usb hid STM32可以发出，就是收不到数据

liuyu0624 · 发表于 2016-2-24 13:24:37

程序是原子例程的触控鼠标改的，就修改了下描述文件。把LCD显示去掉。
改完之后PC上位机可以收到下位机发出的数据，可是上位机不能发给你下位机
上位机软件上点发送，显示发出数据字节数为-1，这点很不解，什么意思呢。

找到原因了··········
void Joystick_Reset(void)
{
  /* Set Joystick_DEVICE as not configured */
  pInformation->Current_Configuration = 0;
  pInformation->Current_Interface = 0;/*the default Interface*/

  /* Current Feature initialization */
  pInformation->Current_Feature = Joystick_ConfigDescriptor[7];
  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);
  SetEPRxAddr(ENDP1, ENDP1_RXADDR);
  SetEPTxCount(ENDP1, 64);
  SetEPRxCount(ENDP1, 64);
  SetEPRxStatus(ENDP1, EP_RX_VALID);
  SetEPTxStatus(ENDP1, EP_TX_NAK);


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

原本这个函数里面未使能接收···········。
