I want Receive characters from USART. I don't  know how much characters will be sent
and the data that will be sent is too much. in interrupt mode i will receive amount interrupts and it is not good(for example 1000 ~2000) and in DMA mode i can not know than when the last character has been sent
and i polling mode in should check my buffer always.




what should i do ???


thank you
