Posted on March 12, 2015 at 10:34this topic is very usefull.
i got another question. I'm using the same ic STM32F105, and i used STM32F103 before.
I want to output more than 64 byte data in to MPU in sereval time, but the data is in same part.
the code below:
void EP1_OUT_Callback(void)
{
__IO uint16_t wEPVal = 0;
u32 volatile n;
PMAToUserBufferCopy(&USB_Receive_Buffer[USB_Receive_Length], ENDP1_RXADDR, REPORT_COUNT);
USB_Receive_Length += 64;
SetEPRxStatus(ENDP1, EP_RX_VALID);
// wait for the interrupt
n = 5333 * 5;
while(n--);
// check if this is the last packet
wIstr = _GetISTR();
if((wIstr & ISTR_CTR) == 0)
{
USB_Received_Flag = 1;
}
}
but now i can't find USB_ISTR register now, how can i access the H/W Flag to check ISTR?
