It is showing me Error "USB is unrecognized". Only Transmitting Function is working Properly.
int8_t CDC_Receive_FS_User (uint8_t* Buf, uint32_t *Len)//Non-Static
{
CDC_Receive_FS(Buf,Len);// >> static Funcation( usbd_cdc_if.c )
}
/*
* if I am NOT able to send data on COM port.
* Problems comes When i am trying to receive data from COM port.
* USB is unrecognised. Don't know why ????
*/
uint32_t *Len = (uint32_t *)calloc(1,4);
Len = (uint32_t *)20;
uint8_t Buffer_CDC[20];
if( CDC_Receive_FS_User(Buffer_CDC, (uint32_t *)Len) == USBD_OK )
{
uint16_t length = sizeof(Buffer_CDC);
if(CDC_Transmit_FS( Buffer_CDC, length ) ==USBD_OK )
{
HAL_GPIO_WritePin(GPIOC,LED_Pin,GPIO_PIN_SET);
HAL_Delay(2000);
HAL_GPIO_WritePin(GPIOC,LED_Pin,GPIO_PIN_RESET);
HAL_Delay(2000);
} // END
} // END
It is also Creating same Issue if i am using USART functionality.
