关于HID Boot Keyboard的问题？

只看该作者 · 2011-12-28 23:24

我用Cy7C64251做了一个HID键盘，目前问题：不能在bois下工作。windows下没问题。接口描述等等都对照了，没问题。
请问有高手做过键盘吗？请指教，谢谢
附上主程序：
void main(void)
{
int temp,i;

M8C_EnableGInt;                      //Enable Global Interrupts
Timer8_1_EnableInt();             // Enable the Timer8 interrupt
Timer8_1_Start();                // Timer8 Start and initialization

USBFS_Start(0, USB_5V_OPERATION);    //Start USBFS Operation using device 0 and with 5V operation
while(!USBFS_bGetConfiguration());    //Wait for Device to enumerate


//Enumeration is completed load endpoint 1. Do not toggle the first time
USBFS_LoadInEP(1, keycode, 8, USB_NO_TOGGLE);
while(!USBFS_bGetEPAckState(1)); //Check and see if ACK has occured
while(!(USBFS_bGetEPState(1) & IN_BUFFER_EMPTY));
USBFS_LoadInEP(1, keycode, 8, USB_TOGGLE);

USBFS_EnableOutEP(2);

while(1)
{



scan();
PRT0DR_BUF&=0xcf;
   PRT0DR=PRT0DR_BUF;
   temp=PRT0DR&0x07;
   if(temp==0x07)
   {
   if(codeflag==1)
   {

   for(i=0;i<8;i++)
{
      keycode[i]=0;
}

if(USBFS_bGetEPAckState(1)) //Wait for ACK before loading data
      {
      USBFS_LoadInEP(1, keycode, 8, USB_TOGGLE);
            }
   for(i=0;i<6;i++)
{
OldInbuf[i]=0;
Inbuf[i]=0;
}
codeflag=0;
   }
}

if(USBFS_bGetEPState(2))
      {
      USBFS_bReadOutEP(2, Buf, 8);
   USBFS_EnableOutEP(2);
      if(Buf[0]&0x02)
      {
      PRT0DR_BUF&=0xf7;
               PRT0DR=PRT0DR_BUF;

      }
      else
      {
               PRT0DR_BUF|=0xcf;
               PRT0DR=PRT0DR_BUF;
      }
   USBFS_EnableOutEP(2);
   Delay(4000);
}
}
}
