这两个设备都是USB HID设备．计算机已经识别出这两种设备，并且自定义的HID设备已经可以操作，只是HID键盘不能操作，键盘所使用的端口收不到数据，打断点不能进来．不知道是那里问题．

复位初始代码如下：
void USB_Reader_Reset(void)
{
/* Set USB_Reader_DEVICE as not configured */
pInformation->Current_Configuration = 0;
pInformation->Current_Interface = 0;/*the default Interface*/
SetBTABLE(BTABLE_ADDRESS);
/* Initialize Endpoint 0 */
SetEPType(ENDP0, EP_CONTROL);
SetEPTxStatus(ENDP0, EP_TX_STALL);
SetEPRxAddr(ENDP0, ENDP0_RXADDR);
SetEPTxAddr(ENDP0, ENDP0_TXADDR);
Clear_Status_Out(ENDP0);
SetEPRxCount(ENDP0, Device_Property.MaxPacketSize);
SetEPRxValid(ENDP0);
/* Initialize Endpoint 1 */
SetEPType(ENDP1, EP_INTERRUPT);
SetEPTxAddr(ENDP1, ENDP1_TXADDR);
SetEPTxCount(ENDP1, REC_BUFFER_SIZE);
SetEPRxStatus(ENDP1, EP_RX_DIS);
SetEPTxStatus(ENDP1, EP_TX_NAK);
/* Initialize Endpoint 1 */
// SetEPType(ENDP1, EP_INTERRUPT);
SetEPRxAddr(ENDP1, ENDP1_RXADDR);
SetEPRxCount(ENDP1, REC_BUFFER_SIZE);
// SetEPTxStatus(ENDP1, EP_TX_DIS);
SetEPRxStatus(ENDP1, EP_RX_VALID);
// Initialize Endpoint 3
SetEPType(ENDP3, EP_INTERRUPT);
SetEPTxAddr(ENDP3, ENDP3_TXADDR);
SetEPTxCount(ENDP3, 0x20);
SetEPRxStatus(ENDP3, EP_RX_DIS);
SetEPTxStatus(ENDP3, EP_TX_NAK);
SetEPRxAddr(ENDP3, ENDP3_RXADDR);
SetEPRxCount(ENDP3, 0x20);
SetEPRxStatus(ENDP3, EP_RX_VALID);
/* Set this device to response on default address */
SetDeviceAddress(0);
}
键盘底层发送函数是这样的:
void USB_NumKey_SendMsg(u8 buffer[],u8 len)
{
u8 USB_Buffer[REC_BUFFER_SIZE];
u8 i;
if(len>REC_BUFFER_SIZE) len=REC_BUFFER_SIZE;
for(i=0;i<len;i++)
{
USB_Buffer= buffer;
}
for(i=len;i<0x20;i++)
{
USB_Buffer= 0;
}
/*copy buffer in ENDP1 Tx Packet Memory Area*/
UserToPMABufferCopy(USB_Buffer, GetEPTxAddr(ENDP3), 0x20);
SetEPTxCount(ENDP3, 0x08);
/* enable endpoint for transmission */
SetEPTxValid(ENDP3);
}
键码发送函数，如下：
/*******************************************************************************
* Function Name : Sent_Key_Code
* Description : 发送键码
* Input : buffer:键码缓存
* Len:缓存长度
* Output : None.
* Return : None.
*******************************************************************************/
void Sent_Key_Code(u8 *buffer,u8 len)
{
u8 i;
u32 iTemp;
u8 keycode[12];
u8 InBuffer[32];
iTemp = 0;
for(i=0;i<len;i++)
iTemp = (iTemp<<8)|buffer; //0x2C9AF666
keycode[0] = iTemp/1000000000; //最高位
keycode[1] = (iTemp%1000000000)/100000000;
keycode[2] = (iTemp%100000000)/10000000;
keycode[3] = (iTemp%10000000)/1000000;
keycode[4] = (iTemp%1000000)/100000;
keycode[5] = (iTemp%100000)/10000;
keycode[6] = (iTemp%10000)/1000;
keycode[7] = (iTemp%1000)/100;
keycode[8] = (iTemp%100)/10;
keycode[9] = (iTemp%10)/1;
for(i=0;i<10;i++)
if(keycode==0)
keycode = 0x62; //0x62为0的键码值
else
keycode = keycode + 0x58; //0x59为1的键码值
//按键缓存第一字节为控制码,这里赋值为0
//按键缓存第二字节为保留,
for(i=0;i<8;i++)
InBuffer = 0;
for(i=2;i<8;i++)
InBuffer = keycode[i-2]; //卡号的前6字节，已转换为10进制
USB_NumKey_SendMsg(InBuffer,8); //发送键码值,
}
请各位高手帮忙解答，谢谢． |
