRxCount(ENDP3, Composite_DATA_SIZE);
SetEPRxStatus(ENDP3, EP_RX_VALID);
SetEPTxStatus(ENDP3, EP_TX_DIS);
/* Initialize Endpoint 2 IN */
SetEPType(ENDP4, EP_BULK);
SetEPTxCount(ENDP4, 64);
SetEPTxAddr(ENDP4, ENDP4_TXADDR);
SetEPTxStatus(ENDP4, EP_TX_NAK);
SetEPRxStatus(ENDP4, EP_RX_DIS);
/* Initialize Endpoint 2 OUT */
SetEPType(ENDP5, EP_BULK);
SetEPRxAddr(ENDP5, ENDP5_RXADDR);
SetEPRxCount(ENDP5, 64);
SetEPRxStatus(ENDP5, EP_RX_VALID);
SetEPTxStatus(ENDP5, EP_TX_DIS);
/* Set this device to response on default address */
SetDeviceAddress(0);
CBW.dSignature = BOT_CBW_SIGNATURE;
Bot_State = BOT_IDLE;
bDeviceState = ATTACHED;
}
其他函数也是根据实际情况进行修改
最终修改结果如下
