DE2 board USB communication

Hi,

I’m modifying the firmware coding of device controller which found from DE2 CD.

My target is to send 16 bytes data block per transmission.

I had modify the coding from ISR.c and mainloop.c

But I still fail to make it transfer 16 bytes data per packet.

(this is the coding from interrupt service routine,ISR.c)

void Isr_Ep02Done(void)

{

unsigned char bbuf[16];

int i = 0;

Hal4D13_GetEndpointStatusWInteruptClear(EPINDEX4EP02);

Hal4D13_ReadEndpoint(EPINDEX4EP02,&bbuf, 16); //error was found here : passing arg 2 of //'hal4d13_readendpoint' from incompatible pointer type.

if( sendCount < length)

{

Hal4D13_WriteEndpoint(EPINDEX4EP02, data + sendCount, 16);

Hal4D13_GetEndpointStatusWInteruptClear(EPINDEX4EP02);

sendCount += 16;

if(sendCount > length)

{

sendCount = 0;

length = 0;

for( i = 0; i < 65; i++)

data[i] = 0;

}

}

}

Can anyone give me suggestion on how can I debug this error? I’m stuck….

Thanks,

Summer
