Ring buffer using head and tale in STM32

Whenever UART receives data in the ring buffer, the head gets incremented by 1. And when we read that data, tale gets incremented by 1.
UART Circular buffer using DMA and IDLE line detection

UART have a feature called IDLE line detection and we are going to use this to sole the problem mentioned above. Idle line is detected on RX line when there is no received byte for more than 1 byte time length.
